Following is my program for calculating the sum of exponential series upto n terms:
e = 1/0! + 1/1! + 1/2! + 1/3! + 1/4! + 1/5!+....1/n!
Code:
#include<stdio.h>
int main()
{
int n,i,p=1;
float sum=1.0,fact=1.0;
printf("enter the number of terms");
scanf("the number of terms are %d",&n);
for(i=1;i<=n;i++)
{
while(p<=i)
{
fact*=p;
p++;
}
sum+=(1.0/fact);
}
printf("the sum is %f",sum);
system("pause");
return 0;
}
While executing the code in dev-C++, the program stops executing and goes into an infinite loop after entering 'n'. Kindly help.
