小编Ram*_*ant的帖子

为什么这段代码不起作用？

#include <stdio.h>
main()
{
    UINT64_t ram = 90;
    printf("%d""\n", ram);
}

我收到以下错误:

In function \u2018main\u2019
error: \u2018UINT64_t\u2019 undeclared (first use in this function)
error: (Each undeclared identifier is reported only once
error: for each function it appears in.)
error: expected \u2018;\u2019 before \u2018ram\u2019

int main() 
{
    char boolean[][6]={"TRUE","FALSE"};
    printf("%s",boolean[(unsigned int)-1 == ~0]);
}

执行后,我认为它为FALSE.是什么原因？

vi和vim编辑器有什么区别？我希望技术观点不同,不是戏剧性的.如果您举例,那么它对我或所有读者都很有帮助.
