highest to lowest

[sam1guy]

im new to c++ and i am having a bit of trouble in finding lowest value. the lowest value is always returning 1 or -1 sometimes. i appreciate any help, thank you.

 #include<iostream>

using namespace std;

int main(){
	
	int scores[5];
	int highest,lowest;
		
highest=scores[0];
lowest=scores[0];

	for(int x = 0; x<5; x++){
		cout<<"Enter score for student " <<x+1 <<" : ";
		cin>>scores[x];
		
			if(highest<scores[x]){
				highest=scores[x];
			}
		
			else if(lowest>scores[x]){
			lowest=scores[x];
			}
	
	}

	cout<<"Highest score is: " <<highest <<endl;
	cout<<"Lowest score is: " <<lowest <<endl;
	
}

What are the values of 'highest' and 'lowest' on line 12?

(Remember that you will compare to those values after the user has given the first score.)

#include <iostream>
#include <limits>

int main()
{
   const int maxScores = 5;
   int scores[maxScores];

   // get a number lower than the lowest possible input
   int highest = std::numeric_limits<int>::min();
   
   // get a number higher than the highest possible input
   int lowest = std::numeric_limits<int>::max();

   //highest = scores[0]; // the scores array filled with garbage values
   //lowest = scores[0];

   for (int x = 0; x < maxScores; x++)
   {
      std::cout << "Enter score for student " << x + 1 << ": ";
      std::cin >> scores[x];

      if (highest < scores[x])
      {
         highest = scores[x];
      }

      if (lowest > scores[x])
      {
         lowest = scores[x];
      }
   }

   std::cout << "Highest score is: " << highest << '\n';
   std::cout << "Lowest score is: " << lowest << '\n';
}

Enter score for student 1: 5
Enter score for student 2: 25
Enter score for student 3: 18
Enter score for student 4: 4
Enter score for student 5: 6
Highest score is: 25
Lowest score is: 4
