write a c program to find out the sum of series 1^3 + 2^3 + …. + n^3 | CTechnotips

Write a c program or code to find out the sum of series 1^3 + 2^3 + …. + n^3 that is sum of cube of n natural numbers.

#include<stdio.h>

#include<math.h>

int main(){

    int n,i;

    int sum=0;

    printf("Enter the n i.e. max values of series: ");

    scanf("%d",&n);

    sum = pow(((n * (n + 1) ) / 2),2);

    printf("Sum of the series : ");

    for(i =1;i<=n;i++){

         if (i != n)

             printf("%d^3 + ",i);

         else

             printf("%d^3 = %d ",i,sum);

    }

    return 0;

}

Sample output:

Enter the n i.e. max values of series: 3

Sum of the series: 1^3 + 2^3 + 3^3 = 36

Mathematical Formula:

Sum of the series 1³ + 2³ + 3³ + … + n³ = (n (n+1)/2)²
