What does the % symbol do?
For example, if num1 has the value of 120 and num2 has the value 2, what will num1%num2 generate? Thanks |

It is called the mod operator and gives remainder.
That is num1%num2 will divide num1 from num2 and will display the remainder. In your example it will return 0, as 120 is completely divisible by 2. |

So, if num2 was 24, it would give me 5 with a remainder of 0?

QUOTE(htdefiant @ Dec 15 2007, 10:28 AM)  So, if num2 was 24, it would give me 5 with a remainder of 0? It wouldn't, or i should say, shouldn't give you the 5. It's purpose is to return the remainder—nothing else. You see this in PHP, too, since PHP is based on C, as well as other programming languages. |

I think you are not getting it. Try this program in C
CODE main() { int num1,num2; printf("Enter num1 : "); scanf("%d",&num1); printf("Enter num2 : "); scanf("%d",&num2); printf("num1%num2 is %d", num1%num2); } |

That program crashes my DOS window for some reason. But I think I understand - if I put in 120 and 24, the output would be 0? Thanks for your patience

Yes, as 120 divided by 24 is exactly 5. If you used 50 and 7 then the output would be 1. If you used 99 and 4 then the output would be 3.
