Question

Class syntaxErrors3( )

{
public:
void setY(int, int);
isEqual(int a, int b);
int multiply( );
void print( ) const;
syntaxErrors3(int, int = 0);
private:
int x;
int y;
}

What line(s) have errors?

Answer 1

The syntax errors include incorrect use of parentheses after the class name and a missing return type for the isEqual function. The multiply function may or may not be an error depending on if it was intended to have parameters.

Step-by-step explanation:

The given code contains a few syntax errors which need to be corrected. The specific lines with errors include:

• class syntaxErrors3( ){...}: The parentheses after the class name are incorrect. There should be no parentheses following the class name. Correct syntax: class syntaxErrors3 {...
• isEqual(int a, int b);: The return type is missing for the function isEqual. It should specify what type it returns, for example bool isEqual(int a, int b); if the function is intended to return a boolean.
• int multiply( );: This function declaration does not have any parameters which might be intended, but if it relies on the member variables x and y, then it is correctly specified. However, if it is supposed to take parameters, they must be added.

Other parts of the code like variable declarations and the constructor syntax are correct assuming the constructor is intended to provide a default value for the second parameter.
