Answer:
The solution code is written in Java.
- import java.util.Scanner;
- public class Main {
-
- public static void main(String[] args) {
-
- String letters[] = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J"};
- Scanner scnr = new Scanner(System.in);
- int numRows;
- int numColumns;
- int currentRow;
- int currentColumn;
- numRows = scnr.nextInt();
- numColumns = scnr.nextInt();
-
- for(currentRow = 0; currentRow < numRows;currentRow++){
- for(currentColumn =0; currentColumn < numColumns; currentColumn++)
- {
- System.out.print((currentRow + 1) + letters[currentColumn] + " ");
- }
- }
- }
- }
Explanation:
Firstly, we need to create an array to hold a list of letters (Line 6). In this solution, only letters A - J are given for simplicity.
Next, we declare all the variables that we need, numRows, numColumns, currentRow and currentColumn (Line 8 - 11).
Next, we use Scanner object, scnr to prompt user to input integer for <em>numRows </em>and <em>numColumns </em>(Line 12-13).
At last, we use two-layer for loops to traverse through the number of rows and columns and print out the currentRow and currentColumn (Line 15-19). Please note the currentRow is added by 1 as the currentRow started with 0. To print the letter, we use currentColumn as an index to take out the letter from the array.
