小编cod*_*aif的帖子

我想将枚举变量声明为值.我怎样才能做到这一点？

例如:

public enum CardSuit {
   SPADE(0), HEART(1), DIAMOND(2), CLUB(3);
}

我可以这样声明:

CardSuit s = CardSuit.SPADE;

我也想这样声明:

CardSuit s = 1;

这样做的方法是什么？这甚至可能吗？

#include <stdio.h>
#include <string.h>

int main()
{
    const char str[11]= "Hello World";
    if(-1 > strlen(str)){
        printf(str);
    }

    return 0;
}

This if condition should always return false. But here it's not. But if I put strlen(str) value to another variable and compare with that, then it works as expected. What I am missing here? Is it compiler dependent or something?
