For loop in C breaks randomly

I've been struggling with this loop in C for a while now. I'm trying to create a string array through a for loop (which I'm not sure I'm doing correctly. I hope I am). Every time I enter a string with a space in it, the for loop breaks and skips all iterations. For example, if I write S 1 in the command line, it would break.

This is the code:

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

int main(){
	int players;
	int jerseys;
	int count = 0;
	int i;
	scanf("%d", &jerseys);
	
	scanf("%d", &players);
	
	char size[jerseys], p[players][100];

	for(jerseys; jerseys > 0; jerseys--){
		
		scanf(" %c", &size[count]); 
		count++;
	}
	getchar();
	count = 0;
	for(players; players>0; players--){
		/*scanf(" %s", p[0] );	*/	/*you cant assign arrays in C.*/
		getchar();
		fgets(p[count], 100, stdin);
		printf("%s", p[count]);
		printf("%s", p[count][2]);  /* LINE 29 */
		printf("Hello\n");
		count ++;
	}		


	return 0;
}

Moreover, on line 29, if I change the index from 2 to 1, the loop instantly breaks, no matter what I put.

I have a python code for what I essentially want from C:

given = []
jerseys = int(input())
if jerseys == 0:
	print(0)
players = int(input())
j = []
requests = 0
for _ in range(jerseys):
	size = input()
	j.append(size)
for _ in range(players):
	 p = input().split()

I've looked at many places, and I think the problem is with the array, not the new lines, but I have no clue.

Edit:

This is something that would look like what I want to input(and what I usually try):

3
3
S
M
L
S 1
S 3
L 2

> If the input characters do not match the control characters or are of the wrong type for a formatted input scanf terminates leaving the offending character as the next character to be read.

If you write 1` in the command line, then jerseys set to 1, but players is a random int because the ` not match the %d format. So in you program, your players variable may be a big int.

So when you use scanf, you'd better to check the return value like

if ((scanf("%d", &players) != 1) {
    /* error handle */
}

I run the code and segmentation fault is raise.

the posted code does not cleanly compile!

since the compiler output several warnings, This statement only means the compiler made some (not necessarily correct) guesses as to what you meant.
