Question

Programming in C
Loops – (counting loops and sentinel loops)

Instructions:
1. Create a program that asks the user to enter a number from 1 to 25.

2. Print the statement “I'd rather be doing something else” the number of times entered by the user using a for loop.

3. Print the statement “Programming is easy” the same number of times using a while loop.

4. Print the statement “I like to have fun” the same number of times using a do/while loop.

5. Next, prompt the user to enter a series of numbers until the user enters a -1 to stop.

6. As long as the number is not -1, add the input number to an ongoing sum and print the sum and the number on the screen.

7. When the user enters a -1 print the message “Have a Great Day :)” and end the program. –the -1 should not be added to the sum.

Explanation / Answer

#include <stdio.h>

int main(void)
{
    int i,n;
    int sum = 0;
   printf("Enter a number from 1 to 25");
   scanf("%d",&n);   //input number
  
   for(i=1;i<=n;i++)
   printf(" I'd rather be doing something else"); //execute loop n times
  
   i=1;
   while(i<=n)
   {
        printf(" Programming is easy"); //execute loop n times
        i++;
      
   }
  
   i=1;
   do
   {
   printf(" I like to have fun"); //execute loop n times
   i++;
   }while(i<=n);
  
  
   printf(" Enter a series of numbers enter -1 to stop.");
   do
   {
        scanf("%d",&n);
        if(n != -1)
        {
        sum = sum+n;
        printf(" Num = %d Sum = %d",n,sum); //print number and sum
        }
        else
        break;
   }while(n!= -1);
  
   printf(" Have a Great Day !");
   return 0;
}

Output:

Enter a number from 1 to 25

Enter a series of numbers enter -1 to stop

4 Num = 4 Sum = 4

67 Num = 67 Sum = 71

12 Num = 12 Sum = 83

23 Num = 83 Sum = 106
