C语言数数问题！

为什么我输入不了甲乙两人所猜的次数？#include<stdio.h>#include<stdlib.h>#include<time.h>int x,y;int main(){ int guess(),a,b; printf("请甲开始猜数"); guess (1); printf("甲猜了%d次",&x); printf("请乙开始猜数"); guess (2); printf("乙猜了%d次",&y); if(a>b) printf("乙获胜"); else printf("甲获胜"); return 0;} int guess(int num) { int magic,i,n; srand(time(0)); magic=rand()%10+1; while(1) { scanf("%d",&n); i++; if(magic==n) break; if(magic<n) printf("大了"); if(magic>n) printf("小了"); } if(num=1) x=i; else if(num=2) y=i; return magic; }
