Question

Write a while loop that lets the user enter a number. The number should be multiplied by 10, and the result assigned to a variable named product. The loop should iterate as long as product is less than 100.

Answer 1

Answer:

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

int main() // main function declaration

{

    int number,product=0; // variable declaration

    while(product<100) // while loop

   {

       scanf("%d",&number); // input a number

       product= number*10; // multiply the number by product

       printf("%d\n",product); // print the value of product

   }

 return 0; // return statement

}

Output:

• If the user enter 10 then the loop terminates for the first time and the output is 100.
• If the user enter 5,10 then the loop executes in 2 times and the output is 50 and 100.

Explanation:

• Firstly there is an inclusion of header file which understands the meaning of printf() and scanf() function.
• Then there is the main() function definition
• Then we declare a two-variable (number and product) of integer type.
• Then we define a while loop and check the condition that product value is less than 100 or not.
• Then we take input and multiply by 10.
• Then we assign the value in the product and print the product value.
