To study and implement C++ 2D Array - Matrices.
visual studio code
A 2D array in C++ is an array of arrays, meaning it's a collection of elements arranged in a grid or table with rows and columns. This type of array is commonly referred to as a matrix.
Displaying a string: Step 1: Start.
Step 2: Declare a 2D integer array arr with 2 rows and 3 columns.
Step 3: Declare integer variables i and j for loop counters.
Step 4: Display the message "Enter 6 numbers: " to prompt the user for input.
Step 5: Use a nested for loop to input values into the 2D array arr: Outer loop: Iterate i from 0 to 1 (for each row). Inner loop: Iterate j from 0 to 2 (for each column within the current row). Step 5.1: In each iteration of the inner loop, take input from the user and store it in arr[i][j].
Step 6: Use another nested for loop to print the elements of the 2D array: Outer loop: Iterate i from 0 to 1 (for each row). Inner loop: Iterate j from 0 to 2 (for each column within the current row). Step 6.1: In each iteration of the inner loop, print the value of arr[i][j] followed by a space. Step 6.2: After the inner loop completes (i.e., after printing all elements in a row), print a newline to move to the next row.
Step 7: End.
