Master String Manipulation in C with Standard Library Functions

You need to often manipulate strings according to the need of a problem. Most, if not all, of the time string manipulation can be done manually but, this makes programming complex and large.

To solve this, C supports a large number of string handling functions in the standard library "string.h".

Few commonly used string handling functions are discussed below:

Function Work of Function strlen() computes string's length strcpy() copies a string to another strcat() concatenates(joins) two strings strcmp() compares two strings strlwr() converts string to lowercase strupr() converts string to uppercase

String handling functions are defined under "string.h" header file.

#include <string.h>

Note: You have to include the code below to run string handling functions.

gets() and puts()

Functions gets() and puts() are two string functions to take string input from the user and display it respectively as mentioned in the previous chapter.

#include<stdio.h>
int main()
{
 char name[30];
 printf("Enter name: ");
 gets(name); //Function to read string from user.
 printf("Name: ");
 puts(name); //Function to display string.
 return 0;
}

Note: Though, gets() and puts() function handle strings, both these functions are defined in "stdio.h" header file.
