Question

用C语言编写程序实现两个整数交换值

Answer 1

#include<stdio.h>
int main()
{
    int x,y,t;
    printf("请输入二个整数:\n");
    scanf("%d%d",&x,&y);
    printf("输入的二个数为：x=%d,y=%d\n");
    t=x;
    x=y;
    y=t;
    printf("交换后的二个数为：x=%d,y=%d\n");
    return 0;
}

Answer 2

void exchange(int *a,int *b){
    int c;
    c = *a;
    *a = *b;
    *b = c;
}

Answer 3

int a，b，k;
scanf（"%d%d"，&a，&b);
k=a；
a=b;
b=k;

Answer 4

Answer 5

#include <stdio.h>
main()
{
int x,y,t;
printf("请输入两个整数:\n");
scanf("%d%d",&x,&y);
printf("输入的两个整数为：x=%d,y=%d\n",x,y);
t=x;
x=y;
y=t;
printf("交换后的两个数为：x=%d,y=%d\n",x,y);
}
