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.

Question

Use the friend function to rewrite the operator overloading of operator +

#include<iostream>
using namespace std;
class Complex {
private:
int real, imag;
Complex (int r = 0, int i = 0) {real = r; imag i;}
// This is automatically called when '+' is used with
// between two Complex objects
Complex operator+ (Complex const &obj) {
public:
}
Complex res;
res.real = real + obj.real;
res.imag imag + obj.imag;
return res;
}
void print () { cout << real << " + i" << imag << '\n'; }
};
int main()
{
Complex c1(10, 5), c2(2, 4);
Complex c3 = c1 + c2;
c3.print();

Use Clojure: a. See attached picture. b. In Clojure (like other functional programming languages) functions and variables are treated identically. This means a function may easily take another function as an argument, and/or return a function. Write a function swap-arg-order which takes a function (of two arguments) as an argument returns another function that does the same thing, but expects its two arguments in the opposite order.That is, for example• given the division function / which divides the first argument by the second (so (/ 3 6) returns the number 1/2), the following expression should evaluate to 2((swap-arg-order /) 3 6)• given the function list-longer-than? from above, the following expression should evaluate to true((swap-arg-order list-longer-than?) '(1 2 3) 2) c. Define a higher order function g so the following expression evaluates to true:(= 100 (g (fn [n] (* n n))))

Can you write a C++ program for this: Create a class of function objects called StartsWith that satisfies the following specification: when initialized with character c, an object of this class behaves as a unary predicate that determines if its stringargument starts with c. For example, StartsWith(’a’) is a functionobject that can be used as a unary predicate to determine if a string startswith an a. So StartsWith(’a’)("alice") would return true butStartsWith(’a’)("bob") would return false. The function objectsshould return false when called on an empty string. Test your functionobjects by using one of them together with the STL algorithm count_ifto count the number of strings that start with some letter in some vectorof strings
For each of the following expressions, write functions f1, f2, f3, and f4 such that the evaluation of each expression succeeds, without causing an error. Be sure to use lambdas in your function definition instead of nested def statements. Each function should have a one line solution. f1 takes in nothing and returns 3. f2 takes in nothing and returns a function that takes in nothing and returns 3. f3 takes in nothing and returns a function that takes in 1 value and returns that same value. f4 takes in nothing and returns a function. This function takes in nothing and returns another function. This next function takes in a value and returns yet another function. This final function takes in nothing and returns the value passed into the previous function (if this explanation is confusing, have a look at the doctest, and it might be more clear). def f1(): >>> f1() 3 |||||| "*** YOUR CODE HERE ***" def f2(): |||||| >>> f2() () 3 |||||| "*** YOUR CODE HERE ***" def f3(): |||||| >>> f3() (3)…
