Problem Statement - Function overloading identification

Which function(s) out of the following can be considered as overloaded function(s) in the same program? Also, write the reason for not considering the other(s) as overloaded function(s).

void Execute(char A,int B); //Function 1
void Execute(int A,char B); //Function 2
void Execute(int P=10); //Function 3
void Execute(); //Function 4
int Execute(int A); //Function 5
void Execute(int &K); //Function 6

Solution

TC++ #5231

This question can have one of multiple answers.

Answer 1:
1, 2, 3 are overloaded and 4,5,6 are not.
4,5,6 will be ambiguous in relation to function 3.

Answer 2:
1, 2, 4,5 are overloaded and 3,6  are not.
3,6 would be ambiguous to function 5 as that also has one single int parameter.

Answer 3:
1,2,4,6 are overloaded and 3,5 are not.
3,5 would be ambiguous to as redeclaration error may come against function 6

 

Notes

  • Such question can have multiple answers for the reason that order is not determinable for such question when stray codes are provided.

Common Errors

  • Student often forget that overloading is never due to returned data type, it only depends on parameters passed to a function. It would be data type and cont of parameters.
