Help.

I need to write a program that calculates all the numbers from 1-100; that are odd and that are greater then 40 but smaller then 70;

If you need to write it, then write it.

What do you mean by "calculates"?

Use a for-loop.

I'm sorry the question is write a program that calculates (by this word i mean the total product example 40*41*42*43...) the product of all numbers from 1-100; However the conditions are : These numbers are odd, are greater then 40 and are smaller then 70).

You can write a for-loop, can you?

[Edonis]

Somehow i can but i'm not getting the result i want.

Show what you have so far.

#include <iostream>
using namespace std;
int main ()
{
int i=1;
int n=100;
double p;
if ((i>40)&&(i<70))
{

do
{
p=p*i;
i=i+2;
}
while (i<=n);
cout << "Product is: "
<<p
<<endl;
}
system ("pause");
return 0;
}

1 2 3 4 5 6 7 8 9 10 11 12

int i=1; int n=100; double p; if ((i>40)&&(i<70)) { do { p=p*i; i=i+2; } while (i<=n); cout << "Product is: " << p <<endl; }

p is not initialized. What should it be at start? i is 1, so this is never true. What if i would be something nice to begin with? Why go to 100, when less is enough?
