Merits of defining a pure virtual function: It enforces derived classes to implement the function, ensuring polymorphic behavior. It enables abstract classes to define a common interface. Demerits: It can hinder flexibility as derived classes must implement the function. It may also increase code complexity.
Declaring,defining and calling function
Write a merits and demerits of using function in program
Sure: int main (void) { puts ("Hello, world"); return 0; }
design
There are two ways to declare varibles. 1. Locally 2. Globally When you declare a variable locally in any function that means it is only accessible by that function. When you declare a variable globally so it is accessible by all the functions in the program. Declaring variables with static keyword means you are setting its value null.
Analysis: Gather and analyze requirements for the program. Design: Plan the structure and components of the program. Implementation: Write the actual code for the program based on the design. Testing: Verify that the program functions as intended and fix any bugs. Maintenance: Update and maintain the program to ensure continued functionality and relevance.
which function is support by an application program
the main() function,the#include Directive, the variable definition. function prototype, program statements, the function definition,program comments and braces are the components of program in C++
yes we can run java program without using main. we can run program by declaring the variable static..
Well, you could be asking what the PURPOSE of "int" in code. If you say: int i = 0; You're declaring a variable to use in the program. int is an Integer keyword and it will store a number for you for use in loops or for doing math operations.
That's up to you, but the execution of the program begins with function main.
The main function. Every program must have a main function and it must be declared static.
