What is wrong with my code in C?

[Guest]

Apart from helping others with computer stuff I also do some programming. The program runs fine though but at the end it shows 

**stack smashing detected** 

So there must be something wrong. I don't know where. Hopefully people have time to read through all of it. Note: I am a beginner

#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include <string.h>

void greet (char* a);

void angerdice (char* b, int c);

int dicerolling1 ();


int main ()

{
srand (time(NULL));

int playerno;

printf ("Enter number of players: ");

scanf ("%d", &playerno);

int sel;

char playername[6][100];

int i;


for (i = 1; i <= playerno; i++)
{
	
	printf("\nEnter player %d name: ", i);

	scanf ("%s", playername[i]);
	
	greet (playername [i]);

}


printf("\nPlayer name inputted.\n");




printf("Roll the dice to determine who plays first.\n\n");

int dicecount [6];


for (i = 1; i <= playerno; i++)
{
	int ii;
	printf("%s, press 1 to roll the dice: ", playername [i]);
	
	scanf("%d",&ii);
	
	while (ii != 1)
	{
	angerdice (playername [i], ii);
	scanf("%d",&ii);
	}
	
	printf("%s rolled ",playername [i]);
	dicerolling1 ();
	printf ("%d\n\n", dicerolling1() );
	
	dicecount [i] = dicerolling1();
	
	
	
	}

int maxa;
maxa = dicecount [i];;
i = 1;
int count [6];
int ab = 1;
int maxpl;
while (i <= playerno)
{

	if (dicecount [i]>maxa)
	{
	maxa = dicecount [i];
	maxpl = i;
	}
	else if (dicecount [i] == maxa)
	{
	count[ab] = i;
	ab++;
	}
	else { }

	i++;
}
if (ab == 1)
printf ("Congratulations to %s! You will begin first.\n", playername [maxpl]);
else 
{
printf("The game can not decide who is going first because ");
printf ("2 or more players happen to have the same number on their dice.\n These players will now roll the dice again.");

if (ab == 2){
printf ("%s and " , playername [count[1]]);
printf ("%s" , playername [count[2]]);
}
else if (ab == 3)
{
printf ("%s, %s ", playername [count[1]], playername [count[2]]);
printf ("and %s" , playername [count[3]]);
}
else if (ab == 4)
{
printf("%s, %s, %s ", playername [count[1]], playername [count[2]], playername [count[3]]);
printf("and %s", playername [count[4]]);
}
else if (ab == 5)
{
printf("%s, %s, %s ", playername [count[1]], playername [count[2]], playername [count[3]]);
printf("%s and %s", playername [count[4]], playername [count[5]]);
}
else
{
printf ("Everyone");
}

printf (" will roll again.\n");


}

return 0;

}

void angerdice (char* b, int c)

	int a1;
	a1 = rand () %4;
	
	if (a1 == 1)

	else if (a1 == 2)
	printf ("Press 1 to roll the dice, %s, not %d! Try again: ", b,c);
	else if (a1 == 3)
	printf("Wrong number, try again %s: ",b);
	else if (a1 == 4)
	printf("Don't enter a random number like a %d, enter a real number 1 %s: ",c,b);
	else 
	printf("%s, please enter number 1, this should not take much time: ",b);
	
}






int dicerolling1 ()

{

srand (time(NULL));
int roll1;

roll1 = rand () %10;
roll1 = roll1 +2;



return roll1;
}

I implement the program to work with 6 players. So that could be an issue?

*found it, forgot brackets and the loop with ab is shit*

I just want to say that your inconsistency in your style format is bugging me.

 

That is all.

This code suppose to be the beginning of my program so I did not put effort in indenting shit, now I put it too much effort
