gcc 选项:在没有 return 语句的非空函数上发出警告
是否有人知道 gcc/g++ 选项会在函数具有非 void 返回值但在其定义中不包含 return 语句时生成错误/警告?
Does anyone know a gcc/g++ option that generates an error/warning if there's a function that has a non-void return value but doesn't contain a return statement in its definition?
例如:
int add(int a, int b)
{
a+b;
}
非常感谢！
推荐答案
-Wreturn-type.它由 -Wall 启用(您应该始终使用它，以及 -Werror -Wextra).
-Wreturn-type. It's enabled by -Wall (which you should always be running with, along with -Werror -Wextra).
