Programming technique to compare objects inside of a loop without needing to loop twice

main.cpp

#include <iostream>

// find the max value in an array
int main() {
  int array[] = { 11, 100, 99, 95, 14, 62, 35, 74 };
  
  auto j = 0u;
  for (auto i = 0u; i < 8; ++i) {
    if (array[j] < array[i]) { // controls comparisions to find the maximum value without needing to loop the same array twice
      j = i;
    }
  }
  
  // by this point, array[j] is guaranteed to be the maximum value
  std::cout << array[j] << std::endl;
  return 0;
}

You can easily switch this to find the minimum value. It's not particularly complicated as a code piece, however you may find value in being reminded of this, as its not the most obvious solution
