The void keyword, used in the previous examples, indicates that the function should not return a value. If you want the function to return a value, you can use a data type (such as int, string, etc.) instead of void, and use the return keyword inside the function:...
This was previously returning a const char* pointer to a std::string.c_str() This has been a source of bugs in the past if the backing std::string goes out of scope or the caller tries to modify it.main (#3009) v0.82.0 … help weirddan455 committed Oct 15, 2023 1 parent 5b...
在一个编译器(VS)上的代码移植到另一个编译器(DEVCPP)上,就报错了。在这记录并分享一下。 使用场景: 今天在代码移植时。把c++代码,移植到DEVCPP后,进行编译。提示报错。报错内容 [Error] ‘::main’ must return ‘int’。就纳闷了好好地代码怎么就不行了。 如下图: 看......
