Chapter 2, Problem 22SA

Explanation of Solution

Errors in the program have been pointed out below each line of code.

#include<ioStream>
ioStream should be iostream as C++ is case sensitive.

using std;
The statement is supposed to specify the namespace. Correct statement:
using namespace std;

const double  DECIMAL# = 5.50;
The name of the identifier (variable) should not contain # as only letters, digits, and underscores are allowed. Correct statement:
const double  DECIMAL = 5.50;

const string blanks = "   "
The statement should terminate with a semi-colon. Correct statement:
const string blanks = "   ";

int ()main
The brackets should come after the word main as main is a function in C++ and any function identifier is followed by brackets (empty or otherwise). Correct statement:
int main()

{
int height, weight;
(no error)

double 10%discount
The name of the identifier (variable) should not contain # as only letters, digits, and underscores are allowed. It should begin with an underscore or letters and not digits. Also the statement should be terminated with a semi-colon. Correct statement:
double discount;

double billingAmount$;
double bonus;
int hoursWorked = 45;
(no error)

height = 6.2;
The above statement does not have a syntax error. However, since the variable is of int type implicit conversion to int type will take place and the value of 6.2 would be truncated to 6, the intended functionality would not be accomplished. However, since there is no syntax error, we will keep the statement as it is.

weight = 156;
(no error)

cout << height << " " << weight << end;
The above statement ends with a wrong manipulator. It should be endl and not end. Correct statement:
cout << height << " " << weight << endl;

discount = (2 * height + weight) % 10.0
The statement has multiple errors. The % operator expects only integer operands and hence, it should be 10 and not 10.0. The semi-colon terminator is missing. Correct statement:
discount = (2 * height + weight) % 10;

price = 49.99;
The variable has not been declared properly as the data type is missing. Since the variable intends to hold a floating point value, it would be appropriate to declare it as a double type...
