### Write a c program to find out the sum of series 1^3 + 2^3 + …. + n^3

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

6. Write a c program to find out the sum of given H.P.

If you have any suggestions on above sum of cube of n natural numbers, please share us.

Hi Dj,

#include "math.h"
int main(){

int sum=0,i=0,n;
scanf("%d",&n);

for(i=1;i<=n;i++){
sum = sum + pow(i,i+1);
}

printf("Sum of series: %d" sum);

}

Mr. Ritesh I need help in the following :
1. 1+1=1
2. 1+2=3
3. 1+2+3=6
4. 1+2+3+4=10 Where N will come from keyboard input.

printf("1");
for(i=2,j=3;i<=n;i++,j=j+2)
{
x=pow(i,j);
sum=sum+x;
printf(" + %d^%d",i,j);
}
printf("=%ld",sum+1);
getch();
}

Design an algorithm to find the sum of the first n terms of the series. fs=0!+1!+2!+3!+……+n!(n>=0).
