Question

这两个代码有啥区别？

​​​​

#include <stdio.h>
int main()
{
    int a = 0;
    int b = 0;
    scanf("%d %d ", &a, &b);
    int sum = a + b;
    printf("sum=%d\n", sum);
    return 0;
}

#include <stdio.h>
int main()
{
    int a = 0;
    int b = 0;
    int sum = 0;    
         scanf("%d %d\n", &a, &b);
    sum = a + b;
    printf("sum=%d\n", sum);

    return 0;
}

没有本质的区别，唯一是 scanf
scanf("%d%d", &a, &b);
推荐这样写
