	1. The sign is reversed. it should be <=
	int_exp1 <= int_exp2
	2. There should be 2 equal signs
	int_exp1 == int_exp2
	3. ! should be on the other side
	int_exp1 != int_exp2
	4. Cant compare a string literal using relational quotes
	char_exp == 'A'
	5. This is correct
	6. Has to have int_exp1 (on each side of operator)
	int_exp1 < 2 && int_exp1 > -10
