Question

Would someone be so kind as to help me with this problem, thank you.

//Introductory22Project.cpp - displays the contents of a

//two-dimensional array, column by column and row by row

//Created/revised by <your name> on <current date>

#include <iostream>

using namespace std;

int main()

{

     int nums[2][4] = {{17, 24, 86, 35},

                        {23, 36, 10, 12}};

     //display column by column

    

     cout << endl;

     //display row by row

     return 0;

}    //end of main function

22. Follow the instructions for starting C++ and viewing the Introductory22.cpp file, which is contained in either the Cpp8Chap12Introductory22 Project folder or the Cpp8 Chap12 folder. (Depending on your C++ development tool, you may need to open the project/solution file first.) The program should display the contents of the two-dimensional array, column by column and also row by row. Complete the program using a while statement in the outer loops and a for statement in the nested loops. Save and then run the program.

Explanation / Answer

Hi, I have added the code below. I have used both nested loop and for loop inside while loop for column by column and row by row respectively. Hope this is what you wanted

//Introductory22Project.cpp - displays the contents of a
//two-dimensional array, column by column and row by row
//Created/revised by <your name> on <current date>

#include <iostream>
using namespace std;

int main()
{
int nums[2][4] = {{17, 24, 86, 35},
{23, 36, 10, 12}};

   
//display column by column
cout <<"Column By Column" <<endl;
for(int i = 0; i<4;i++) {
    for(int j = 0;j<2;j++) {
        cout<<nums[j][i]<<" ";
    }
}
cout<<endl;

  
//cout << <<endl;
//display row by row
cout <<"Row By Row" <<endl;
int k = 0;
while(k < 2) {
    for(int l = 0;l<4;l++) {
        cout<<nums[k][l]<<" ";
    }
    k++;
}
cout<<endl;


return 0;
} //end of main function

Output: -
