Apr 16, 2025 · C language provides various built-in functions that can be used for various operations and manipulations on strings. These string functions make it easier to perform tasks such as string copy, concatenation, comparison, length, etc. The <string.h> header file contains these string functions.

The strstr() function in C is a standard library function used to find the first occurrence of a substring within another string. It’s included in the <string.h> header file. This function returns a pointer to the beginning of the found substring in the string or NULL if the substring is not found.

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.

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:

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:

Apr 19, 2025 · In this guide, we’ll break down the top 9 must-know string functions in C, complete with practical examples to help you code smarter and avoid common pitfalls.

Jan 20, 2025 · In this article we will learn to write a C program to implement predefined string functions. A C program is provided below to demonstrate implementing predefined string functions like strlen, strcmp, etc.

Sep 2, 2017 · In this tutorial, we will discuss the pre-defined string function in the C Programming language. The c programming language has inbuilt string functions which are declared in string.h header file. This functions can be used in many string operations in C language. 1. strlen () – The String function can be used to calculate the length of String.

This C program allows the user to input a quiz topic, including spaces. It declares a character array quizTopic to store the input. The program uses the gets function to read the quiz topic, which allows spaces in the input. After the input is entered, the program uses puts to display the entered quiz topic on the screen.. fgets() in C

By using this predefined function, we can copy a string to another string. It requires 2 arguments of type(char*) & return(char*) only. When we are working with strcpy() from a given source address upto \0 entire content will be copied to the destination string. Syntax: char*strcpy(char*dest, const char*src);
