How do you get a unique number between two numbers?

A standard example is the Cantor pairing function N×N→N, given by: π(a,b)=12(a+b)(a+b+1)+b. if the numbers are a and b, take 2a3b. This method works for any number of numbers (just take different primes as the bases), and all the numbers are distinct.

What is it called when you combine two numbers?

When two numbers are added together, the result is called a sum. The two numbers being added together are called addends.

How do you put 2 numbers together in C++?

In this program, user is asked to enter two integers. These two integers are stored in variables firstNumber and secondNumber respectively. Then, the variables firstNumber and secondNumber are added using + operator and stored in sumOfTwoNumbers variable. Finally, sumOfTwoNumbers is displayed on the screen.

How do you use modulo to get digits?

To find last digit of a number, we use modulo operator \%. When modulo divided by 10 returns its last digit. To finding first digit of a number is little expensive than last digit. To find first digit of a number we divide the given number by 10 until number is greater than 10.

What makes the number 2 unique?

The number 2 is called the “oddest” even prime number. 2 is a unique even prime number because all even numbers are divisible by 2. But any number apart from 2 that is divisible by 2 is not a prime number.

Why is the number one unique number?

1 is called a unique number because it is neither a prime number nor a composite number. It has only one factor, i.e, the number itself; and to be a composite number also the number must have two factors, i.e, 1 and the number; and a prime number also must have more than two factors.

What is addition called?

sum
Addition sentence The numbers that are added are called addends and the answer to addition is called the sum. In an addition sentence, the addends are added to get the sum.

How do you join 2 numbers?

How to concatenate two Integer values into one?

1. Convert both numbers to string.
2. Concatenate both strings into one, as this is comparatively easy.
3. Convert this concatenated string back to integer.

How do you add double and int in C++?

Because this is an int divided by a double, the compiler handles this by converting the int into a double. Thus, the result of b / d is a double. The next thing that C++ does is add a to the result of b / d . This is an int added to a double, so it converts the int to a double and adds, resulting in a double.

How do you extract the last two digits of a number?

We can easily find the last two digit of a number using modules 100.

1. Let N be the input.
2. If N is a one-digit number, simply print N and terminate the program.
3. Let temp = N \% 100.
4. If temp is greater than 9, simply print temp.
5. If temp is less than or equal to 9, then it implies that the second last digit of N is 0.

How do you combine two numbers together?

If the numbers you are trying to combine are positive integers you can use pairing Functions. Pairing function creates a unique number from two. It is also a reversible function.

How to add two numbers without using arithmetic operators in C?

Add two numbers without using arithmetic operators. Write a function Add() that returns sum of two integers. The function should not use any of the arithmetic operators (+, ++, –, -, .. etc). Sum of two bits can be obtained by performing XOR (^) of the two bits. Carry bit can be obtained by performing AND (&) of two bits.

How to write a function that returns sum of two integers?

Write a function Add () that returns sum of two integers. The function should not use any of the arithmetic operators (+, ++, –, -, .. etc). Sum of two bits can be obtained by performing XOR (^) of the two bits. Carry bit can be obtained by performing AND (&) of two bits.

How to transform X into Y using four operations?

4*2 = 8 2. 8-1 = 7 Input : x = 2, y = 5 Output : 4 We can transform x into y using following four operations. 1. 2*2 = 4 2. 4-1 = 3 3. 3*2 = 6 4. 6-1 = 5 Answer = 4 Note that other sequences of two operations would take more operations.
