请高手给分析分析

#include<stdio.h>
void xk3(int *a,int *b);
void xk4(int  a,int  b);
int main()
{
    int x=5,y=10;
    printf("x=%d,y=%d\n",x,y);
    xk3(&x,&y);
    printf("x=%d,y=%d\n",x,y);
    xk4(x,y);
    printf("x=%d,y=%d\n",x,y);
    return 0;
}
void xk3(int* a,int* b)
{
    int c=*a;
    *a=*b;
    *b=c;
}
void xk4(int a,int b)
{
    int c=a;
    a=b;
    b=c;
}

    printf("x=%d,y=%d\n"x,y);
    printf("x=%d,y=%d\n"x,y):

这两句少逗号
最后一句冒号换成分号

    printf("x=%d,y=%d\n",x,y);
    printf("x=%d,y=%d\n",x,y);

支持楼上的  呵呵
