new keyword does two things.
1) allocate memory using new operator
2) invokes the constructor.

so the allocated memory using new should be freed only by
delete which frees the memory by calling the destructor.

But free will not do these things.

What are the two different types of polymorphism?

How to handle exception in c++, For example in a functions i am assigning memory to some variables and also in next instructions in am dividing one variable also. If this functions generates a error while allocating memory to those variable and also while dividing the variable if i divide by zero then catch block how it will identify that this error has cone from perticular instruction

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.
