What does it mean when there are line breaks in a constant?

In computer programming, a newline character in constants is a way to represent the special character sequence ‘\n’. ‘\n’ represents a newline character, used in strings or texts to indicate a line break.

When using constant strings in your code, you can use `\n` to represent a line break. For example, the following code demonstrates how to use a line break in a string constant:

#include 
int main() {
    printf("Hello, world!\n");
    printf("This is a new line.\n");
    return 0;
}

In the example above, the two `printf()` statements print two lines of text. The `\n` at the end of each string constant represents a newline character, used to create a new line in the output.

Similarly, in other programming languages such as Python, Java, and JavaScript, the `\n` is commonly used to indicate a line break. Line breaks are useful for formatting output and making text more readable.
