C++ Functions with No Arguments and No return value

In this tutorial you will learn about the C++ Functions with No Arguments and No return value and its application with practical example.

In this tutorial, we will learn to create a C++ program that will use Functions with No Arguments and No return value using C++ programming.

C++ Functions with No Arguments and No return value

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C++ programming topics:

Operators in C++ Programming.
Basic Input and Output function in C++ Programming.
Basic C++ programming.

Arithmetic operations in C++ Programming.
Functions in C++ programming.

What are functions in C++?

In every programming language, there are many types of functions available. There are two major types of functions in C++ programming.

Predefined functions.
User-defined functions.

In user-defined functions there are four types:-

Function with no argument and no return value
Function with no argument but the return value
User-defined Function with argument but no return value

User-defined Function with argument and return value

Algorithm:-

1. Initiating the program.

2. Creating a user defined function with no argument and no return type.

3. Writing the function body code.

4. Write main function code.

5. Call user defined function.

6. End program.

1. Initiating the program.

2. Creating a user defined function with no argument and no return type.

3. Writing the function body code.

4. Write main function code.

5. Call user defined function.

6. End program.

Program using Functions with No Arguments and No return value.

In this program, we will create a function that will print the symbols using a user-defined function with no return type and no arguments. With the help of this program, we can print the “*” of the above function type.

Program Code:-

/* C++ program using Functions with No Arguments and No return value */ 
#include <iostream> 
using namespace std; 
int main() 
{ 
    /* Declaring a user dfined function with no argument and no return type */ 
    void print(); 
    /* Calling that user defined function in main function for printing */ 
    print(); 

    cout<<"\nFunction with  no Arguments and no return type \n"; 
   // print();
    
    return 0;
} 
/* Body of called function in main function */
void print(void)  
    {
        //printing the data on screen
        for (int i=1;i<10;i++) 
        cout<<"* "; 
        cout<<"\n"; 
        
    }

/* C++ program using Functions with No Arguments and No return value */

#include <iostream>

using namespace std;

int main()

{

/* Declaring a user dfined function with no argument and no return type */

void print();

/* Calling that user defined function in main function for printing */

print();

cout<<"\nFunction with no Arguments and no return type \n";

// print();

return 0;

}

/* Body of called function in main function */

void print(void)

{

//printing the data on screen

for (int i=1;i<10;i++)

cout<<"* ";

cout<<"\n";

}

Output:-

Creating the user-defined function with no arguments and no return type.

Body of the user-defined function.

Calling the user-defined function.

Body of the main function of the program.
