How to have both functions called with logical AND operator (&&) c++
c++, logical-and, logical-operators
Solution
In C (and included in C++ by default) the `&&` operator is `short-circuiting`. This means that as soon as the condition is deemed false the other operand is not evalulated. It allows us to do things like `if(ptr && ptr->value == 10)` without having to do the pointer validity check before the value check in a separate if statement.
If you want to run both functions, run both functions and save off the results:
bool b = foo();
if(foobar() && b)
{
// Stuff
}
Problem
Let's say I had two functions and a variable, ``` int number; bool foo (void); bool footoo (void); ``` And in each of these functions, some logic with the variable `number` takes place, such as: ``` number++; return(rand()%2); ``` And then I call them like so: ``` if (foo() && footoo()) { cout << "Two foo true!" } ``` Why aren't both functions being called and how can I guarantee both functions are called and increment `number`, regardless of return value?
