Question

C++ program

Write a code segment to find the max element in each row and then store the values to the "result" array.

For example,

{ {2, 7, 9, 6, 4}, => 9
{6, 1, 8, 10, 4}, => 10
{4, 3, 7, 2, 9}, => 9
{9, 9, 0, 3, 1}, => 9
{8, 8, 7, 8, 9}, => 9
{1, 2, 1, 2, 3} } => 3

the result array has the values [9, 10, 9, 9, 9, 3]

#include <iostream>
#include <iomanip>
using namespace std;

const int SIZE=10;
int main()
{
const int NUM_ROWS = 6; // Number of rows
const int NUM_COLS = 5; // Number of columns
int result[SIZE] = {0};
int numbers[NUM_ROWS][NUM_COLS] = {

{2, 7, 9, 6, 4},
{6, 1, 8, 10, 4},
{4, 3, 7, 2, 9},
{9, 9, 0, 3, 1},
{8, 8, 7, 8, 9},
{1, 2, 1, 2, 3}};

#include <iostream>

using namespace std;

const int SIZE = 10;

int main() {
    const int NUM_ROWS = 6; // Number of rows
    const int NUM_COLS = 5; // Number of columns
    int result[SIZE] = {0};
    int numbers[NUM_ROWS][NUM_COLS] = {

            {2, 7, 9, 6,  4},
            {6, 1, 8, 10, 4},
            {4, 3, 7, 2,  9},
            {9, 9, 0, 3,  1},
            {8, 8, 7, 8,  9},
            {1, 2, 1, 2,  3}};
    for (int i = 0; i < NUM_ROWS; ++i) {
        int max = numbers[i][0];
        for (int j = 0; j < NUM_COLS; ++j) {
            if (numbers[i][j] > max)
                max = numbers[i][j];
        }
        result[i] = max;
    }
    for (int i = 0; i < NUM_ROWS; ++i) {
        cout << result[i] << " ";
    }
    cout << endl;
    return 0;
