Write a C program using string functions to perform the following functionalities: Assume: The array size as 50.To concatenate two strings.To find the length of a string.To copy one string to another.To find the size of a string.To compare two strings.Write each functionality as different function and call it from the main program.Sample InputEnter String1: VelloreEnter String2: ChennaiSample OutputConcatenated string:  VelloreChennaiLength of the string1: 7String1: ChennaiSize of string2: 50String1 and String2 are not equal

Sure, here is a step-by-step guide to writing a program in C that performs the mentioned functionalities:

1. Start by including the necessary header files:

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

2. Define the maximum size of the array as 50:

#define MAX_SIZE 50

3. Declare the functions that will perform the required functionalities:

void concatenateStrings(char str1[], char str2[]);
int findStringLength(char str[]);
void copyString(char str1[], char str2[]);
int findStringSize(char str[]);
int compareStrings(char str1[], char str2[]);

4. Implement the function to concatenate two strings:

void concatenateStrings(char str1[], char str2[]) {
    strcat(str1, str2);
    printf("Concatenated string: %s\n", str1);
}

5. Implement the function to find the length of a string:

int findStringLength(char str[]) {
    int length = strlen(str);
    printf("Length of the string: %d\n", length);
    return length;
}

6. Implement the function to copy one string to another:

void copyString(char str1[], char str2[]) {
    strcpy(str1, str2);
    printf("String1: %s\n", str1);
}

7. Implement the function to find the size of a string:

int findStringSize(char str[]) {
    int size = sizeof(str);
    printf("Size of string: %d\n", size);
    return size;
}

8. Implement the function to compare two strings:

int compareStrings(char str1[], char str2[]) {
    int result = strcmp(str1, str2);
    if (result == 0) {
        printf("String1 and String2 are equal\n");
    } else {
        printf("String1 and String2 are not equal\n");
    }
    return result;
}

9. Finally, write the main program to call these functions and get user input:

int main() {
    char str1[MAX_SIZE], str2[MAX_SIZE];

    printf("Enter String1: ");
    scanf("%s", str1);

    printf("Enter String2: ");
    scanf("%s", str2);

    concatenateStrings(str1, str2);
    findStringLength(str1);
    copyString(str1, str2);
    findStringSize(str2);
    compareStrings(str1, str2);

    return 0;
}

That's it! Compile and run the program, and you should see the desired output based on the sample input provided.

}

int findStringLength(char str[]) {
    int length = strlen(str);
    printf("Length of the string: %d\n", length);
    return length;
}

6. Implement the function to copy one string to another:

void copyString(char str1[], char str2[]) {
    strcpy(str1, str2);
    printf("String1: %s\n", str1);
}

7. Implement the function to find the size of a string:

    int size = sizeof(str);
    printf("Size of string: %d\n", size);
    return size;
}

int compareStrings(char str1[], char str2[]) {
    int result = strcmp(str1, str2);
    if (result == 0) {
        printf("String1 and String2 are equal\n");
    } else {
        printf("String1 and String2 are not equal\n");
    }
    return result;
}

int main() {
    char str1[MAX_SIZE], str2[MAX_SIZE];

    printf("Enter String1: ");
    scanf("%s", str1);

    printf("Enter String2: ");
    scanf("%s", str2);

    concatenateStrings(str1, str2);
    findStringLength(str1);
    copyString(str1, str2);
    findStringSize(str2);
    compareStrings(str1, str2);

    return 0;
}

That's it! Compile and run the program, and you should get the desired output.
