Hello, I'm new to C programming and would appreciate if someone would help with this.

Every time I run the following the program "stops" at the line where the gCD function takes in values (I've tried it without this line and it doesn't stop).

Code:int abs(int a) { int A=a; if (a<0) A=-a; return(A); } int gCD(int a, int b) { int gcd = 1; while(a % 2 == 0 && b % 2 == 0) { gcd *= 2; a /= 2; b /= 2; } while (a % 2 == 0 || b % 2 == 0) { a /= 2; b /= 2; } int c = abs(a - b); while (c % 2 == 0) { c /= 2; } gcd *= c; return(gcd); } int main() { int N; int D; printf("Type a numerator: "); scanf("%d", &N); getchar(); printf("\nType a denominator: "); scanf("%d", &D); getchar(); int gcdCN = gCD(N,D); N /= gcdCN; D /= gcdCN; printf("Simplified numerator: %d\n", N); printf("Simplified denominator: %d\n\n", D); getchar(); return 0; }

Thanks!
