Copies a string from the source to the destination. Copies n characters from source to the destination. Concatenate one string to the end of another.

String Functions. C also has many useful string functions, which can be used to perform certain operations on strings. To use them, you must include the <string.h> header file in your program:

Apr 3, 2025 · String functions in C are built-in functions provided by the C standard library (in <string.h>) that help you perform common operations on strings, such as finding their length, copying, comparing, concatenating, or searching within them.

Mar 5, 2023 · string.h is a standard header file in the C language that contains functions for manipulating strings (arrays of characters). <string.h> header file contains some useful string functions that can be directly used in a program by invoking the #include preprocessor directive. Syntax: Example: <string.h> header file contains the following functions:

C string Functions. The <string.h> library has many functions that allow you to perform tasks on strings. A list of all string functions can be found in the table below:

Sep 24, 2017 · In this guide, we learn how to declare strings, how to work with strings in C programming and how to use the pre-defined string handling functions. We will see how to compare two strings, concatenate strings, copy one string to another & perform various string manipulation operations.

This C program lets the user enter a quiz topic with spaces. It stores the input in the topic array using fgets. The program then removes the newline character added by fgets. Finally, it shows the entered quiz topic on the screen. String Manipulation Functions in C. Here’s the list of String Manipulation Functions in C:

Jan 25, 2025 · Use C functions like strlen(), strcpy(), strcat(), and strcmp() for string operations. String literals (e.g., "Hello") are read-only and cannot be modified. Use scanf() for input without spaces and fgets() for input with spaces.

String functions in C are pre-defined functions that allow programmers to manipulate strings efficiently. They are part of the C standard library and provide various operations that simplify the process of working with character arrays.

Apr 24, 2025 · Learn all major string handling functions in C with syntax and examples. Understand how to use strlen(), strcpy(), strcat(), strcmp(), and more in simple terms.
