Program to check whether a given number is a pythons number

A number is said to be pythons number if  digits in the number are powers of the first digit,
for example, a number 24816 is a pythons number because
4=2^2
8=2^3
16=2^4
Other examples are 392781,41664,etc
//source code:

 #‎inc‬ lude. <stdio.h>  
 ‪#‎in‬ clude<math.h>  
 void main(){  
 int c1=0, c2=0, c3=0,p=2;  
 int z,d,x,y,f;  
 unsigned long int n,temp,q;  
 printf("\n Enter a number:");  
 scanf("%d",&n);  
 temp=n;
