Find the maximum and minimum between n number of array

Question

#include <iostream>
using namespace std;

int main() {
int n;
cin>>n;
int arr[n];
for(int i=0;i<n;i++){
cin>>arr[i];
}
int maxNo=0;
int minNo =0;
for(int i=0;i<n;i++){
maxNo=max(maxNo,arr[i]);
minNo=min(minNo,arr[i]);

}
cout<<maxNo<<" "<<minNo;

return 0;
}

Answer 1

#include <iostream>
using namespace std;

int main() {
int n;
cin>>n;
int arr[n];
cin>>arr[0]
int maxNo=arr[0];
int minNo =arr[0];
for(int i=1;i<n;i++){
cin>>arr[i];
maxNo=max(maxNo,arr[i]);
minNo=min(minNo,arr[i]);
}
cout<<maxNo<<" "<<minNo;
return 0;
}

Answer 2

Let's assume <n> is 5
1. Read value for 1st element (arr[0])

2. Assign that value for <minNo> and <maxNo>

3. Begin the loop while 1 < 5 rather than while 0 < 5

* No change is needed in loop body

Answer 3

yeah it's working thanks 😁
