Question

c++

2. Write a CH function called range that returns the difference between the largest and smallest elements in an array.

Answer 1

#include <iostream>
using namespace std;

/**
* Returns the difference between the largest and smallest element of the array
* This function takes array and length of array in input
*/
int range(int *array, int length) {
   int i;
   int smallest = INT_MAX;
   int largest = INT_MIN;
   for(i = 0; i < length; i++) {
       if(array[i] < smallest) {
           smallest = array[i];
       }
       if(array[i] > largest) {
           largest = array[i];
       }
   }
   return largest - smallest;
}

int main() {
   int array[8] = {-9, 10, 20, -30, 70, 18, -25, 40};
   cout << range(array, 8) << endl;
   return 0;
}
