sum of two numbers using while loop in c code example

Example 1: adding two numbers in python

# This program adds two numbers

num1 = 1.5
num2 = 6.3

# Add two numbers
sum = float(num1) + float(num2)

# Display the sum
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

Example 2: how to add a number after each number in an array with a for loop in C++

#include<iostream>
	using namespace std;

	int main()
	{
		int a[4];
		int i;

		for ( i = 0; i < 4; i++ )
			a[i] = 0;
		for ( i = 0; i < 4; i++ )
			cout << a[i] << '\n';
		return 0;
	}
