Declaring Variables

In C and C++ we first declare the data type of the variable and then declare the name of Variables. A few examples of data types are int, char, float, double, etc.
Python is not “statically typed”. We do not need to declare variables before using them or declare their type. A variable is created the moment we first assign a value to it.

C

// C program to demonstrate
// declaring variable
 
#include <stdio.h>
 
int main()
{
    // Declaring one variable at a time
    int a;
 
    // Declaring more than one variable
    char a, b, c, d;
 
    // Initializing variables 
    float a = 0, b, c;
    b = 1; 
 
    return 0;
}

C++

// C++ program to demonstrate
// declaring variables
 
#include <iostream.h>
 
int main() 
{
    // Declaring one variable at a time 
    int a;
 
    // Declaring more than one variable 
    char a, b, c, d;
 
    // Initializing variables 
    float a = 0, b, c;
    b = 1; 
  
    return 0;
}

Python

# Python program to demonstrate
# creating variables
  
# An integer assignment 
age = 45                     
   
# A floating point 
salary = 1456.8            
   
# A string   
name = "John"             

Comparing Python with C and C++

In the following article, we will compare the 3 most used coding languages from a beginner’s perspective. It will help you to learn basics of all the 3 languages together while saving your time and will also help you to inter shift from one language you know to the other which you don’t. Let’s discuss a brief history of all the 3 languages and then we will move on to the practical learning.
