Rating C: 0
Rating D: 0
Assigned grade: A
Problem: Write a program that takes two positive integers A and B as input, passes them to a function that computes the LCM, and finally prints the result in the main function.

Student submission:
#include <simplecpp>
int lcm (int m, int n){
	cin >> m >> n;
	int i;
	for(i=1; i>0; i++){
		while( i%m == 0 && i%n == 0){
			cout << i << endl;
			break;
		}
	}
	return i;
}

main_program{
	int A, B;
	cin >> A >> B;
	lcm(A, B);
	cout << lcm(A, B) << endl;
}
