Question

C++

Find 2D array max and min.

Find the maximum value and minimum value in milesTracker. Assign the maximum value to maxMiles, and the minimum value to minMiles.

Ex: If the input is:

-10 20 30 40

the output is:Min miles: -10 Max miles: 40

#include <iostream>
using namespace std;

int main() {
const int NUM_ROWS = 2;
const int NUM_COLS = 2;
int milesTracker[NUM_ROWS][NUM_COLS];
int i;
int j;
int maxMiles = 0; // Assign with first element in milesTracker before loop
int minMiles = 0; // Assign with first element in milesTracker before loop
int value;

for (i = 0; i < NUM_ROWS; i++){
for (j = 0; j < NUM_COLS; j++){
cin >> value;
milesTracker[i][j] = value;
}
}

for(i = 0; i <= NUM_ROWS; i++) {
for(j = 1; j <= i; j++) {

cout << "";
}
}

cout << "Min miles: " << minMiles << endl;
cout << "Max miles: " << maxMiles << endl;

return 0;
}

Expert Solution

Explanation

1) Below is your updated program to find the maximum value and minimum value in milesTracker a 2D Array

2) Program in updated for following

Assign maxMiles and minMiles with first element in milesTracker before comparision loop
- maxMiles = milesTracker[0][0];
- minMiles = milesTracker[0][0];
Run comparison loop which compare each value for milesTracker 2D array with minMiles and maxMile
- if(minMiles > milesTracker[i][j]){
  minMiles = milesTracker[i][j];
  }
- if(maxMiles < milesTracker[i][j]){
  maxMiles = milesTracker[i][j];
  }

3) Save the updated program in cpp file, build and run
