Question

Write a while loop that prints user_num divided by 2 until user_num is less than 1. The value of user_num changes inside of the loop. Sample output with input: 20 10.0 5.0 2.5 1.25 0.625

Answer 1

Answer:

The code to this question can be defined as follows:

Code:

#include <stdio.h> //defining header file

int main() //defining main method

{

float user_num; //defining float variable

printf("Enter a value: "); //message

scanf("%f",&user_num); //input value from user end

printf("%f, ",user_num); //print value

while (user_num>1) //loop to calculte value

{

user_num=user_num/2; //diving value

printf("%f, ",user_num); //print value.

}

   return 0;

}

Output:

Enter a value: 20

20.000000, 10.000000, 5.000000, 2.500000, 1.250000, 0.625000,  

Explanation:

Description of the code as follows:

• First, a float variable "user_num" is declared, in which we take input from the user-end.
• In the next step, a while loop is declared, that uses the above variable to calculates its value.
• Inside the loop variable "user_num" divide its value by 2 and holds its calculated value, to print its value the "printf" method is used that prints its value.
