This c++ code return index of array correct but if value not found then not returning appropriate return what is the problem

Question

#include <iostream>
using namespace std;
class Search{
public:
int arr[6]={16,34,35,58,50,26};
int key=32;
int search(){
for(int i=0;i<sizeof(arr);i++){
if(arr[i]==key){
return i;
}
}
return -1;
}

};
int main() {
Search obj;
cout<<obj.search()<<endl;
return 0;
}

Answer 1

rajendra , this is because sizeof(arr) will return the amount of memory whole array is taking(6*4(because of int data type)=24) instead of giving the length of the array(which should be 6)

A simple fix is to devide the sizeof(arr) with sizeof(arr[0]) to get the length of the array.
