C Exercises: Print the square of each one of the even values from 1 to a specified value

C Basic Declarations and Expressions: Exercise-30 with Solution

Print squares of all even numbers up to a given value

Write a C program to find and print the square of all the even values from 1 to a specified value.

C Code:

#include <stdio.h>
int main() {
    int x, i; // Declare variables for user input and loop counter
    printf("Input an integer: ");
    scanf("%d", &x); // Prompt user for an integer

    printf("List of square of each one of the even values from 1 to a %d :\n", x);

    for(i = 2; i <= x; i++) { // Loop through numbers from 2 to x
        if((i%2) == 0) { // Check if the number is even
            printf("%d^2 = %d\n", i, i*i); // Print the square of the even number
        }
    }

    return 0;
}

Sample Output:

List of square of each one of the even values from 1 to a 4 :                                        
2^2 = 4                                                                                              
4^2 = 16

Previous: Write a C program that read 5 numbers and sum of all odd values between them.
Next: Write a C program to check a given integer is positive even, negative even, positive odd or negative odd. Print even if the number is 0.
