Code Mastery: From Beginner to Expert

Introduction To C++

What is C++?

• C++ is a cross-platform language that can be used to create high performance applications.

• C++ was developed by Bjarne stroustrup as an extension to c language.

• The language was updated by three major times in 2011, 2014 and 2017 to C++ 11, C++ 14, and C++ 17.

Why Use C++?

• C++ is one of the world's most popular programming languages.

• C++ can be found in today's operating systems, Graphical User Interfaces, and embedded systems.

• C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs.

• C++ is portable and can be used to develop applications that can be adapted to multiple platforms.

• C++ is fun and easy to learn!

1. Create Two Programs Hello World and I love pakistan

2. Hide both programs one by one with single line and multi  line comments

Arithmetic operators are used for perform arithmetc operation in this tutorials we will complete study about arithimetic operators after that you will be able to perform basic arithmetic operations

Arithmetic Operators

1. Additon + Add values

2. Multiplication * Multiply values

3. Division / Divide two values

4. Subtraction  - Subtract two values

5. Modulus % Divide two numbers and return remainder

Increment & Decrement Operators

· Incremet Opertor ++ When we use ++ with any number its increases the value for example of the value is 3 but when we user ++3 it will increase 3 to 4.

· Decremen++ operator When we use -- with any number its decreases the value for example of the value is 3 but when we user –3 it will increase 3 to 2.

Solution

#include <iostream>

#include <stdio.h>

Using namespace std;

Int main () {

Int a = 3

cout<<++3;

cout<<a;

cout<<3++;

cout<<a;

cout<<--3;

cout<<a;

cout<<3--;

cout<<a;

}

Note we are print a after increment or decrement because it print out new value on the screen after increment or decrement

Logical Operators & Conditionals Statements

Logical operators are mostly used with conditionals to create different types of logical conditions so that's i making video for logical operators and conditional statements.

Logical Operators

1. = This is an equal operators we used in maths  but talk about computer programming this used as assignment operators means its used to assign values to variables. this is also Assignment operators.

2. == Double Equal operators when we want to equal two values in a computer programming we use this operator this equals to values a = 2; and b = 2; it means 2 == 2.

3. != Exclamatory sign and = equals sign when we both signs at a time this called no t equal to operators means this is used to not equal to two values for examples vale of a = 3 and value of b = 4 so there we can use this a !=

4. && Double & operator its display the answer if you value of both variables i true for example value of a = 2 value b= 2; then this will true for a == b &&  a ==c; this will print out true or yes

5. || Or Operator This is called or operators it print out result if two values are given if there is only a single vale us correct this will print out result.

6. <= Less than or equal to operator this weill print out value is equal to or less than.

7. >= Less than or equal to operator this weill print out value is equal to or greater than.

   Conditional Statements                                                                                                                                                                 

   If condtion is print out result if given condition is true

8. Else if print condition is print out result if if condition is false

9. Else condition is print out result if both conditions are false

Comparison of two values

In this tutorial i am uploading excersie with a comparison operators mean we will comparison two values.

In this video we are creating a rogram that will print out student result on the screen
