How do you delete variables that are dynamically allocated?
It depends, especially if you are going to use C++.If you allocated the variable using the malloc call or any of its derivatives you must use the corresponding 'free' subroutine call to delete them.If you use the more modern C++ 'new' operator, then use the 'delete' operator to remove the memory dynamically in the program.
What is a macro in c plus plus?
A macro is preprocessor definition that is processed prior to compilation. All occurances of a macro within your C++ source code are replaced with the macro definition, much like an automated search-and-replace-all operation. If the macro's definition is a function with one or more arguments, then the function is inline expanded within your code, replacing the defined arguments with the arguments that were passed to the macro. However, macro functions are not type safe and cannot be debugged because they only exist in your source code; the compiler only sees the intermediate code emitted by the preprocessor, at which point all macro definitions will no longer exist. To address this problem, C++ also supports the concept of template functions, which not only eliminates any unwanted inline expansion (resulting in smaller code), but also ensures that all calls to the function are type safe and can be debugged in the normal way. That said, macro functions, when used appropriately, can greatly simplify your code and can achieve things that would be difficult if not impossible to achieve with C++ alone. The ability to use code fragments via a macro is one such possibility. However, when combined with preprocessor directives such as #ifdef DEBUG, macros can also be used to provide useful and powerful debugging routines that only exist in debug code, compiling to no code in release builds. This cannot be achieved with C++ alone.
Write c plus plus program for new and delete operator using class?
#include<iostream> class foo{ int m_data; }; int main() { foo* p=new foo; delete( foo), foo=NULL; return(0); }
How do you write a c program to calculate the circumference of the circle using macros with parameters?
// macro definitions: #define PI 3.14159265358979323846 #define CIRCUMFERENCE(radius) (2. * (radius) * PI) // use this as in CIRCUMFERENCE(21.34)
How do you delete rows with a specific words using macro?
If, for example, you wish to delete rows 4 through 6... Range("A4:A6").Select Selection.EntireRow.Delete The easiest way to learn how to do something from a Macro that can also be done manually is to click Record Macro (it doesn't matter what you name it), perform the task manually, click Stop Recording, click Macros and select the Macro that was just created, click Edit, and look at the commands that were generated by the program.

What is a macro-instruction?
The macro facility presented thus far capable of inserting blocks of instruction in place of macro calls. All of the calls to any given macro will be replaced by identical blocks. This macro facility lacks flexibility: there is no way for a specific macro call to modify the coding that replaces it. An important extension of this facility consists of providing for arguments, or parameters, in macro calls. Corresponding macro dummy arguments will appear in macro definitions. . . . A 1, DATA 1 A 2, DATA 2 A 3, DATA 3 . . . A 1, DATA 2 A 2, DATA 2 A 3, DATA 2 . . . DATA 1 DC F '5' DATA 1 DC F '10' In this case the sequence are very similar but not identical. The first sequence performs an operation using DATA1 as operand; the second perform using DATA2. They can be considered to perform the same operation with a variable parameter or argument. Such a parameter is called a macro instruction argument, or dummy argument. It specified on the macro name line and distinguish by the ampersand which always its first character
