Can we have a function call on left side of an expression?
A function call can appear on the left side of an assignment, but only if the return value of the function is an Object or Variant.
Can a function call statement appear on the left hand side of an assignment operator?
But because in C doesn’t exist the concept of reference object, you can’t directly use a function on the left side of an assignment. It is instead possible in C++ where it exist.
Can we use function on left side of an expression in C and C ++?
In C, it is not possible to have function names on the left side of an expression, but it’s possible in C++.
Does variable assignment go from left to right?
An assignment statement always has a single variable on the left hand side. The value of the expression (which can contain math operators and other variables) on the right of the = sign is stored in the variable on the left.
What is there in right hand side of a variable assignment?
Assignment statements are used to assign objects to locations and can also declare new local variables. The expression on the right hand side must have a return type which is a subtype of the declared type of the destination specified by the left hand side.
What type of function is not a member of a class but has access to the private members of the class?
friend functions
friend functions A friend function is a function that is not a member of a class but has access to the class’s private and protected members.
Which of these can be invoked as a normal function without any object creation?
C++
| Friend Function | Member Function |
|---|---|
| It cannot be called using, can be invoked like a normal function without using an object, defined outside the class scope, etc. | It has its own prototype within the class definition, operates on any object of the class, has access to all members of the class, etc. |
What side does the assignment statement go on?
Which C++ operator is used to assign the value on its right hand side to a variable on its left hand side a ++ b == c d?
Simple Assignment Operator
Simple Assignment Operator (=) : This is the usual assignment operator. Simple-assignment operator assigns its right operand to its left operand. In easy terms, this operator is used to assign the value on the right to the variable on the left.
What is there in right hand side of a variable assignment time expressions waveform elements delays simple expressions?
In which of the following, the right hand side of an assignment is a waveform element? Explanation: The right hand side of a signal assignment statement is a sequence of waveform elements. These elements are having associated time expressions or delays which are generally followed by AFTER keyword.
What are assignment statements in C?
C provides an assignment operator for this purpose, assigning the value to a variable using assignment operator is known as an assignment statement in C. The function of this operator is to assign the values or values in variables on right hand side of an expression to variables on the left hand side.
