当我在OSX上的C程序中使用#include <stdio.h>
int number, total;
int main (void)
{
total = 0;
while (true) {
printf ("Enter a number (-1 to stop)\n");
scanf (" %d", &number);
if (number < 0) {
break;
}
total = number + total;
}
printf ("The total is %d", total);
return 0;
}
循环时,出现以下错误
while (true)
然而,当我在我的Windows分区(通过GCC程序)上运行它时,我没有收到错误..
这是对osx的GCC限制吗?
答案 0 :(得分:2)
将以下内容添加到文件顶部:
#include <stdbool.h>
这将定义bool
,true
和false
。
