+
+a.There should only be one “int” and it should be at the beginning(i.e. int a, b;)
+b.a can’t be signified as another variable(b) because b is not signified first
+(i.e.b = 0;      a = b;)
+c.b should be declared on a different line(i.e. int a = 0;       int b = 3.5;)
+d.Instead of quotations, it should be an apostrophe(ex. char grade = ‘A’;)
+e.Instead of char it should be int because char uses a string of letters(ex. int c = 1;)
+f.
+g.Should not be a string, should be a character, also use apostrophe
+(ex. char x = ‘T’;)
+
+6.1 #1 - 4
+
+1.	Invalid.Should be ‘y = 5 * x + 1; ’
+2.	Invalid.Should be ‘x * x + 2 * x + 1 = 0; ’
+3.	Valid
+4.	Invalid.There cannot be a 0 starting the expression
