How can I display a single and two quotes in a number using a variable not literal in C++? Let's say 6'2" feet

Question

I'm new using C++, my instructor wants me to print this sentence:

A 6'2" person is 74.4 inches tall

The thing is I don't know how to put the quotes, and he doesn't let me use 6 and 2, he wants me to use the variable that I previously declared for 6'2". I don't have idea how to put quotes in a variable. Also that same variable that I previously declared as height_feet, it's been using to compute a calculation, so I can't declare it as string(can I?).

double height_feet = 6.2;
double height inches = height_feet * 12);
cout << "A " << height_feet << " person is " << height_inches<< " inches tall " << endl;

look up backslash to escape the normal processing of a char. Put it in the char string litterals — doug, Sep 12 '19 at 03:46
Just about any descent book ([here's a list](https://stackoverflow.com/a/388282/440558) of good ones) or tutorial should have taught you how to *escape* special characters in a string. — Some programmer dude, Sep 12 '19 at 03:49
@v78 single quotes don't need to be escaped inside double quotes and vice versa — phuclv, Sep 12 '19 at 05:32

You can escape them in a string like this:

  string height = "6\'2\"";
  cout << "A " << height << " person is " << 1.88<< " meters tall " << endl;

Just put a slash before " or ' which you want to include as part of the string rather than part of the code.

@iammilind pointed out that you don't technically require escaping for the single quote if it is between double quotes, so whether or not you escape that is optional.

No escape is required for single quote `'`, when it appears between double quotes, i.e. `"hello 'x'."` is fine. It will be required when appearing between single quotes, such as `'\''`. – iammilind Sep 12 '19 at 03:57
I made that change. – Matthew Gaiser Sep 12 '19 at 04:04
