a+b in this expression a and b is operands and + is an operator

• Unary (a):-Unary operators are the operators that perform operations on a single operand to produce a new value
• Binary (a+b):-A binary operator is an operator that operates on two operands and manipulates them to return a result
• Ternary (a+b+c+d):-A Ternary operator is an operator that operates on three or more operands and manipulates them to return a result

• + (Plus)
• - (Minus)
• * (Multiply)
• / (Divide)
• % (Mod)

• > (Greater then)
• < (Less then)
• >= (Greater then equal to)
• <= (Less then equal to)
• = (Equal to)
• == (Equal equals)

• && (And):-The logical AND operator is an operator that performs a logical conjunction on two statements. It only yields a value of “true” when both statements are true. If one of the two statements is false, then the logical AND operator yields a “false” value.
• || (Or):-The OR operator is a Boolean operator which would return the value TRUE if one or more conditions is true
• ! (Not):-An operation on logical values that changes true to false, and false to true

• += (Plus equal)
• -= (Minus equal)
• *= (Multiply equal)
• /= (Divide equal)
• %= (Mod equal)

if we write a=a+b then we will also write this expression a+=b it means same

• >> (Right Shift)
• << (Left Shift)
• ^ (Power)
• ~ (Destructor)

• sizeof:-Sizeof is a much-used operator in the C. It is a compile-time unary operator which can be used to compute the size of its operand

#include<iostream.h>
#include<conio.h>
class aptech
{
public:
sizeofexample()
{
int a;
cout<<sizeof(a);
}
};
void main()
{
aptech ap;
clrscr();
ap.sizeofexample();
getch();
}

• ? (If)and(else):-The conditional operator is also known as a ternary operator. The conditional statements are the decision-making statements which depends upon the output of the expression. It is represented by two symbols, i.e., '?' and ':'.

#include<iostream.h>
#include<conio.h>
class aptech
{
public:
conditionalexample()
{
int age;
cout<<"Enter age=";
cin>>age;
cout<<age>=18?"Eligible":"Not Eligible";
//cout<<age>=18?1:0;
}
}
void main()
{
aptech ap;
clrscr();
ap.conditionalexample();
getch();
}

• ++ (Increment)and -- (Decrement):-Increment Operator is used to increase the value of the operand by 1 whereas the Decrement Operator is used to decrease the value of the operand by 1.

Increment and Decrement operators is basically two of types

• Prefix (++a):-The prefix increment operator (++) adds one to its operand before print
• Postfix (a++):-The prefix increment operator (++) adds one to its operand after print
