+Chapter 1 exercise
+
+1.1 - The name and value choices are bad. ch and EOF are unclear, and should not have all capital names.
+
+1.2 - Because it is an active function, I would change the names and add comments
+		int isSmalelr(char *s, char *t) // function to compare two char values and return true if so
+
+1.3 - ... I read it
+
+1.4 - if (! strcasecmp(c,'y'))
+			return:
+
+		newLength = (length < bufSize) ? length : bufSize;
+
+		flag? 0:1;
+		quote = (*line == null)? 1: 0;
+
+		if (val)
+		bit = 1;
+
+		else
+			bit = 0;
+
+1.5 - Inserting chars and integers
+
+1.6 - Possible outputs are: 1, 2, and 4
+
+1.7 - switch(istty){
+		case (stdin):
+			break;
+		case (stdout):
+			break;
+		case (stderr):
+			break;
+		default:
+			return 0;
+		}
+
+1.8 - Count is incremented first and total is not defined. If total = 0, this statement would never be executed
+
+1.9 - The name of the definition of choice. Definition name sould not be in all caps fir an active function.
+
+1.10 - By making definitions clearer and use variable type like float, int, double. Executing function with different variables could cause wrong output or syntax errors.
+
+1.11 - First comment does not specify what the function does, but it just comments on return type
+
+		Comment in the center does not specify what to do in the if statement
+
+		Increment line counter does not give what the function is doing
