When to use the dot operator and when to use the arrow operator in c plus plus?
You use the dot operator when the left side is the name of the object or a reference to an object, and you use the arrow operator when the left side is a pointer to an object. Example: struct foobar x, *p= &x; x.field = p->field; (&x)->field = (*p).field;
Ab plus c equals ab plus ac?
Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.
B plus b plus b plus c plus c plus c plus c equals?
b + b + b + c + c + c + c = 3b + 4c
What is c plus c plus c plus c plus c?
c + c + c + c + c = 5 * c.
What is B plus B plus B plus C plus C plus C?
It is impossible to give any decimal/numeric value if we are not given the values of at least one variable, so the answer is B + B + B + C + C + C.
What is the operator that cannot be overloaded in c plus plus and java?
conditional operator , size of operator , membership operator and scope resulation operator can not be overload in c++
Can the scope resolution operator be overloaded in C plus plus?
No.
What are special operators in c plus plus?
The only "special" operators in C++ are those that cannot be overloaded. That is; the dot member operator (.), pointer to member operator (.*), ternary conditional operator (:?), scope resolution operator (::), sizeof() and typeof().
Which c plus plus operators cannot be overloaded?
1. Member-of operator (.) 2. Pointer-to-member-of operator (.*) 3. Ternary condition operator (?:) 4. Scope resolution operator (::) 5. sizeof operator 6. typeid operator
What is the operator that cannot be overloaded?
There are 5 operators which cannot be overloaded. They are: * .* - class member access operator * :: - scope resolution operator * . - dot operator * ?:: - conditional operator * Sizeof() - operator Note:- This is possible only in C++.
Why ternary operator is not overloaded?
The ternary operator (known as the conditional operator in C++) cannot be overloaded because it is impossible to pass a test operand and two expression operands (either or both of which may be comma-separated) to a function. You can only pass values or references as arguments to a function. Even if it were possible, built-in functions and operators that rely on the conditional operator would likely break. Like all the other operators that cannot be overloaded (sizeof, typeid, ::, . and .*) the results must always be predictable because built-in operators and functions rely on them so heavily.
What is the operator is used to allocate the memory in c plus plus?
calloc operator,malloc operator
Which operator not overloaded in c plus plus?
The if statementex.if (index < 5)printf("Index is less than 5\n");elseprintf("index is greater or equal to 5\n");(You can also replace the "if" with a "?" and the "else" with a "?" -- no, that would be syntax error)
What is the operator of power in c plus plus?
There is no "power" operator in C or C++. You need to the use the math library function pow().
How can you can create a new operator through operator overloading?
You cannot create any new operators in C++. You can only overload the existing ones (although some, such as sizeof, new and delete cannot be overloaded). The only way to create a new operator is to implement it as a standard function with a named identifier. For instance, sqrt() is the standard library function that provides the square root operator, for which no real operator exists.
Example of binaray operator in c plus plus?
+ is an example, one of many, of a binary operator in C or C++ a = b + c; // for usage example
What is the memory management operator in c plus plus?
There is no memory management operator in C++ -- it is an unmanaged language. You use the C++ new operator to allocate memory, and use the C++ delete operator to release previously allocated memory.
