1. In mathematics and sometimes in computer programming, an operator is a character that represents an action, as for example x is an arithmetic operator that represents multiplication. In computer programs, one of the most familiar sets of operators, the Boolean operators, is used to work with true/false values.
There are three types of operator that programmers use: arithmetic operators. relational operators. logical operators.
An operator is used to manipulate individual data items and return a result. These items are called operands or arguments. Operators are represented by special characters or by keywords.
I encountered something that I can't understand.
I have this code:
cout << "f1 * f1 + f2 * f1 - f1 / f2 is: "<< f1 * f1 + f2 * f1 - f1 / f2 << endl;
All the "f"s are objects, and all the operators are overloaded.
The weird this is that the first computation is of the / operator,
then the second * and then the first *; after that, the operator + and at last, operator -.
So basically, the / and * worked from right to left,
and the + and - operators worked from left to right.
I made another test... I checked this code:
cout << "f1 * f1 / f2 is: " << f1 * f1 / f2 << endl;
Now, the first operator was * and only then operator /.
So now, it worked from left to right.
Can someone help me understand why is there difference in the directions?
