Question

Write a function SearchName() that takes the following three arguments: 1) A string pointer, 2) Length of the string array (int), 3) Name to search (string). The function then searches for the particular name in the string array and returns the index at which the name is found in the string array. Use a program to test the function.

Answer 1

#include<iostream>
using namespace std;
//method to search a name in the given string array
int SearchName(string *a,int length,string name)
{
   //search name in array
   for(int i=0;i<length;i++)
   {
       if(a[i]==name)//if found
       return i;//then returning index  
   }
   //if not found
   //then returning -1
   return -1;
  
}
int main()
{
   //program to test function
   string a[]={"hello","abc","xyz","oyo"};
   cout<<SearchName(a,4,"oyo")<<endl;
   cout<<SearchName(a,4,"hai")<<endl;
   return 0;
}

OUTPUT:

3
-1
