Arithmetic Operators in C/C++

An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. Operators are the foundation of any programming language. Thus the functionality of C/C++ programming language is incomplete without the use of operators. We can define operators as symbols that help us to perform specific mathematical and logical computations on operands. In other words, we can say that an operator operates the operands. 


Arithmetic Operators

It includes basic arithmetic operations like addition, subtraction, multiplication, division, modulus operations, increment, and decrement.

The Arithmetic Operators in C and C++ include:

  1.  + (Addition) – This operator is used to add two operands.
  2. – (Subtraction) – Subtract two operands.
  3. * (Multiplication) – Multiply two operands.
  4. / (Division) – Divide two operands and gives the quotient as the answer.
  5. % (Modulus operation) – Find the remains of two integers and gives the remainder after the division.
  6. ++ (Increment) – Used to increment an operand.
  7. — (Decrement) – Used to decrement an operand.
Example of Arithmetic Operators in C
#include<stdio.h>
int main()
{
int a=10, b=7;
printf("Welcome to DataFlair tutorials!\n\n");
printf("The Addition of %d and %d is: %d\n",a,b,a+b);
printf("The Subtraction of %d and %d is: %d\n",a,b,a-b);
printf("The Multiplication of %d and %d is: %d\n",a,b,a*b);
printf("The Division of %d and %d is: %d\n",a,b,a/b);
printf("The Modulus operation of %d and %d is: %d\n",a,b,a%b);
printf("The Incremented value ++a is: %d\n",++a);
printf("The Decremented value --b is: %d\n",--b);
return 0;
}
Example of Arithmetic Operators in C++

Here is a code in C++ which illustrates all the basic arithmetic operators:

#include <iostream>
using namespace std;
int main()
{
cout<<"Welcome to DataFlair tutorials!\n\n"<<endl<<endl;
int a = 10, b = 7;
cout<<"The Addition of "<< a << " and " << b << " are: " << a + b <<endl;
cout<<"The Subtraction of "<< a << " and " << b << " are: " << a - b <<endl;
cout<<"The Multiplication of "<< a << " and " << b << " are: " << a * b <<endl;
cout<<"The Division of "<< a << " and " << b << " are: " << a / b <<endl;
cout<<"The Modulus operation between "<< a << " and " << b << " is: " << a % b <<endl;
cout<<"The Incremented value ++a is: "<< ++a <<endl;
cout<<"The Decremented value --a is: "<< --a <<endl;
return 0;
}

Difference between net platform and dot net framework...

Difference between net platform and dot net framework... .net platform supports programming languages that are .net compatible. It is the platform using which we can build and develop the applications. .net framework is the engine inside the .net platform which actually compiles and produces the executable code. .net framework contains CLR(Common Language Runtime) and FCL(Framework Class Library) using which it produces the platform independent codes. What is the .NET Framework? The Microsoft .NET Framework is a platform for building, deploying, and running Web Services and applications. It provides a highly productive, standards-based, multi-language environment for integrating existing investments with next-generation applications and services as well as the agility to solve the challenges of deployment and operation of Internet-scale applications. The .NET Framework consists of three main parts: the common language runtime, a hierarchical set of unified class librari...

Standard and Formatted Input / Output in C++

The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming. C++ I/O occurs in streams, which are sequences of bytes. If bytes flow from a device like a keyboard, a disk drive, or a network connection etc. to main memory, this is called   input operation   and if bytes flow from main memory to a device like a display screen, a printer, a disk drive, or a network connection, etc., this is called   output operation . Standard Input and Output in C++ is done through the use of  streams . Streams are generic places to send or receive data. In C++, I/O is done through classes and objects defined in the header file  <iostream> .  iostream  stands for standard input-output stream. This header file contains definitions to objects like  cin ,  cout , etc. /O Library Header Files There are...
