Chapter 2, Problem 10SA

Explanation of Solution

double conversion = 2.5;                  //Line 1

The above declaration is a correct one as the variable is correctly declared and initialized with a floating-point number.

char grade = 'B+';                   //Line 2

The above declaration is incorrect as a char type variable is just a single character, whereas here we have two characters, B and +. Hence, it should be declared as a string type. The correct declaration would be:

string grade = "B+";

double 28.5 = num                   //Line 3

The above declaration is incorrect as the declaration does not end with a semi-colon. The correct one would be:

double 28.5 = num;

string message = ''First C++ course';            //Line 4

The above declaration is incorrect as the value must be within double quotes...
