}
a. The program has a compile error because the adjustment is missing in the for loop.
b. The program has a compile error because the control variable in the for loop cannot be of the
double type.
c. The program runs in an infinite loop because d > 10 would always be true.
d. The program compiles and runs fine.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd680ecdc-4479-4a22-983b-0535632535b1%2Fb563289a-4a0b-4c93-8dff-646248a0f6bc%2Fe4hv5gi_processed.png&w=3840&q=75)
