Operators in C++ #1730

This video explains the types of c++ operators based on number operands and purpose.

Operators based on operand count #1728

Binary, unary and ternary operator classification is based on number of operands.

Operators for assignment #1734

Here we demonstrate the simple assignment and its variations.

Operators for comparison #1736

Using operators for equality, inequality, greater, lesser, greater or equal, lesser or equal types of comparisons.

Operators for logical use #1739

Testing the use of logical operators like not, and and or operators.

Comma as operator #1741

Comma is a sort of operator which can help form multiple instructions within same instruction.

Bitwise operators #1743

Bit-wise operators work after the given operands are converted to their binary equivalent value.

Typecasting operator #1745

Typecasting or conversion of data type is some times essentially required. This is also a kind of operator in c++

Typecasting while outputting #1747

Type casting is often useful for manipulating display while outputting data.

sizeof operator #1750

Datatype size is found by using the sizeof operator in c++

Simple case of precedence #1752

The order in which operators are applied on operands in an expression can be understood with this example.

Operator precedence with value change within expression #1784

Learning operator precedence case when value changes while evaluating the expression.

Age based discount using ternary operator #2318

Solving age based discount problem with ternary (three operands) operator.

Largest of three numbers using nested ternary operator #2943

A program to demonstrate nesting of ternary operator while finding the largest of three numbers.

Modulus operator for integers #3589

Getting the remainder of an integer division using the modulus operator.

Assignment operator chain #5511

Here we demonstrate the assignment done in a chain fashion.

Multiple value assignment attempts #5571

Here we demonstrate the treatment of precedence between comma, brackets and assignment operator in a multiple value assignment scenario.
