Accepting Word/Sentence Answers

Say I give out a question, what is the code to accept a long or even one word answer.

Example:

the program asks the question "What is the capital of the US?" How can you accept the answer.

Sorry this sounds dumb but I have only done number answers.

You'd either use a character array, or a string.
character arrays go something like this:

Code:

char    capital[20]; //The brackets mean it's an array, the 20 means 
                             //that you can have up to 20 values in your array

cin >> capital;

strings are like this:

Code:

#include <string>  //This is at the top of your program(before main)

//in main do this:
string capital;  //This makes a string variable and calls it captial.

cin >> capital; //This will get one word answers, but if there's a space it'll end there.
//or

getline(cin, capital); //This gets a whole line for the capital string.
