C Exercises: Accepts a positive integer n less than 100 from the user and prints out the sum

C Basic Declarations and Expressions: Exercise-63 with Solution

Sum the series 1^4+2^4+4^4+...+m^4

Write a C program that accepts a positive integer n less than 100 from the user. It prints out the sum of 1⁴ + 2⁴ + 4⁴ + 7⁴ + 11⁴ + • • • + m⁴. In this case, m is less than or equal to n. Print an appropriate message.
Test data and expected output:
Input a positive number less than 100:
Sum of the series is 1024388

Sample Solution:

C Code:

#include <stdio.h>
int main() {
    int i, j, n, sum_int = 0;

    // Prompt user for input
    printf("Input a positive number less than 100: \n");

    // Read the input value
    scanf("%d", &n);

    // Check if the input is valid
    if (n < 1 || n >= 100) {
        printf("Wrong input\n");
        return 0;
    }

    j = 1;
    for (i = 1; j <= n; i++) {
        sum_int += j * j * j * j;
        j += i;
    }

    // Display the result
    printf("Sum of the series is %d\n", sum_int);

    return 0;
}

Sample Output:

Input a positive number less than 100: 68
Sum of the series is 37361622

Flowchart:

C programming Code Editor:

Previous:Write a C program that accepts a positive integer less than 500 and prints out the sum of the digits of this number.
Next: Write a C program that accepts integers from the user until a zero or a negative number, display the number of positive values, the minimum value, the maximum value and the average of all numbers.
