Question

"Create a program that displays a table consisting of four rows and five columns. The first column should display the numbers 1 through 4. The second and sub-sequent columns should display the result of multiplying the number in the first column by the numbers 2 through 5. If necessary, create a new project named Introductory14 Project, and save it in the Cpp8\Chap08 folder. Enter the C++ instructions into a source file named Introductory14.cpp. Also enter appropriate comments and any additional instructions required by the compiler. Save and then run the program."

I need help with making this C++ code. it needs to be done using a POST-TEST loop and i am not sure how to use "do" and "while"

Answer 1

code in c++ (code to copy)

#include<bits/stdc++.h>
using namespace std;
int main()
{
        // create  a table consisting of four rows and five columns
        int table[4][5];
        // The first column should display the numbers 1 through 4
        int i=0;
        while(i<4){
                table[i++][0]=i;
        }
        // The second and sub-sequent columns should display 
        // the result of multiplying the number in the first
        // column by the numbers 2 through 5
        int col=1;
        // using a post test loop
        while(1){
                //break from loop of column value is 5
                if(col==5){
                        break;
                }
                int row=0;
                // using a post test loop
                while(1){
                        //break from loop of row value is 4
                        if(row==4){
                                break;
                        }
                        // result of multiplying the number in the first column by the numbers 2 through 5
                        table[row][col]=table[row][0]*(col+1);
                        row++;
                }
                col++;
        }
        //print the table
        for(int i=0;i<4;i++){
                for(int j=0;j<5;j++){
                        cout<<table[i][j]<<" ";
                }
                cout<<endl;
        }
}
