将变量值保存为字符串
问题描述：
我正在努力做一件看似简单的事情，我无法做到。我想知道是否有人可以提供帮助。 :(
我想将变量的值传递给字符串。变量可以是任何类型，int，string等。
理想情况下，我需要类似的东西，
cout<< var1;
但是我希望将var1的值复制到std :: string变量中。我该怎么办？：（

I want to pass in the value of a variable into a string. The variable can be of any type, int, string, etc.
Ideally I want something like,
cout<<var1;
but I want the value of var1 copied into a std::string variable. how can I do this? :(
