All parameters with default arguments must appear to the right of those that do not. That is, once you begin giving parameters default, all subsequent parameters must also have defaults. In the question, q is not given a default

a)Show how to overload the constructor for the following class so that unitialized objects can also be created. (When creating uninitialized objects, give x and y the value 0.)
class myclass {
int x, y;
public:
myclass(int i, int j) { x=i; y=j;}
// ...
};
b)Using the class from question(a) above, show how you can avoid overload myclass() by using default arguments.

(Solved)
Most C++ compilers supply nonstandard functions that allow cursor positioning and the like. If a compiler supplies such functions, create a function called myclreol() using C++ language a function that clears the line from the current cursor position to the end of the line. However, give this function a parameter that specifies the number of character position to clear. If the parameter is not specified, automatically clear the entire line. Otherwise, clear only the number of character positions specified by the parameter.

(Solved)
In the C++ standard library is the function strtol(), which has this prototype:
long strtol|(const char*start, const **end, int base);
The function cnverts the numeric string pointed to by start into a long integer. The number base of the numeric string is specified by base. Upon return, end points to the character in the string immediately following the end of the number. The long integer equivalent of the numeric string is returned. base must be in the range 2 to 38. However, most commonly, base 10 is used.
Create a function called mystrtol() that works the same as strtol() except that base is given the default argument of 10. Demonstrate that your version works correctly.
