Test: C++ Operators - Class 7 MCQ

The operator which is having the highest precedence is postfix and lowest is equality.

Because the * operator is having highest precedence, So it is executed first and then the + operator will be executed.
Output:
$ g++ op1.cpp
$ a.out
20

It is a separator here. In C, the value a is stored in c and in d the value b is stored in d because of the bracket.
Output:
$ g++ op3.cpp
$ a.out
5    6

Because of the precedence the pre-increment and post increment operator, we got the output as 749736.
Output:
$ g++ op.cpp
$ a.out
749735

In this program, we are casting the operator to integer, So it is printing as 21 and 10.
Output:
$ g++ op5.cpp
$ a.out
21    10

There are many rights to left associativity operators in C++, which means they are evaluation is done from right to left. Type Cast is one of them. Here is a link of the associativity of operators: https://github.com/MicrosoftDocs/cpp-docs/blob/master/docs/cpp/cpp-built-in-operators-precedence-and-associativity.md

In this operator, if the condition is true means, it will return the first operator, otherwise second operator.

Because the dynamic_cast operator is used to convert from base class to derived class.

j starts with the value 10. j is then incremented to 11. Next, j is added to 100. Finally, j (still containing 11) is added to 999 which yields the result 1010.
Output:
$ g++ op2.cpp
$ a.out
1010

Here the condition is false on conditional operator, so the b value is assigned to c.
Output:
$ g++ op1.cpp
$ a.out
