Default Function Arguments
A function can be called without specifying all its arguments. The function declaration must provide default values for those arguments that are not specified.

Once we provide a default value for a parameter, all subsequent parameters must also have default values.

For example:

// Invalid
void add(int a, int b = 3, int c, int d);

// Invalid
void add(int a, int b = 3, int c, int d = 4);

// Valid
void add(int a, int c, int b = 3, int d = 4);
