Question

Write:

• Pseudocode.

• Java program.

Answer 1

PSEUDO CODE : 


Oro 1 BINARY = INPUT ('ENTER INTEGER CONTAINING ONLY OS AND 1S') DECIMAL = 0 INDEX = 0 WHILE BINARY>0: DECIMAL = DECIMAL + POWER (2, INDEX) * (BINARY%10) BINARY = BINARY/10 INDEX ++ 8 PRINT (DECIMAL)
JAVA CODE : 

import java.text.DecimalFormat;
import java.util.Scanner;

class Main {
    public static void main(String[] args) {
        //Prompt user for input
        Scanner obj = new Scanner(System.in);
        System.out.println("Enter number containing of 0s and 1s only");
        int binary = obj.nextInt();
        int decimal = 0,index=0;
        //Iterate through all digits
        while (binary>0){
            //Separate last number and multiply by weight
            decimal = decimal+(1<<index)*(binary%10);
            //Divide number by 10
            binary/=10;
            //Increment index
            index++;
        }
        System.out.println(decimal);
    }
}

OUTPUT :

Run: Main x "C:\Program Files\Java\jdk-13\bin\java.exe" "-javaagent:C: Enter number containing of Os and 1s only 1101 13 Process finished with exit code 0
