Study Notes

Escape Sequences in C Programming

\n is the newline escape sequence, which moves the cursor to the next line when printed.
Escape sequences allow for the correct display of special characters, such as single (\') and double quotes (\"), preventing termination of string literals.
\t is the tab escape sequence, creating a horizontal space equivalent to a tab in the output.
The escape sequence \b causes the cursor to move one space to the left, effectively deleting the last character displayed.
Using escape sequences for quotes maintains clarity when writing strings that contain quotes, avoiding syntax errors in C code.
The escape sequence \f instructs a printer to advance to the next page, often used in formatted print outputs.
Correctly using escape sequences for quotes is crucial to ensure string literals are interpreted properly within the code.
In printf, to include double quotes within a string, a backslash (\) must precede the double quotes to escape them.
