Function Overloading and Operator Overloading

[safiajen0055]

Hello Friends,

What is function overloading and operator overloading in C++ ??
Please anyone give the answer of this question

Operator overloading and function overloading are both very much alike... i assume you're studying polymorphism

Operator overloading is basically using the same operator to perform different operations.
a popular example is using '+" operator to perform addition of numbers and concatenation of strings..
e.g
addition = 2 + 2
string = "Hello" + "world"
FullName = FName + LName


Now function overloading...In OOPs like C++, multiple functions can be written under the same name, provided that they differ in argument types and/or numbers.
e.g
void info(char *name); // if we call info(Bob) this function is executed
void info(char *name, int age); // if we call info(Bob, 18) this function is executed


Another example would be using int type and float type...we can have different types of arguments..the compiler will decide which function is called by looking at the return type (e.g float, char, int) and the number of arguments passed

Thanks for describing this in easy way ..
I understand the concept of function overloading ............. Thanks for sharing this ....
