What is the problem does not print correct results

Question

#include <iostream>
using namespace std;
int main()
{
double x = 2, y = 1, z = 3, i = 0, j = 0, l = 0, fact = 1, fac = 1, fa = 1, n, p;
double eq = 0.0, sum = 0;
cout << "Enter n : ";
cin >> n;

for (p = 0; p < n; p++)
{
for (i = 1; i <= x; i++)
{
fact *= i;
}

for (j = 1; j <= y; j++)
{
fac *= j;
}

for (l = 1; l <= z; l++)
{
fa *= l;
}

eq += ((fact + fac) / fa);

x += 2;
y += 2;
z += 3;
}
cout << eq;

return 0;
}

Answer 1

tell us what you are making. your code excutes perfectly expect you didn't used the variable sum anywhere in your code after declaring it

Answer 2

Coding Kitty I want to calculate the numbers multiplied and then collect and divide as indicated in the matter But I didn't get the right answers.
