Answer:
public class Main
{
public static void main(String[] args) {
int [][] a = new int[4][5];
a[0][0] = 1;
a[0][1] = 2;
a[0][2] = 3;
a[0][3] = 4;
a[0][4] = 5;
a[1][0] = 10;
a[1][1] = 9;
a[1][2] = 8;
a[1][3] = 7;
a[1][4] = 6;
a[2][0] = 11;
a[2][1] = 12;
a[2][2] = 13;
a[2][3] = 14;
a[2][4] = 15;
a[3][0] = 20;
a[3][1] = 19;
a[3][2] = 18;
a[3][3] = 17;
a[3][4] = 16;
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 5; j++){
System.out.print(a[i][j] + " ");
}
System.out.print("\n");
}
}
}
Explanation:
- Inside the main method, initialize the 2D array with their respective values at the appropriate indexes.
- Iterate over the 2D array using a nested For loop.
- The outer loop iterates over the rows, while the inner loop iterates over the columns of the 2D array respectively.
- Finally inside the nested For loop, print the value of 2D array using the i and j index.
Output:
1 2 3 4 5
10 9 8 7 6
11 12 13 14 15
20 19 18 17 16
Primary storage refers to your RAM it is internal storage.
Secondary storage is any storage that is not the primary storage that permanently stores data. Examples are hard drive, tape disk drive, floppy disk drive and compact disk drive.
Off-line storage refers to any device that stores data that is not permanently attached to the computer. Example flash drives, The data remains on the storage device and can be connected to a different computer.
Python:
sentence = “this is the sentence.”
size = len(sentence)
C++:
string sentence = “this is the sentence.”
int size = sentence.size()
* Remember strings are just arrays of characters.
