Hi guys.Im new to coding .I tried coding a c programm in eclipse that checks if a given number is a prime number.I keep getting error "Error encountered during Build". Where did i go wrong? How could i change the code to make it work ? Thank you in advance :)

Update: I just used the corrections suggested (pritf to printf and ;). It unfortunately still doesnt work.

Launch failed , binary not found
Build Project has encountered a problem.Errors occured during the build

What I have tried:

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

int main()
{
	int x ;
	int i, val1, val2, count=0 ;
	printf("Please enter a number:");
	scanf("%d", &x);

	val1= ceil(sqrt(x));
	val2=x;

	for (i=2; i<=val1; i++)
{
		if(val2% i == 0)
			count=1;
}
if((count == 0 && val2 !=1)||val2 == 2 || val2==3)
	printf("The number is a prime number");
else
	printf("The number is not a prime number");

	return 0;
}
