求分数的最简式，不知道错在哪

Question

#include<stdio.h>

int gys(int a, int b);

int main()

{

int a, b, q;

scanf("%d,%d", &a,&b);/*  输入格式“  数字，数字  例如：2，10  */

q = gys(a, b);

a = a / q;

b = b / q;

printf("%d/%d\n", a, b);

return 0;

}

int gys(int a, int b)

{

int x, y, c;

x = a, y = b;

while (y != 0)

{

c = x%y;

x = y;

y = c;

}

return x;

}

Answer 1

int gys(int a, int b){int x, y, c;x = a, y = b;if (x<y) { temp=x;x=y;y=temp; } while (y){c = x%y;x = y;y = c;}return x;}

Answer 2

应该是函数错了

Answer 3

怎么给我感觉像C语音啊？
