Write a program to accept the names of 10 cities in a single dimensional string array and their STD (Subscribers Trunk Dialling) codes in another single dimension integer array. Search for the name of a city input by the user in the list. If found, display "Search Successful" and print the name of the city along with its STD code, or else display the message "Search unsuccessful, no such city in the list".

import java.util.*;
public class SQ30{
public static void main(String args[]){
Scanner ob = new Scanner(System.in);
String city[] = new String[10];
String code[] = new String[10]; 
int i, flag = 0;

// INPUT 
System.out.println("Enter 10 records - City name, STD code"); 
for (i = 0; i < city.length; i++) 
{System.out.print("City:"); 
city[i] = ob.nextLine(); 
System.out.print("STD Code:"); 
code[i] = ob.nextLine(); 
}

System.out.println("\nEnter the City whose STD Code is to be searched"); 
String name = ob.nextLine(); 

// LOOP FOR SEARCH AND PRINT 
for(i=O;i<city.length;i++) 
{ if (name.equalslgnoreCase(city[i])==true) 
{ flag = 1; 
System.out.println("Search Succesful"); 
System.out.println("City: " + city[i] + "\tSTD Code: " + code[i]); 
}}

if (flag == 0)System.out.println("Search Unsuccessful .. City not listed"); 
}}
