Question

In C language. 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:

Answer 1

The program uses loops to print the numbers from 0 to the user input.

It also uses loops to print the indented space before each iteration value.

The program in C where comments are used to explain each line is as follows:

#include <stdio.h>

int main(){

   //This declares userNum as integer

   int userNum;

   //This gets input for userNum from the user

   scanf("%d",&userNum);

   //This iterates through from 0 to userNum

   for (int i = 0; i <= userNum; i++ ) {

   //This iterates from 0 to current iteration value

       for (int j = 0; j < i; j++ ) {

   //This prints the indents

           printf(" ");         }

   //This prints the current iteration value

       printf("%d\n",i);     }

}//The program ends here

At the end of the program, the program outputs the indent, followed by the iteration value and a new line.
