This article discusses methods to assign values to variables. 

Method 1: Direct Initialisation Method 

• C++
• C
• Java
• Python3
• C#
• Javascript

// C++ code to demonstrate variable assignment

// upon condition using Direct Initialisation Method

#include <bits/stdc++.h>

using namespace std;

int main()

{

    // initialising variables directly

    int a = 5;

    // printing value of a

    cout << "The value of a is: " << a;

}

Output: 

The value of a is: 5

Method 2: Using Conditional Operator (?:)

Below is the syntax in other popular languages.

• C++
• C
• Java
• Python3
• C#
• Javascript

// C++ code to demonstrate variable assignment

// upon condition using Conditional Operator

#include <bits/stdc++.h>

using namespace std;

int main()

{

    // initialising variables using Conditional Operator

    int a = 20 > 10 ? 1 : 0;

    // printing value of a

    cout << "The value of a is: " << a;

}

Output: 

The value of a is: 1

One liner if-else instead of Conditional Operator (?:) in Python

• Python3

# Python 3 code to demonstrate variable assignment

# upon condition using One liner if-else

# initialising variable using Conditional Operator

# a = 20 > 10 ? 1 : 0 is not possible in Python

# Instead there is one liner if-else

a = 1 if 20 > 10 else 0

# printing value of a

print ("The value of a is: " + str(a))

Output: 

The value of a is: 1
