Special character variables in C++

Posted on 2011-03-04
Last Modified: 2012-06-21
I have been trying to figure out how to correctly handle character variables " and ' in c++.
I know where the problem is in my code, it is in the line
cout<<"Enter your height in feet and inches (F' II" ") :  ";
The program now (after trial and errors) compiles and runs but I would like the user to be represented with the line
Enter your height in feet and inches (F' II"):
My current code displays the line as
Enter your height in feet and inches (F' II):
I have been spending a lot of time with this simple program, and am not able to get it correct. Can anyone help me?
Thank you.
#include <iostream>

using namespace std;

int main()
int inches, feet;

char feetCh;
char InchesCh;

cout<<"Enter your height in feet and inches (F' II" ") :  ";
cin>>feet>>feetCh>>inches>>InchesCh  ;

cout<< "Your height is " <<feet<< " ft " << inches << " inches " <<endl;

return 0;

Put a backslash before the double quote. For example:

cout<<"Enter your height in feet and inches (F' II\" ") :  ";

Make sure you use backslash, not forward slash.

You need to escape the quote characters with a backslash, i.e.
cout<<"Enter your height in feet and inches (F\' II\" ") :  ";

See also ("C++ Character Constants") and there the table "C++ Reserved or Nongraphic Characters" in particular.

You can use std::string to get the ft and inch and then can easily disply it. also if you want to get ft and inch individually, it's become easy using std::string.
Don't forget to use \'' where needed.

An escape sequence begins with a \ (backslash) followed by an alphanumeric character

\a /*alert (bell)*/
\b /*backspace*/
\f /*formfeed*/
\n /*newline*/
\r /*carriage return*/
\t /*horizontal tab*/
\v /*vertical tab*/
\\ /*backslash*/
\? /*question mark*/
\' /*single quote*/
\" /*double quote*/
\000 /*octal number*/
\xhh /*hexadecimal number*/

cout << "\nThis is\t a string\n\t\t with \"many\" escape sequences!\n";

DeepuAbrahamK, would you mind reading previous post to find out what otheres have already contributed before you do so? Thank you doing that in the future. Also, it does not really help if someone jumps on the bandwagon when seeing a word like 'escaping' and then contributes a bunch of stuff that was neither requested in the original question nor needed clarification.

I am not certain why you gave me such a small number of points. My solution was first and it was correct. jkr's answer is wrong. It's not necessary to escape single quotes in a string surrounded with double quotes. It doesn't hurt to do so, but it's wrong to say that you "need to."

Hi JimBeveridge,
I am truly sorry for giving you only 100 points, I just now tested your code, and it works also. Like you said, it is not necesssary to escape single quotes. I don't know how I can change the number of points. Any advice?

I don't believe that you can change the points on this question. The simplest solution is to click on "Ask a related question", title the new question something like "For Jim", then I'll answer it and you can accept it.

Here is the rule for escaping characters. For string constants, such as "Hello", you need to escape any double quotes, as I showed earlier. For single-character constants, such 'A', then you need to escape single quotes. For example, '\''.

The other escape characters, such as \n and \r, work a little differently. When you do \n, you don't get the letter n, you get a newline character.
