Question

USE C++

Write a function named find that takes a pointer to the beginning and a pointer to
the end (1 element past the last) of an array, as well as a value. The function should
search for the given value and return a pointer to the first element with that value,
or the end pointer if no element was found.

#include<iostream>
using namespace std;

int* find(int* begin, int* end, int value){
   int* p;
   for(p=begin;p<=end;p++){
      if(*p==value){
         return p;
      }
   }  
   return p;
}

int main() 
{
    int arr[] = {3,2,4,1,7,5,6};
    int* result = find(arr,arr+7,4);
    
    cout<<*result<<endl;
    return 0;
}

int* find(int* begin, int* end, int value){
   int* p;
   for(p=begin;p<=end;p++){
      if(*p==value){
         return p;
      }
   }  
   return p;
}
