如何在 C 中退出 Do While 循环后使用在 Do While 循环中输入的值

Question

I'm a newbie in C programming. I'm curious to know if it's possible to take a value entered in do while loop and use it outside the loop. Tried to code it a few times but it's not working for me. Appreciate a lot if someone could help me out in this matter.

#include <stdio.h>
int main() {
  float salary, hours, bonus;
  float rateperhour = 2.50;
  do {
    printf("Please enter hours worked: ");
    scanf("%f", &hours);
    salary = hours * rateperhour;
    if (salary > 500 && salary < 1000) {
      printf("Range: 5000-10000\n");
    } else {
      hours = 0;
    }
    printf("Salary: %.2f\n", salary);
  } while (hours > 0);
  for (bonus = 10; bonus <= 15; ++bonus) {
    salary = hours * bonus;
  }
  printf("Salary: %d", salary);
}

" How to use a value entered in a do while loop after exiting the do while loop in C? "

If the object the value is assigned to is declared outside the loop, there is no problem of accessing the object outside of the loop.

If the object is contrary declared inside the loop only, it has only its lifetime and scope within the loop.

But that is not the problem with your code.

That is not the reason why it does not print the expected output. Beside the mistake of the wrong format specifier at the last printf call:

printf("Salary: %d", salary);

instead of

printf("Salary: %.0f", salary);

or

printf("Salary: %d", (int) salary);

because salary is of type float ,

there is nothing syntactically wrong with your code as you can see here , so you might look at the logic behind the algorithm.

What you want to do in:

for (bonus = 10; bonus <= 15; ++bonus) {
   salary =hours * bonus;
  }

I mean how your Bonus system works? you add a bonus to the salary? tell me that so I can help you
