What is function overloading?

Answer 1

Functions having same name and different signature implement the concept of function overloading.
void func1(int a) ;
void func1(char a) ;
Function signature means number of arguments and type of arguments.
void area(int a) ;//for square
void area(int a, int b) ;//for rectangle
void area(float r) ;//for circle
int a, b;float r;
area(a) calls first area function
area(a, b) calls second function
area(r) calls third area function

Answer 2

a function has a same name with different argument or function definitions
int add(int,int){
}
int add(int,int,int){
}

Answer 3

a function has a same name with different argument or function definitions
int add(int,int){
}
int add(int,int,int){
}

Answer 4
