Sum of Series||C language||programming_info ||Series problem 4

To find out the sum of series 

1^3 + 2^3 + …. + n^3

Solution using C language:

1. #include<stdio.h>
2. #include<math.h>
3. int main() {
4. int n,i;
5. int sum=0;
6. printf("Enter the n i.e. max values of series: ");
7. scanf("%d",&n);
8. sum = pow(((n * (n + 1) ) / 2),2);
9. printf("Sum of the series : ");
10. for (i =1;i<=n;i++) {
11. if (i != n)
12. printf("%d^3 + ",i); else
13. printf("%d^3 = %d ",i,sum);
14. }
15. return 0;
16. }

Output:

Enter the n i.e. max values of series: 3
Sum of the series: 1^3 + 2^3 + 3^3 = 36
