Please help the compiler gives the error that there is a missing bracket in the following code in the functions scramble and un scramble.

#include "DarkGDK.h";
#include <stdio.h>;
#include <stdlib.h>;

#define low_prn 32;
#define high_prn 129;

char* scramble_text(char* string,char *code);
char* unscramble_text(char* string,char *code);

void DarkGDK ( void )
{ 
//Still need code here to pass two string to scramble and then two to unscramble
return;
}
char* scramble_text(char* string,char* code)
{
int idx=0,idx2=0,ch,lgth,intcode;
while (idx<int(strlen(string)))
{
	intcode=int(*(code+idx2));	
	ch=int(*(string+idx));
	*(string+idx)=char(ch+intcode);
//I get a compiler error on line below saying missing bracket b4 ;
	if (int(*(string+idx))>high_prn)
	{
		*(string+idx)=char(high_prn%intcode);
		*(string+idx)=char(int(*(string+idx))+low_prn);
	}
	idx++;idx2++;
	if (idx2>int(strlen(code))){idx2=0;}
}
lgth=idx-1;
return string;
}

char* unscramble_text(char* string,char* code)
{
int idx=0,idx2=0,ch,lgth,intcode;
while (idx<int(strlen(string)))
{
	intcode=int(*(code+idx2));
	ch=int(*(string+idx));
	*(string+idx)=char(ch-intcode);
//I get a compiler error on line below saying missing bracket b4 ;
	if (int(*(string+idx))<low_prn)
		*(string+idx)=char(high_prn%intcode);
	idx++;idx2++;
	if (idx2>int(strlen(code))){idx2=0;}
}
lgth=idx-1;
return string;
}

+ Code Snippet

#include "DarkGDK.h";

#define low_prn 32;

Theres bound to be a few errors as i havent touched c for a while now but what i dont understand is why i get the errors i do when i compile i know im not using namespace or malloc but am a little confused with the errors.

Thanks any help would be greatly appreciated

The problem from what I can see are the lines

+ Code Snippet

#define low_prn 32;
#define high_prn 129;

If you remove the ; from after both lines, it should work
