#include "stdio.h"
#define TRUE 1
#define FALSE 0
#define SQ(x) (x)*(x)
void main()
{
int num;
int again=1;
printf("\40: Program will stop if input value less than 50.\n");
while(again)
{
printf("\40:Please input number==>");
scanf("%d",&num);
printf("\40:The square for this number is %d \n",SQ(num));
if(num>=50)
again=TRUE;
else
again=FALSE;
}
}
开头的几句都是什么意思啊
#define TRUE 1
#define FALSE 0
#define SQ(x) (x)*(x)
这几句我只知道是宏可是不知道怎么用
各位高手可以给我粗劣讲讲么 谢谢了
