Answer:
C# code:

 int userNum = 0;
 int i = 0;
 // set userNum to 3
 userNum = 3;
 // print the 'Ready!'
 printf("Ready!");
 // print the new line
 printf("\n");
 // use the for-loop to print userNum ... 2 1
 for (i = userNum; i >= 1; i--)
 {
   // print current value of i
   printf("%d", i);
   // print the new line
   printf("\n");
 } // end for-loop
 // print the 'Blastoff!'
 printf("Blastoff!");
 // print the new line
 printf("\n");
