Question

Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints:

0

1

2

3

Answer 1

// Import required package

import java.util.Scanner;

// create a class for userNum

public class userNum

{

// main function

public static void main(String[] args)

{

// initialize the required variables.

int userNum = 0;

int i_num = 0;

int j_space = 0;

// make an object of scanner class

Scanner scan = new Scanner(System.in);

// Display message to user, asking for input

System.out.print("userNum :");

// take input from user

userNum = scan.nextInt();

// iterate the loop till the user input

for (i_num = 0; i_num <= userNum; i_num++)

{

// iterate the loop for blank spaces

for (j_space = 0; j_space < i_num; j_space++)

{

// Use space in output

System.out.print(" ");

}

// display the number in output.

System.out.println(i_num);

}

// return

return;

}

}

// include required header files

#include <iostream>

using namespace std;

// start with main function

int main()

{

// initialize required variables

int userNum;

int i_num=0;

int j_space=0;

// display message

cout<<"userNum: ";

// take input from user

cin>>userNum;

// iterate loop for numbers accepted by user.

for(i_num=0;i_num<=userNum;i_num++)

{

// iterate loop for spaces.

for(j_space=i_num;j_space>0;j_space--)

{

// display blank spaces.

cout << " ";

}

// display numbers

cout << i_num << endl;

}

return 0;

}

// include required header files

#include <stdio.h>

// start with main function

int main(void) {

// initialize required variables

int userNum;

int i_num=0;

int j_space=0;

// Display message.

printf("userNum: ");

// take user input

scanf("%d", &userNum);

// iterate loop for numbers accepted by user.

for(i_num=0;i_num<=userNum;i_num++)

{

// iterate loop for spaces.

for(j_space=i_num;j_space>0;j_space--)

{

// display blank spaces.

printf(" ");

}

// display numbers

printf("%d\n",i_num);

}

return 0;

}

Code to copy:

# Take input from user and store in userNum variable

userNum=int(input("userNum : "))

# iterate loop in the range of user input

for i_num in range(userNum+1):

# iterate loop for blank spaces

for j_space in range(i_num):

# print blank spaces

    print(" ",end="")

# print the numbers

print(i_num)
