Thread: my lost loop

Ok, this might look familiar. I posted this code awhile ago and I was told I had an infinate loop in it. After some time of trying to revise the code, I cannot fix the problem on my own. The problem should be in the randomnumber function. I hope you can help me.

Code:

/*Epsilon Omega Gamma*/
#ifndef _epsilonomegagamma_h
#define _epsilonomegagamma_h



void dealcomp(int number);
void dealme(int number);
bool showcomp(bool isgameover);
void showme();
void blackjack();
int randnumber();
int randnumber1;
void newround();
bool compturn();
bool myturn();
short comphand[11];
int comphandsize, comphandvalue, compace;
int myhand[11], myhandsize, myhandvalue, myace, cardsleft;
int i;
char hiddencard;
int start();
int number;
bool continuegame1;
bool continuegame2;
void start1();
bool isgameover;
char newgame;

	cardsleft=52;
