Question

Create a basic program (C Programming) that accomplishes the following requirements:

Prints "for loop" and then uses a for statement to count from 1 to 100.

Prints "while loop" and then uses a while statement to count from 1 to 100.

Prints "do while loop" and then use a do while statement to count from 1 to 100.

Using a nested if/else statement or a switch in one of the loops , print to the screen if a number is:

Less than or equal to 10 (print less than 11 to the screen)

Greater than or equal to 11 but less than 20. (print between 10 and 20 to the screen)

Greater than 21 (print greater than 21 to the screen)

Answer 1

#include<stdio.h>

int main()
{
   int i;
  
   /* Prints "for loop" and then uses a for statement to count from 1 to 100. */
   printf("for loop\n");
   for(i=1;i<=100;i++)
   {
       printf("%d",i);
       /*

       Greater than 21 (print greater than 21 to the screen)
       */
       if(i<=10)
       {
           printf("\tless than 11");
       }
       else if(i>=11 && i<20)
       {
           printf("\tbetween 10 and 20");
       }
       else if(i>21)
       {
           printf("\tGreater then 21");
       }
       printf("\n");
   }
  
   /* Prints "while loop" and then uses a while statement to count from 1 to 100. */
   printf("\nwhile loop\n");
   i=1;
   while(i<=100)
   {
       printf("%d\n",i++);
   }
  
   /* Prints "do while loop" and then use a do while statement to count from 1 to 100. */
   printf("\ndo while loop\n");
   i=1;
   do
   {
       printf("%d\n",i++);
   }while(i<=100);
}
