Definition and initialization of String and String functions

Strings are regarded as a data type, and they can be used for a variety of operations and tasks.

Depending on the programming language you're using, there are many ways to define and initialise strings. I'll give some examples using c  languages:

#include <stdio.h>

int main() {
    // Declaration and initialization of a string using a character array
    char myString[] = "Hello, Developer Indian World!";
    
    // Print the string
    printf("%s\n", myString);
    
    return 0;
}

String Functions in C:


C provides a set of standard library functions for string manipulation. Here are some commonly used string functions:
strlen - String Length:
strcpy - String Copy:
strcmp - String Compare:


#include <stdio.h>
#include <string.h>

int main() {
    char myString[] = "Hello, World!";
    
    // Get the length of the string
    int length = strlen(myString);
    
    // Print the length
    printf("Length: %d\n", length);
    
    char source[] = "Hello, World!";
    char destination[20];  // Make sure the destination has enough space
    
    // Copy the string
    strcpy(destination, source);
    
    // Print the copied string
    printf("Copied String: %s\n", destination);
    
    char str1[] = "Hello";
    char str2[] = "World";
    
    // Compare the strings
    int result = strcmp(str1, str2);
    
    // Print the result
    if (result == 0) {
        printf("Strings are equal\n");
    } else {
        printf("Strings are not equal\n");
    }
    
    return 0;
}

In these Article, a string variable is declared and initialized with a specific sequence of characters enclosed in double quotes. The syntax may vary, but the basic concept is the same: you create a variable of string type and assign a sequence of characters to it. You can use function on it and get output.
