这只是一个警告,但还是可以运行的.
意思是你的x和y没有初始值.
#include"stdio.h"
void main()
{
\x09int x,y;
\x09x=0;
\x09y=0;
\x09if (x>y)
\x09printf("%d",x);
\x09else
\x09printf("%d",y);
}
这样就没有警告了,当然运行之后自己随便赋值也行,要这样写：
#include"stdio.h"
void main()
{
\x09int x,y;
\x09scanf("%d%d",&x,&y);
\x09if (x>y)
\x09printf("%d",x);
\x09else
\x09printf("%d",y);
}
你运行时候输入 x的数值 空格 y的数值 回车就出结果了
