Question

c++ please

1. Write and testa C++ main program that:
   1. declare an array arrof 6 integers
   2. Prompt the user for 6 integer values and store them in arr.
   3. Prompt the user for a target integer target.
   4. Search for targetin arr. If targetis found to match an element in the arr, then the program prints out a message which contains the address of the found element, otherwise, if no element found then the message “the element target not found” will be printed out. The program must use the array traverling pointer notation to traverse the array.

2. Write and test a function search ( ) that searches for an integer s in an array of n elements. If s is found to match an element in the array, the function returns the address of that element; otherwise it returns NULL. The function must use the travelling pointer notation (version-1) to traverse the array. The function has the following prototype.

int* search ( int *p , int s, int n)

Answer 1

#include <iostream>

using namespace std;
int* search ( int *p , int s, int n){
//loop to iterate
for(int i=0;i<n;i++){
//checking if element is exist
//return address
if(*(p+i)==s)
return p+i;
}
//return NULL if the value does not exist
return NULL;
}
int main()
{
//declaring array of 6 elements
int arr[6];
int i,target;
//pointer to store result
int *r;
//reading 6 numbers from user
cout<<"Enter 6 numbers : ";
for(i=0;i<6;i++)
cin>>arr[i];
//reading target element
cout<<"Enter target element: ";
cin>>target;
//calling search to find the target element
r=search(arr,target,6);
//if return value is null than element not found
if(r==NULL){
cout<<"the element target not found";
}
else{
cout<<"Adress of element : "<<r;
}
  
return 0;
}
