Question

Find the maximum value and minimum value in milesTracker. Assign the maximum value to maxMiles, and the minimum value to minMiles. Sample output for the given program:

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 = -99; // Assign with first element in milesTracker before loop
int minMiles = -99; // 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;
}
}

/* Your solution goes here */

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

return 0;
}

Answer 1

#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 = -99;
    int minMiles = -99;

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

    minMiles = milesTracker[0][0];
    maxMiles = milesTracker[0][0];
    for (i = 0; i < NUM_ROWS; ++i) {
        for (j = 0; j < NUM_COLS; ++j) {
            if (milesTracker[i][j] > maxMiles)
                maxMiles = milesTracker[i][j];
            if (milesTracker[i][j] < minMiles)
                minMiles = milesTracker[i][j];
        }
    }

    cout << "Min miles: " << minMiles << endl;
    cout << "Max miles: " << maxMiles << endl;
    return 0;
}
