Not Simple Math

Let’s talk about a bit more complicated math. Sometimes we have a lot of calculations. In C++ (like in math) works the operator precedence, which means that groups of operators have higher priority (precedence) than other ones. For example, we do multiplication and division before addition and subtraction in expressions:


              12
            
int x = 4 + 3 * 3;
cout << x;

The program firstly calculates 3 * 3 (multiplication) and then adds 4.

The expressions in the parentheses have higher precedence than other operators and the calculations in them must be executed first.

C++ provides us with a huge number of useful functions for math tasks. Let’s take a look at the more common ones.

The functions max(x, y) and min(x, y) can be used to find the highest and lowest values of x and y respectively:


              12
            
cout << max(9, 2) << endl;
cout << min(9, 2);
