c语言问题检查与纠正

请问各位，这个代码有问题吗

• ```c
  #include<stdio.h>
  int main(void)
  {
  float radius = 0.0f;
  float diameter = 0.0f;
  float circumference = 0.0f;
  float area = 0.0f;
  float pi = 3.14159265;

  printf("Input the diameter of the table:");
  scanf("%f", &diameter);

  radius = diameter / 2.0f;
  circumference = 2.0f * pi * radius;
  area = pi * radius * radius;

  printf("\nThe circumference is %.2f", circumference);
  printf("\nThe area is %.2f\n", area);
  return 0;
  }

```

没有问题

没什么大问题，最后写上return 0;
