Do this Using Array of Staring, Get Username and ph no from the user in run time and store it. User then should be able to find out the user name for given ph and vice versa..
Array of string*
public class GlobalMembersStringtoint
{
public static int Main()
{
int k = 0,m,n,eleCount,i,j,count = 0,ch;
int[] newarray = new int[90];

String pattern = new String(new char[10]);
System.out.print(“enter the string \n”);
fgets(String, 100, stdin);
System.out.print(“enter the pattern \n”);
fgets(pattern, 100, stdin);
