#include<stdio.h>
int n_fact(int n);
void main()
{
int n,res=0;
printf("ENTER A NUMBER:-");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
res+=n_fact(n);
}
printf("%d",res);
}
int n_fact(n)
{
int result;
if(n=0)
result=1;
else
result=n*n_fact(n-1);
return(result);
}

#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
