Thread: dynamic memory allocation on demand

the code is smth like that:

input is 0..9 & a..b (not checks others)
counts the base of the 'number' (max 36 - 'z'), and writes down that 'number' is in decimal

Code:

#include <stdio.h>
#include <string.h>
#include <math.h>
int main()

{
	char s[256];
	int base=0,basemax=0,i;
	long decimalone=0;
	scanf("&#37;s",&s);

	for (i=0;i<strlen(s);i++)
		{

		if (s[i]>=97)
			base=s[i]-86;
		else
			base=s[i]-47;

		if (base>basemax)
		basemax=base;

		}
				for (i=0;i<strlen(s);i++)
{ if (s[i]>=97)
decimalone+=(s[i]-87)*pow(basemax,(strlen(s)-1-i));
else decimalone+=(s[i]-48)*pow(basemax,(strlen(s)-1-i));
}


		printf("\n\n%d",basemax);

		printf("\n\n%d",decimalone);
		return 0;
}
