Simple Example of Function Overloading by Matee Gojra

/* Function Overloading is a Popular C++ Technique in Which a Functions of Same name works in a Different Methods, Functions can be Different in Following Aspects:

1- Number of Parameters

2-Types of Parameters

3-Difference in Return Type  */
