Python || Count The Total Number Of Characters, Vowels, & UPPERCASE Letters Contained In A Sentence Using A ‘For Loop’

Here is a simple program, which demonstrates more practice using the input/output mechanisms which are available in Python.

This program will prompt the user to enter a sentence, and then display the total number of uppercase letters, vowels and characters contained within that sentence. This program is very similar to an earlier project, this time, utilizing a for loop.


QUICK NOTES:
The highlighted portions are areas of interest.

Notice line 12 contains the for loop declaration. Note that each statement within the for loop block must be uniformly indented, otherwise the code will fail to compile.

Once compiling the above code, you should receive this as your output

Enter a sentence: My Programming Notes Is Awesome.

Total number of UPPERCASE letters: 5
Total number of vowels: 11
Total number of characters: 28

C++ || Stack – Using A Stack, Determine If A Set Of Parentheses Is Well-Formed

Here is another homework assignment which was presented in a C++ Data Structures course. This assignment was used to introduce the stack ADT, and helped prepare our class for two later assignments which required using a stack. Those assignments can be found here:

(1) Stack Based Infix To Postfix Conversion (Single Digit)
(2) Stack Based Postfix Evaluation (Single Digit)

REQUIRED KNOWLEDGE FOR THIS PROGRAM

Stack Data Structure
Cin.getline
#include "ClassStackListType.h"

A simple exercise for testing a stack is determining whether a set of parenthesis is “well formed” or not. What exactly is meant by that? In the case of a pair of parenthesis, for an expression to be well formed, consider the following table.


Given an expression with characters and parenthesis, ( ), [ ], and { }, our class was asked to determine if an expression was well formed or not by using the following algorithm:

======= WELL-FORMED EXPRESSIONS =======

This program uses a custom template.h class. To obtain the code for that class, click here.


QUICK NOTES:
The highlighted lines are sections of interest to look out for.

The code is heavily commented, so no further insight is necessary. If you have any questions, feel free to leave a comment below.

Once compiled, you should get this as your output
(Note: the code was compile four separate times to display different output)

====== RUN 1 ======

Enter an expression and press ENTER.
((
The expression: (( is NOT well formed!!!

====== RUN 2 ======

Enter an expression and press ENTER.
(a{b[]}c)

The expression: (a{b[]}c) is well formed...

====== RUN 3 ======

Enter an expression and press ENTER.
[(7 * 28) - 1987]

The expression: [(7 * 28) - 1987] is well formed...

====== RUN 4 ======

Enter an expression and press ENTER.
{3 + [2 / 3] - (9 + 18) * 12)

The expression: {3 + [2 / 3] - (9 + 18) * 12) is NOT well formed!!!

C++ || Char Array – Palindrome Checker Using A Character Array, ToUpper, Strlen, Strcpy, & Strcmp

The following is a palindrome checking program, which demonstrates more use of char array’s, ToUpper, Strlen, & Strcmp.

Using a constant value, by default, this program first asks the user to enter 5 words and/or sentences that they want to compare for similarity. If the text which was entered into the program is a palindrome, the program will prompt a message to the user via cout. This program determines similarity by using the strcmp function, to compare two arrays together. This program also demonstrates how to reverse a character array, aswell as demonstrates how to convert all the text which was placed into the char array from lower to UPPERCASE.

C++ || Char Array – Convert Text Contained In A Character Array From Lower To UPPERCASE

This program demonstrates how to switch text which is contained in a char array from lower to UPPERCASE. This program also demonstrates how to convert all of the text contained in a char array to lower/UPPERCASE.

REQUIRED KNOWLEDGE FOR THIS PROGRAM

Character Arrays
Cin.getline
Islower
Isupper
Tolower
Toupper
Strlen
While Loops
For Loops
Constant Variables
Setw

Using a constant integer value, this program first asks the user to enter in 3 lines of text they wish to convert from lower to UPPERCASE. Upon obtaining the information from the user, the program then converts all the text which was placed into the character array from lower to uppercase in the following order:

(1) Switches the text from lower to UPPERCASE
(2) Converts all the text to UPPERCASE
(3) Converts all the text to lowercase

After each conversion is complete, the program displays the updated information to the screen via cout.

NOTE: On some compilers, you may have to add #include < cstdlib>, #include < cctype>, and #include < cstring> in order for the code to compile.

C++ || Find The Prime, Perfect & All Known Divisors Of A Number Using A For, While & Do/While Loop

This program was designed to better understand how to use different loops which are available in C++.

This program first asks the user to enter a non negative number. After it obtains a non negative integer from the user, the program will determine if the inputted number is a prime number or not, aswell as determine if the user inputted number is a perfect number or not. After it obtains its results, the program will display to the screen if the user inputted number is prime/perfect number or not. The program will also display a list of all the possible divisors of the user inputted number via cout.

C++ || Whats My Name? – Using a Char Array, Strcpy, Strcat, Strcmp, & Strlen

Here is another actual homework assignment which was presented in an intro to programming class.

REQUIRED KNOWLEDGE FOR THIS PROGRAM

Character Arrays
Functions
Strcpy
Strcat
Strcmp
Strlen

This program first prompts the user to enter their name. Upon receiving that information, the program saves input into a character array of size 15. The program then asks if the user has a middle name. If they do, the user will enter a middle name. If they dont, the program proceeds to ask for a last name. Upon receiving the first, [middle], and last names, the program will use strcpy and strcat to copy/append the first, [middle], and last names into a completely new char array titled “fullname.” Lastly, if the users’ first, [middle], or last names are the same, the program will display that data to the screen via cout. The program will also display to the user the number of characters their full name contains using strlen.

NOTE: On some compilers, you may have to add #include < cstring> in order for the code to compile.


QUICK NOTES:
The highlighted lines are sections of interest to look out for.

CHAR ARRAY
Unlike integer arrays, a loop is not necessary in order to input data into a char array. This is highlighted on lines 32, 76, 79, and 125.

FUNCTIONS
Notice lines 18, 19, 69 and 119. When dealing with arrays, in order to pass variables to different functions, you need to include brackets[] letting the compiler know that you are passing an array variable. If you do not declare the functions as so, you will get a compiler error.

STRCPY/STRCAT
These functions are highlighted on lines 81-85, and 127-129. Read the comments within the code on those selected lines, they are helpful.

STRCMP
This compares two strings together to determine if they are the same. This is displayed on lines 92, 96, 100, and 136 when comparing the first, [middle], and last names together for sameness.

STRLEN
This finds the length of the current string, as noted on lines 89 and 133.

Once compiled, you should get this as your output:
Note: The code was compiled five separate times to display the different outputs its able to produce

C++ || Count The Total Number Of Characters, Vowels, & UPPERCASE Letters Contained In A Sentence Using A ‘While Loop’

This program will prompt the user to enter a sentence, then upon entering an “exit code,” will display the total number of uppercase letters, vowels and characters contained within that sentence. This program is very similar to an earlier project, this time, utalizing a while loop, the setw and setfill functions.


QUICK NOTES:
The highlighted portions are areas of interest.

In order to use the setfill and setw functions, remember to #include iomanip, as noted on line 2.

Notice line 17 contains the while loop declaration. The loop will continually ask the user to input data, and will not stop doing so until the user enters an exit character, and the defined exit character in this program is a period (“.”). So, the program will not stop asking the user to enter data until they enter a period.

Once compiling the above code, you should receive this as your output

Enter a sentence: My Programming Notes Is Awesome.

Total number of upper case letters:.........5
Total number of vowels:....................11
Total number of characters:................27
