Print Function in C, C++, and Python

In this article, the task is to observe the behavior of the print function in C, C++, and Python. Print function is used to display content on the screen.

Approach: 

• Some characters are stored in integer value inside printf function.
• Printing the value as well as the count of the characters.
• Illustrating the different use of printf().

Below is the C program printing the inside printf:

C

// C program printing inside printf()

#include <stdio.h>

// Driver Code
int main()
{
    // Stores no of characters printed by printf
    int val = printf("GeeksForGeeks\n");

    // Print the count of characters
    printf("Int printf(\"GeeksForGeeks\\n \") = %d\n", val);


    return 0;
}

Output

GeeksForGeeks
Int printf("GeeksForGeeks\n ") = 14

Below is the C++ program printing inside cout:

C++

// C++ program printing inside cout

#include <iostream>
using namespace std;

// Driver Code
int main()
{

    // Store no of characters printed by printf
    int value = printf("GeeksForGeeks\n");

    // Prints the count of the characters
    cout << "Integer printf(\"GeeksForGeeks\\n\") = "
         << value << endl;
}

Output

GeeksForGeeks
Integer printf("GeeksForGeeks\n") = 14

Explanation:

• In both the above code, printf returns the number of character it has printed successfully.
• “GeeksForGeeks\n” have 14 characters hence it will print 14.

Below is the python program illustrating print():

Python3

# Python program illustrating print()

# Storing value
value=print("GeeksForGeeks\n")

# Printing value
print(value)

Output

GeeksForGeeks

None

Explanation: In python3, Print function never returns anything that’s why it is returning None.
