Keyboard
Explaination: it is period
Characteristics
based on vaccum tubes
they were large,slow,low capacity
Magnetic drums for primary memory
used mll
input punched cards and output printsout
expensive
get heated faster
eg. ENIAC,UNIVAC
Answer:
The display output specifies the variable's data type and returns output line by line. The print output, on the other hand, does not indicate the variable's data type and does not deliver output line by line. The print output can be used to portray any type of data, such as a string or an approximate value. The display output is a Python programming capability that is used to comprehend a line of text given by the user.
Answer:
- import java.util.Random;
- import java.util.Arrays;
- public class Main {
-
- public static void main(String[] args) {
- int n = 10;
- int [] myArray = new int[n];
- buildArray(myArray, n);
- System.out.println(Arrays.toString(myArray));
- }
-
- public static void buildArray(int[] arr, int n){
- for(int i=0; i < arr.length; i++){
- Random rand = new Random();
- arr[i] = rand.nextInt(90) +10;
- }
- }
- }
Explanation:
Firstly, create a method buildArray that take two inputs, an array and an array size (Line 12). In the method, use random nextInt method to repeatedly generate a two digit random number within a for loop that will loop over array size number of times (Line 13-15). The expression rand.nextInt(90) + 10 will generate digits between 10 - 99.
In the main program, call the build array method by using an array and array size as input arguments (Line 8). At last, print the array after calling the buildArray method (Line 9).
