采用第三个变量形式
#include<stdio.h>
int test1_8(){
int a,b,t;
scanf("%d%d",&a,&b);
t = a;
a = b;
b = t;
printf("a = %d b = %d",a,b);
return 0;
}
#include<stdio.h>
int test1_9(){
int a,b;
scanf("%d%d",&a,&b);
a = a+b;
b = a - b;
a = a - b;
printf("a = %d,b=%d",a,b);
return 0;
}
#include<stdio.h>
int main(){
//test1_8();
test1_9();
}
