C++ problem?

Why does this one give me an application error?





#include%26lt;conio.h%26gt;


#include%26lt;stdio.h%26gt;


#include%26lt;iostream.h%26gt;





int i,a,exp;


int rek(int n);





main()


{


clrscr();


cout%26lt;%26lt;"Give in base: "; cin%26gt;%26gt;a;


cout%26lt;%26lt;"Give in exponent: "; cin%26gt;%26gt;exp;


cout%26lt;%26lt;"Result is "%26lt;%26lt;rek(exp);


getch();


return(0);


}





int rek(int n)


{


return((exp==0)?1:rek(n-1)*a);


}

C++ problem?
%26gt; return((exp==0)?1:rek(n-1)*a);


................^^^





Did you mean (n==0)? exp isn't shrinking, only 'n' is.





You probably hit a "stack overflow" because the recursive calls never stop.





This error is likely due to the fact that you're referencing other global variables, which is bad practice and hides the dependency.
