[Courses] [C] Lesson Three: Basic Declarations & Expressions

[Anand R]

I tried doing the parenthesis thing around 9/(3-3) and got this:

[root at tux linuxchix]# ./a
9
12
1
2
6
2
Floating point exception (core dumped)

	{
		printf("%d\n", 1 + 2 * 4);
		printf("%d\n", (1 + 2) * 4);
		printf("%d\n", 5 / 3);
		printf("%d\n", 5 % 3);
		printf("%d\n", 8 - 4 / 2);
		printf("%d\n", (8 - 4) / 2);
		printf("%d\n", 9 / 3 - 3);
		
		return 0;
	}
