hey,
um i was wondering if anyone could help me with a program where if the user inputs a number no more than 5 digits and the program tells you how many times the number 2 appears in that number.

can someone help??

Jump to Postget it from the keyboard as a string instead of an integer, then create a loop to check each digit in the string. You don't need modules, division, shifts, or any other math operations, unless, of course, that is a requirement of the problem.

Try this bit of code:
// Loop until the number becomes 0
while(num1 != 0)
{
// Check for a 2
if((num1 % 10) == 2) count++;
// Chop off the last digit
num1 /= 10;
