Description

Create a function to find the base of a number

Demo Code

#include <stdio.h>  
void to_base_n(int x, int base);  
int main(void) {  
  int number;  //from   w w  w  . jav a  2 s .  co m
  int b;  
  int count;  
    
  printf("Enter an integer (q to quit):\n");  
  while (scanf("%d", &number) == 1)  
  {  
     printf("Enter number base (2-10): ");  
     while ((count = scanf("%d", &b))== 1 &&  (b < 2 || b > 10)) {  
         printf("base should be in the range 2-10: ");  
     }  
     if (count != 1)  
         break;  
     printf("Base %d equivalent: ", b);  
     to_base_n(number, b);  
     putchar('\n');  
     printf("Enter an integer (q to quit):\n");  
  }  
  printf("Done.\n");  
  return 0;  
}  
  
void to_base_n(int x, int base)   /* recursive function */  
{  
  int r;  
  
  r = x % base;  
  if (x >= base)  
     to_base_n(x / base, base);  
  putchar('0' + r);  
  return;  
}
