在Linux GCC编译测试通过,代码如下:



~~~.c

#include <stdio.h>



void tobase(int, int);

int main()

{

tobase(33, 16);

return 0;

}



void tobase(int value, int base)

{

static char digits[] = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

char buf[(sizeof(long) << 3) + 1];

char *ptr, *end;



if (base < 2 || base > 36) {

printf("error base range \n");

}



end = ptr = buf + sizeof(buf) - 1;

*ptr = '\0';

do {

*--ptr = digits[value % base];

value /= base;

} while (ptr > buf && value);



printf("base: %d, => %s \n", base, ptr);

}
