swap(int *a, int *b)
{
    int temp;
    temp = *a;
    *a = *b;
    *b = temp;
}

int main()
{
    int a, b;
    int *pointer1, *pointer2;
    scanf("%d,%d", &a, &b);
    pointer1=&a;
    pointer2=&b;
    swap(pointer1, pointer2);
    printf("\nThe result is:%d,%d\n",a,b);
    getch();
    return 0;
}

这个代码怎么输出a一直都是小数，请哪个高手指点一下，谢谢！

scanf("%d,%d", &a, &b); //输入的时候要把逗号输入进去，如：3,4

#include<stdio.h>
#include <math.h>
void swap(int *a, int *b)
{
    int temp;
    temp = *a;
    *a = *b;
    *b = temp;
}

int main()
{
    int a=3, b=4;
    int *pointer1, *pointer2;
    scanf("%d %d", &a, &b);
    pointer1=&a;
    pointer2=&b;
    swap(pointer1, pointer2);
    printf("\nThe result is:%d,%d\n",a,b);
    return 0;
}

输入格式问题  scanf("%d %d", &a, &b);

可以了，谢谢大家！

#include <stdio.h>
void swap(int *a, int *b)
{
    int temp;
    temp = *a;
    *a = *b;
    *b = temp;
}

int main()
{
    int a, b;
    int *pointer1, *pointer2;
    scanf("%d,%d", &a, &b);
    pointer1=&a;
    pointer2=&b;
    swap(pointer1, pointer2);
    printf("\nThe result is:%d,%d\n",a,b);
   
    return 0;
}
这样没问题了、、、

结贴呢 我看看呵呵
