C Programming Test

The simple C programming test has a few programming tasks for you to solve. After you attempt them, I’ll be happy to provide you with solutions and explanations.

Task 1: Factorial Calculation

Write a C program to calculate and print the factorial of a given positive integer. The program should prompt the user to enter an integer and then display its factorial.

Task 2: Palindrome Checker

Write a C program that checks if a given string is a palindrome. A palindrome is a word, phrase, or sequence of characters that reads the same forwards and backward. Your program should take a string as input and print whether it’s a palindrome or not.

Task 3: Prime Number Checker

Write a C program that checks if a given integer is a prime number. The program should prompt the user to enter an integer and then display whether it’s prime or not.

Task 4: Array Sum

Write a C program that calculates and prints the sum of all elements in an integer array. The program should first ask the user to enter the size of the array and then input the elements. Finally, it should display the sum.

Task 5: Matrix Multiplication

Write a C program to perform matrix multiplication. The program should ask the user to input two matrices and then display the result of their multiplication.

Feel free to attempt these tasks, and once you’re ready, I can provide you with the solutions and explanations.
