Sum of First & Last Digit's | While Loop | Lecture #57 #cprogramming #coding #logical #whileloop

In C programming, a while loop can be used to repeatedly add five digits input by the user and calculate their sum. Below is a basic explanation and an example of how you can implement this.

Step-by-Step Explanation:
Prompt the User for Input: You will need to ask the user to enter five digits, and in each iteration of the while loop, you will capture a new digit.

Use a While Loop: The while loop can continue until you have collected all five digits (i.e., iterate 5 times).

Sum the Digits: Inside the loop, you will add each digit to a running total (a variable that stores the sum).

Print the Final Sum: After the loop finishes, print the total sum of the five digits.
Initialization: sum is initialized to 0, and count is initialized to 0 to track how many digits have been entered.
While Loop Condition: The loop runs as long as count is less than 5, meaning it will run 5 times.
Inside the Loop:
We prompt the user to input a digit.
The scanf function is used to take the user's input.
The entered digit is added to the sum of first and last digit.
We increment the count after each iteration to ensure we stop after N inputs.
Final Output: After the loop completes, the sum of the digits is printed.
In this example, the user inputs five digits: 5, 4, 3, 2, and 1.
The program adds them together and outputs the sum, which is 6.
