C++-编译-warning: no return statement in function returning...
Background
Description
#include <iostream>
using namespace std;
bool test_bool()
{
}
int main(int argc, char *argv[])
{
(void)argc,(void)argv;
bool ret;
if( (ret = test_bool()) ){
cout << "Hello World!" << endl;
}
return 0;
}
有符号的函数,没有return。实例中bool test_bool() 没有return false或者true。根据实际情况加上就好了。
