#include<stdio.h>
#include<conio.h>
long factorial(int,long);
void main()
{
int i,m;
long sum=0,k=1;
clrscr();
printf("enter ur no. of terms :");
scanf("%d",&m);
i=1;
while(i<=m)
{
k=factorial(i,k);
sum+=k;
i++;
}
printf("the sum is : %ld",sum);
getch();
}
int factorial(int i,long k)
{
return (i*k);
}
hope this also correct...
thank u
