String

Part of the Fundamentals section of Coddy's C++ journey — lesson 7 of 74.

A char is a single character (For example: 1, 6, %, b, p, ., T, etc.)

The string type in C++ is a sequence of characters that can hold multiple chars.

To use strings in C++, you must include this at the top of your code:

#include <string>

Note: While your code might work without #include <string> (because other headers like <iostream> might include it indirectly), it's considered bad practice to rely on indirect includes. Always explicitly include the headers you use directly in your code.

You also need to handle the namespace in one of these two ways:

1. Add this line after your includes:

using namespace std;

2. Don't add the using namespace line, but prefix string with std:::

std::string s1 = "This is a string";
// This works because we explicitly used std::

Notice that the string variable uses double quotation marks. In the above example, a string variable named s1 is initialized.

Both methods require #include <string>. The only difference is whether you want to write 'std::' before 'string' or not.

Here's a complete example:

#include <string>
using namespace std;  // Method 1

int main() {
    string s1 = "Hello";  // Method 1 style
    std::string s2 = "Hello again";  // Method 2 style (still works even with 'using namespace')
    return 0;
}

Beginner

Store the string I am learning to code with Coddy! in a variable named coddy.

Be sure to store the exact string value with correct casing.

Cheat sheet

A char is a single character. A string is a sequence of characters.

To use strings in C++, include the string header:

#include <string>

Handle the namespace in one of two ways:

Method 1 - Using namespace:

#include <string>
using namespace std;

string s1 = "Hello";

Method 2 - Using std:: prefix:

#include <string>

std::string s1 = "Hello";

Strings use double quotation marks and are case sensitive.

Try it yourself

#include <iostream>
#include <string>
using namespace std;

int main() {
    // Declare and initialize variables here
    
    
    // Output the values
    std::cout << "Coddy = \"" << coddy << "\"" <<std::endl;

    return 0;
}
