Programming Exercise
Problem # 19:
Write a program to calculate and display sum of the following series using for loop:
1! + 2! + 3! + 4! + 5!
Solution:
#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
int f, c, sum=0, n;
for(n=1;n<=5;n++)
{
f=1;
for(c=1;c<=n;c++)
{
f=f*c;
}
sum=sum+f;
}
cout<<"Sum of the series is:"<<sum;
return 0;
}
#include<conio.h>
using namespace std;
int main()
{
int f, c, sum=0, n;
for(n=1;n<=5;n++)
{
f=1;
for(c=1;c<=n;c++)
{
f=f*c;
}
sum=sum+f;
}
cout<<"Sum of the series is:"<<sum;
return 0;
}
