SUMMARY

The modulus operator (%) in C++ is used to determine the remainder of a division operation. In the provided if statement, if (randoms[(x * 3) + y] % 2), it checks whether the element at the index ((x * 3) + y) of the randoms array is odd. If the result of the modulus operation is non-zero, the condition evaluates to true, indicating that the number is odd, and the subsequent code block will execute.

PREREQUISITES
  • Understanding of C++ syntax and operators
  • Familiarity with arrays in C++
  • Basic knowledge of conditional statements in programming
  • Concept of odd and even numbers
NEXT STEPS
  • Study the C++ modulus operator in detail
  • Learn about array indexing and manipulation in C++
  • Explore conditional statements and their applications in C++
  • Investigate the implications of using modulus in performance-critical code
USEFUL FOR

C++ developers, programming students, and anyone looking to understand conditional logic involving the modulus operator in C++.

I have run into an if statement as shown below:

if (randoms[(x * 3) + y] % 2)

I don't really understand what this means.
Thank you for helping!

The [m]%[/m] symbol is the modulus operator, and so the expression [m]n % 2[/m] will be true if n is odd (there is a remainder when dividing by 2) and false if n is even (there is no remainder when dividing by 2).

So, the statement:

[m]if (randoms[(x * 3) + y] % 2)[/m]

Is looking to see if the [m]((x*3) + y)[/m]th element of the [m]randoms[/m] array is odd, and if so, execute some code.
