how to divide larger number by smaller number and express answers using quotient and remainder rather than a fraction or decimal quotient. for example if i divide 7 by 2, answer would have been given 3 as a quotient and 1 as a remainder. Divide larger number by smaller.

example:
7 / 2 = 3 r 1
2 / 7 = 3 r 1

i have done this so far but i don't know to i can always divide larger number by smaller using if and else statement.

C++

#include <iostream>
using namespace std;

int main() {

int large,small,quo,rem;
         cout << "\nEnter 2 numbers to divide: ";
	 cin >> large >> small;
	 quo = large / small;
	 rem = large % small;
	 cout << ""<< quo;
	 cout << " r "<< rem;

     return 0;
}

What you are doing is basically correct, using the '/' and '%' operators. As an alternative you can use the div and ldiv functions of the runtime library, which return the quotient and remainder in a structure. On some systems that might be slightly faster, because the remainder is usually a by-product of the division.

If the large is smaller than small, swap them:

C++

if(bigger < smaller)
{
   int tmp = bigger;
   bigger = smaller;
   smaller = tmp;
}

Here is your corrected program:

C++

#include <iostream>

using namespace std;

int main()
{ 
	int bigger, smaller;

	cout << "Enter a number:" << endl;
	cin >> bigger;

	cout << "Enter another number:" << endl;
	cin >> smaller;

	if(bigger < smaller)
	{
		int tmp = bigger;
		bigger = smaller;
		smaller = tmp;
	}

	int q = bigger / smaller;
	int r = bigger % smaller;

	cout << "Result: " << q << endl;

        if(r > 0)
	   cout << "Remainder: " << r << endl;

	return 0;
}
</iostream>
