help for turbo c++ program-amicable numbers

[shubhamgupta]

somebody plz help me with a program for inputing two numbers and then checking if they are amicable or not. i've just started learnign c++ and we are being made to use turbo c++ 3.0 we have been taught only very basic commands such as cout,cin,if-else,for,clrscr,getch,gotoxy and some mathematic commands such as pow and sqrt. plz guide me. i can't figure out how to start. i am not asking for a written code. i just need some guidance. help would be greatly appreciated.

Quite intresting. you can find more about amicable numbers here

One of the apporach would be to write a function to find the sum of all all proper divisor. In c you can find whether a number is proper divisor or not by using % operator.

x%y is equal to zero if y is proper divisor of x.

i know what is an amicable number!! i also know about the %(modulus) operator and its function but i can't figure out how exactly to use it.

Here's a start:

int sumdiv= 0;
for (int divisor= 1; divisor < x; divisor++)
   ...

It's your turn now ...

kind regards,
