What is difference between function overloading and overriding?



What is difference between function overloading and overriding?..

Answer / niraj verma

It is possible in C++ to use the save function name for the
no of lines for different intention. Defining multiple
function with same name is know as function overloading or
function polymorphism.

Polymorphism means one function having many forms.
The overloading function must be different in its argument
list and with different data types.

Example:
#include<iostream.h>
#include<conio.h>
int square (int);
float square (float);
void main()
{
int a = 5;
float b = 2.5;
clrscr();
cout<<"square = "<<square(a);
cout<<"\n square = "<<square(b);
getch();
}
int square(int s)
{
return (s*s);
}
float square (float j)
{
return (j*j);
}

Overloading;

This program numbers the lines found in a text file. Write a program that reads text from a file and outputs each line preceded by a line number. Print the line number right-adjusted in a field of 3 spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (i.e., wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before processing the lines of the file. This version of the program should insert a new line after the last complete word that will fit within a 72-character line.
