题目：宏#define命令练习　

1.程序分析：

2.程序源代码：

#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;

}

}
