Develop a C program that reads the city name and state name from theuser as two different strings. Merge them into a new string (format iscityname@@statename) and display it.Example:Input: Enter city name and state name: Hyderabad TelanganaOutput: Hyderabad@@Telangana

Sure, here is a step-by-step guide to develop a C program that reads the city name and state name from the user and merges them into a new string:

1. Start by including the necessary header files:

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

2. Declare a function to merge the city name and state name:

void mergeStrings(char city[], char state[], char mergedString[]);

3. Implement the mergeStrings function:

void mergeStrings(char city[], char state[], char mergedString[]) {
    // Copy the city name to the merged string
    strcpy(mergedString, city);
    
    // Append "@@" to the merged string
    strcat(mergedString, "@@");
    
    // Append the state name to the merged string
    strcat(mergedString, state);
}

4. In the main function, declare variables to store the city name, state name, and merged string:

int main() {
    char city[100];
    char state[100];
    char mergedString[200];
    
    // Read the city name and state name from the user
    printf("Enter city name: ");
    scanf("%s", city);
    
    printf("Enter state name: ");
    scanf("%s", state);
    
    // Call the mergeStrings function to merge the city and state names
    mergeStrings(city, state, mergedString);
    
    // Display the merged string
    printf("Merged string: %s\n", mergedString);
    
    return 0;
}

5. Compile and run the program. Enter the city name and state name when prompted, and the program will display the merged string.

That's it! You have successfully developed a C program that reads the city name and state name from the user, merges them into a new string, and displays it.
