How do you include double quotes within a string literal in C?

Enclosing Quotes in String Literals

In C and other programming languages, string literals are enclosed in double quotes ("). However, sometimes it becomes necessary to include double quotes within a string literal. This poses a problem as the compiler interprets the embedded double quotes as the end of the string.

To overcome this issue, we can utilize escape sequences. Escape sequences allow us to insert special characters into a string literal by preceding them with a backslash (). The backslash indicates that the following character should be treated as a special character rather than its usual representation.

In the specific case of enclosing quotes within a string literal, we can escape the double quotes using the escape sequence ". This escape sequence tells the compiler to treat the double quote character as part of the string rather than as the string terminator.

For example, consider the following code snippet:

printf("She said \"time flies like an arrow, but fruit flies like a banana\".");

Here, we have escaped the inner double quotes using the " escape sequence. As a result, the output will be:

She said "time flies like an arrow, but fruit flies like a banana".

This technique allows us to include arbitrary characters, including quotes, within string literals while preserving the integrity of the string.
