Thread: For Loop in C++

dear,

i am a novice of c++. the below program compiles perfectly and works as expected. However, I need to understand why the 'for loop' did not print the factorial line as many times as the loop.

Code:

// program to computer factorial

#include <iostream>

void main()
{
    unsigned int numb;       // input variable
    unsigned long fact=1;  // the factorial variable
    
    cout << "\nenter the number: ";
    cin >> numb;
    
    for(int j=numb; j>0; j--)        // initialising the loop
     fact *= j;
    cout << "Factorial is " << fact; // result is factorial
    
}

I am referring to Turbo C++ by Robert Lafore . In the previous example the same for loop was used to print several lines. I could not differentiate why the cout << did not print many lines.

can you please guide, thanks

dear fib,

many thanks for your quick reply. i am using bloodshed ide in winxp os. i tried the curly braces already it does not work. can you please have a relook. thanks.

Code:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    unsigned int numb;       // input variable
    unsigned long fact=1;  // the factorial variable
    
    cout << "\nenter the number: ";
    cin >> numb;
    
    for(int j=numb; j>0; j--)        // initialising the loop
        fact *= j;
            {
            cout << "Factorial is " << fact; // result is factorial
            }                
    system("PAUSE");
    return EXIT_SUCCESS;
}

i have deleted the windows support stuff in my original post. now i have included them too to be doubly sure that the dos-in-windows support is not the cause.

best regards

dear fib,

it works. tks.

best regards
