问题描述
我知道在C + +和PHP中,你可以填充一个字符串或文件与硬编码的文本。如果我记得正确,这是应该看起来:
I know in C++ and in PHP you can fill a string or a file with hard-coded text. If I remember correctly this is how it is supposed to look:
var <<< DELIMITER
Menu for program X
1.Add two numbers
2.Substract two numbers
3.Multiply two numbers
Please pick an option from (0-3);

这可用于菜单或文本,标题。但不必执行:
This can be used for menus or text that remains the same no matter what like a header. But without having to do:
foobar << "Menu for program X" << endl << "1.Add two numbers" << endl << "2.Substract two numbers"
