Use the Boolean data type
The Boolean data type is a data type, having two values (usually denoted true and false), intended to represent the truth values of logic and Boolean algebra.
It is named after George Boole, who first defined an algebraic system of logic in the mid 19th century.
In C# the code will look like this:
static void Main()
int a = 1;
int b = 2;
bool Check = (a > b); // False
