How do I make this code look and work better?

#include <stdio.h>
int main() {

	int life;
	int up;
	char chr;
	int n;
	// printf() displays the string inside quotation
	printf("Welcome to snake.\n");

	printf("Hi, this is a game snake. The snake game is a simple game, basically, you have to move around, and eat food, without hitting yourself or the walls. Every time you eat, the snake grows bigger, making it harder.\n");
	printf("Before we start, How many lifes do you want?");
	printf("Enter a number:/t");
	scanf("%c",&chr);
	printf("You chose %c ", chr);
	printf("lives.\n");
	printf("You have %c", chr);
	printf("Lives\n");
	if (char == null;)
	{
		printf("That is not a number\n");
	}
	return 0;
}
