Question

C++ Language

Implement a two-dimensional image using a nested loop.

1) Create an integer constant DIM and set it equal to 5. 2) Use a nested loop to print the output in terms of DIM.

Example output:

***** *---* *---* *---* *****

Answer 1

Hi...

The following program is written and tested on online compiler jdoodle.

IF any doubts please comment...

From the question it is not clear that the pattern should be in a single line or in matrix form. So I have provided the code for single line. if it should be in matrix form u can uncomment the line 21 as shown in the screenshot. if still any doubt please comment.

code:

#include <iostream>

using namespace std;

int main() {
    /*  integer constant DIM and set it equal to 5 */
    int DIM = 5;
    /* variables to iterate throught the loop */
    int i,j;
    /* nested loop to print the pattern */
    for(i=0; i<DIM; i++){
        for(j=0; j<DIM; j++){
            // check for the values where there is "*" to be printed
            if(i==0 || j==0 || i==4 || j==4){
                cout << '*';    // print star at the lines
            }
            else{
                cout << "_";    // please check here given is underscore "_" or "-"
            }
        }
        // cout <<"\n";  //un comment this line if your output should have new line after each line
    }
}

Thank you....! Please comment if any doubt
