What Is Void Main

Are you curious to know what is void main? You have come to the right place as I am going to tell you everything about void main in a very simple explanation. Without further discussion let’s begin to know what is void main?

What Is Void Main?

In the world of programming and computer science, numerous terms and concepts are used to describe different aspects of coding and software development. One such term is “void main.” Often encountered in programming languages like C and C++, void main holds a significant role in defining the entry point and execution of a program. In this blog, we will explore the meaning and purpose of void main, its usage, and its importance in the programming world.

Understanding Void Main:

Void main is a programming construct used to define the starting point or entry point of a program in certain programming languages. It serves as the initial function that is executed when a program is run. The term “void” in void main indicates that the function does not return any value.

Usage And Syntax:

In languages like C and C++, the syntax for defining void main typically follows a specific format. Here is an example:

#include <stdio.h>

void main() {

    // Program statements and logic go here

    // …

    printf(“Hello, World!”);

    // …


In this example, the “void” keyword denotes that the main function does not return any value. The main function is the entry point where program execution begins. The program statements and logic are written within the curly braces {} following the main function declaration.

Importance And Execution Flow:

The void main function serves a crucial role in a program’s execution flow. When a program is run, the operating system calls the main function to start executing the program’s instructions. The statements within the main function are executed sequentially, allowing the program to perform specific tasks, such as data processing, calculations, or user interactions.

Within the main function, various programming constructs and control flow statements, such as loops, conditionals, and function calls, can be used to structure and control the program’s behavior. Additionally, other functions and modules can be invoked from within the main function to perform specific tasks, enhancing code modularity and organization.

It’s worth noting that the void main construct is specific to certain programming languages, particularly C and C++. Other languages, like Java and C#, have different conventions for defining the program entry point.


Void main serves as the starting point and entry function in certain programming languages, playing a crucial role in executing program instructions. Understanding the purpose and usage of void main allows programmers to structure and organize their code effectively, defining the flow of execution and enabling the creation of complex and functional software applications. As you delve further into the world of programming, grasping the concept of void main and its role in different programming languages will aid in your journey of mastering the art of coding.


What Is The Meaning Of Void Main?

The void main() indicates that the main() function will not return any value, but the int main() indicates that the main() can return integer-type data. When our program is simple, and it is not going to terminate before reaching the last line of the code, or the code is error-free, then we can use the void main().

What Does Void The Main Void Mean?

In the function void main( ), as you must know, void denotes the return type of the main method, this implies that this function does not return any value as void literally means null. In this method, one cannot confirm the status of a program’s execution as the function does not return any value during execution.

Why Not Use Void Main?

Because in C++ main method always return 0. That’s why.

Why Do We Use Void In Int Main?

int main(void) represents that the function takes NO argument. Suppose, if we don’t keep void in the bracket, the function will take any number of arguments. Actually, both seem to be the same but, int main(void) is technically better as it clearly mentions that main can only be called without any parameter.
