The basic idea behind the program is that it will randomly generate two numbers within a range that the user selectsand then ask the user what the answer is, when you apply some operator. If the user types in the correct answer, the program will congratulate the user.

If the user types in the wrong answer, the program will encouragingly inform the user that the answer is not correct, and will then inform the user of what the correct answer is. Four example transcripts of how the program works appears below — your program's output should be the same, but can differ in whitespace i. User input is given in bold. Make sure that you display the correct operator in your output! Welcome to The Quiz Program! Thank you for using this program - have a nice day!

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. It's not exactly possible to google its use without knowing the proper name for it. In computer programming languages, the equals sign typically denotes either a boolean operator to test equality of values e. It's the assignment operator in Pascal and is often used in proofs and pseudo-code. It is done to allow for interpreted-like creation of variables in a compiled language.

Another interpretation from outside the world of programming languages comes from Wolfram Mathworldet al:. If A and B are equal by definition i.

Bringing clarity to what is being set to where as opposed to the logical operator of equivalence. Assignments typically allow a variable to hold different values at different times during its life-span and scope.

However, some languages primarily strictly functional do not allow that kind of "destructive" reassignment, as it might imply changes of non-local state. The purpose is to enforce referential transparency, i. The strange convention of using equals for assignment and double-equals for comparison was started with the C language. Learn more.

This is old pascal syntax for the assignment operator. Master James Master James 1, 11 11 silver badges 16 16 bronze badges. For VB. Near Near 14 14 bronze badges.An assignment operator is the operator used to assign a new value to a variable, property, event or indexer element in C programming language. Assignment operators can also be used for logical operations such as bitwise logical operations or operations on integral operands and Boolean operands.

This allows the assignment operator to be used with those types. In Can expression using an assignment operator might be "x op y", where x and y are operands and "op" represents the operator.

The result is its return value. The other assignment operators that perform indicated operation on the two operands and assign a resulting value to the left operand are called compound assignment operators.

These include:. Toggle navigation Menu. Home Dictionary Tags Development. Assignment Operator. Definition - What does Assignment Operator mean? Overloading a binary operator implicitly overloads its corresponding assignment operator if any. The meaning of the operator symbol used depends on the type of the operands. Assignment operators are right-associative, which means they are grouped from right to left. The assignment operator expects the type of both the left- and right-hand side to be the same for successful assignment.

Special Operators: Assignment Operator

Note: henceforth, I will identify the operators by putting them between double quotes. These quotation marks are not to be taken as part of the operator. This is an unfortunate choice for assignment.

Here is a typical use:. Suppose the lhs is a floating point type generically, I will refer to them as float and the lhs is an integer type int. For the compiler to make the assignment, it will have to chop off the fractional part of the float. Thus, information is lost. Sometimes you desire this result and you want to suppress the warning that would normally be issued.

A cast is a way to tell the compiler that you know what you are doing. If it is the case that the compiler can convert one type to another without losing information, then a type promotion is done. Assigning an int to a float, for example, is not a problem; the int is promoted to a float without loss of information no fractional part thrown out.

If you use any of these operators on two operands of the same type, the result is that type. Mixing the types causes automatic promotion. Modulo arithmetic is only allowed with integer types. When an int int-type is divided by another int, the result is an int.

Simple you say? Yes, but that can trip you up and cause your program to give erroneous results. Let me show you in this example. Suppose you write a program to convert Fahrenheit to Celcius. See the programin module 2. It must contain an assignment statement along the lines of. Regardless of the value of fahr that is used, celc will be assigned 0.

How is that? Both of the literal constants 5 and 9 are stored by the compiler as integers.There are those that simply cannot be overloaded, and then there are those that must be overloaded as member functions of the class; they cannot be nonmember functions. The assignment operator can be defined to assign any type to an object of your user-defined type. But we most often think of this operator as assigning an object of some type to an object of the same type.

This is referred to as copy assignment. Copy assignment is very important to define correctly. However, it may not be necessary to define it since once again, the compiler will generate a definition for the copy assignment operator. But as it is with the compiler generated copy constructor, it will be a shallow copy: every member of the class is copied from the source to the target without consideration to pointer problems.

If your class has no pointer members, then the shallow copy works just fine. Here is how you would define it. The order of evaluation of assignment operators is right to left.

In assigning h to g, a reference to g is returned. This is then assigned to f. Special Operators: Assignment Operator. Variable Declarations. Reserved Words. Assignment and Arithmetic.

The manual system needs to be replaced with the computerized system to give more convenience to the student and the lecturer.

When students hand over their assignment the operator will keep the records of the submission details. Emails will be sent to the students to verify their submission. The same goes for the marked and collected assignment. In addition, the lecturer will be informed to check the submission records of the students. By doing this, the assignment is always kept in safe condition after the submission. The proposed system also helps lecturer to keep track of their student submission.

The lecturer can check the time of submission and enable the student to collect their assignment after being marked. This system will improve the management of student assignment at the institution. An online assignment handling is a system contained within the Module virtual learning environment.

Extension requests are an integral part of the system. Universities, Polytechnics and colleges of education are considered the main provider of knowledge in various fields.

Various courses of studies are taught in institutions, covering several fields including applied Sciences, Math, Computer, Human Resource, and Accounting. Most courses at universities consist of theoretical as well as practical subject matter. To evaluate the level of understanding and degree of comprehension among students, assignments are often given.

Assignments are submitted by students either individually or in groups.

Assignment management involves collecting, marking, and redistributing to students. Tregobov breaks the process down into four stages: submission, recording, marking, and return. With traditional assignment submission system, lots of problems arise especially when the students have to submit the answers of the assignment to the lecturer.
