题目描述

请编写“#define SQR(x) …”，实现计算x的平方。

#include <stdio.h>
/******************************************/
/// Write your code here,
/// beginning with “#define”…

/******************************************/
int main()
{
int a[55];
int n, i;
scanf("%d", &n);
for(i = 0; i < n; i++)
{
scanf("%d", &a[i]);
printf("%d\n", SQR(a[i]));
}
if(n >= 5)
printf("%d\n", SQR(a[3] + a[4]));
return 0;
}
