#include <stdio.h>
main()
printf("wo jiao biao ti\n");
{
    int s, x , b;
    float f, c;
    s = 300;
    x = 0;
    b = 20;
    f = x;
    while (f <= s)
    {
         c = 5.0 / 9.0 * (f - 32);
         printf("%3.0f %6.1f\n", f, c);
         f = f + b;
         getch();
    }
}
为什么把printf("wo jiao biao ti\n");放在main()后面却编译错误。请各位大虾指教、

#include <stdio.h>
main()
{
    printf("Fahrenheit to Celsius\n");
    int s, x, b;
    float f, c;
    s = 300;
    x = 0;
    b = 20;
    f = x;
    while (f <=s) {
         c = 5.0 / 9.0 * (f - 32);
         printf("%3.0f %6.1f\n", f, c);
         f = f + b;
         getch();
       }
}
那这样为什么还是编译错误的？

有些编译器要求printf要在声明变量的后面。我用win-tc和c-free都不行。
