Write a C/C++ program that asks the user for three integer marks. These are the student marks out of 25 for class tests. Subsequently the program should ask the user for a big test mark out of 50. The final mark is calculated with 50% class tests and 50% test mark. Test all values for validity. If a value is invalid, a message should be displayed, and the user should be repeatedly given chance to correct the input. The program should display the final mark, as well as the symbol of the student (see Table 1.2). The program should repeat until the user enters “-1” for the first class test. After the user has entered “-1”, the program should display a summary of the marks, i.e. the average final mark, highest final mark, and lowest final mark. The program also displays the number of students that pass (mark>=50), pass with distinction (mark>=75), and the number of students that fail (mark<50) See Figure 1.2 for example output
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.
