小编Cha*_*Sun的帖子

当我在Android Studio中"运行"我的项目时,在"消息"窗口中,我得到:

Gradle: 
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':play01:compileDebug'.
> Compilation failed; see the compiler error output for details.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

它说> Compilation failed; see the compiler error output for details. 那么"编译器错误输出"在哪里？和/或我如何运行--stacktrace选项？

鉴于:

[['x','a'], ['y','b'], ['z','a']]

我想要一个元素列表和第二个元素的计数频率:

[['x','a',2], ['y','b',1], ['z','a',2]]

当运行下面的代码时,strcpy_s失败,"Buffer is too small",据说是指目的地mem.长100个字节,显然不是太小.有任何想法吗？

int main(int argc, char* argv[])
{
    char* mem = (char*)malloc(100);
    memset(mem, 0, 100);
    strcpy_s(mem, strlen("hello"), "hello"); // <----- Assertion Fail
    printf("%s\n", mem);

    return 0;
}
