warning: return type of ‘main’ is not ‘int’

When we will compile a c program we may get following error message:

warning: return type of ‘main’ is not ‘int’

Solution:

Cause of this warning message is return type of main function is not int. It is necessary to  return an int value by main function. If main function returns 0 then operating system treat it as success.

For example:

int main(){

   //Write your c code.

}
