Backslash escaping is required when embedding special characters in string literals across most programming languages. Quotes, backslashes, newlines, tabs, and null bytes all need escaping when used inside strings in C, Java, PHP, Python, JavaScript, SQL, and many other languages.
\\ — literal backslash\" — double quote inside a double-quoted string\' — single quote inside a single-quoted string\n — newline character (LF)\t — horizontal tab\r — carriage return\0 — null characterWindows uses backslashes in file paths (C:\Users\...), but backslash is the escape character in most languages. You must write C:\\Users\\ or use raw strings (Python r"C:\Users\...") or forward slashes (C:/Users/...).
'Add backslashes' literally prepends a backslash before specified characters. 'Escape for string literal' produces a fully escaped string ready to embed inside a quoted string literal, replacing control characters with their escape sequences.
