What Is Relational Operators...?
Relational Operators
There are following relational operators supported by C++ language
Assume variable A holds 10 and variable B holds 20, then:
| Operator | Description | Example |
|---|---|---|
| == | Checks if the values of two operands are equal or not, if yes then condition becomes true. | (A == B) is not true. |
| != | Checks if the values of two operands are equal or not, if values are not equal then condition becomes true. | (A != B) is true. |
| > | Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. | (A > B) is not true. |
| < | Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. | (A < B) is true. |
| >= | Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true. | (A >= B) is not true. |
| <= | Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. | (A <= B) is true. |
What is Arithmetic Operators
There are following arithmetic operators supported by C++ language:
Assume variable A holds 10 and variable B holds 20, then:
| Operator | Description | Example |
|---|---|---|
| + | Adds two operands | A + B will give 30 |
| - | Subtracts second operand from the first | A - B will give -10 |
| * | Multiplies both operands | A * B will give 200 |
| / | Divides numerator by de-numerator | B / A will give 2 |
| % | Modulus Operator and remainder of after an integer division | B % A will give 0 |
| ++ | Increment operator, increases integer value by one | A++ will give 11 |
| -- | Decrement operator, decreases integer value by one | A-- will give 9 |
What is Operators..
An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. C++ is rich in built-in operators and provides the following types of operators:
- Arithmetic Operators
- Relational Operators
- Logical Operators
- Bitwise Operators
- Assignment Operators
- Misc Operators
This chapter will examine the arithmetic, relational, logical, bitwise, assignment and other operators one by one.

Object Code....
Object code is produced when an interpreter or a compiler translates source code into recognizable and executable machine code.
Object code is a set of instruction codes that is understood by a computer at the lowest hardware level. Object code is usually produced by a compiler that reads some higher level computer language source instructions and translates them into equivalent machine language instructions... As Like (0,1)
Source Code...
Source code is the fundamental component of a computer Program that is created by a programmer. It can be read and easily understood by a human being. When a programmer types a sequence of C Language statements into Windows Notepad, for example, and saves the sequence as a text file, the text file is said to contain the source code.
It is Source Code......! #include<iostream>
It is Source Code......! #include<iostream>
#include<conio.h>
int caal(int);
using namespace std;
int main()
{
int n,s;
cout<<"Enter valu =";
cin>>n;
s=caal(n);
cout<<s;
return 0;
}
Programming Language.....
A programming language is a formal language that specifies a set of instructions that can be used to produce various kinds of output. Programming languages generally consist of for a computer. Programming languages can be used to create programs that implement specific algorithms.
What Is C++ Programming Language ...?
C++ is an object-oriented programming (OOP) language that is viewed by many as the best language for creating large-scale applications. C++ is a superset of the C language.
A related programming language, Java, is based on C++ but optimized for the distribution of program objects in a network such as the Internet. Java is somewhat simpler and easier to learn than C++ and has characteristics that give it other advantages over C++. However, both languages require a considerable amount of study.
