cout<<"1. Addition\n";
cout<<"2. Subtraction\n";
cout<<"3. Multiply\n";
cout<<"4. Division\n";
cout<<"Enter option: "
cin>>option;

switch(option) {
case 1:
result=firstnumber+secondnumber;
cout<<"Result of Addition is "<<result;
case 2:
result=firstnumber-secondnumber;
cout<<"Result of Subtraction is "<<result;
case 3:
result=firstnumber*secondnumber;
cout<<"Result of Multiply is "<<result;

Hello guys,

Today I am going to start an HTML. Here I will explain to you in every detail. How to start HTML and see the output of the Html.

The full form of the Html is HyperText Markup Language.
By using HTML elements we can create a HTML pages.
All HTML elements are designed in < > tags.

in the above picture you can see there are many HTML elements are used. and the above example is divided into 3 part
Section 1: Main Section
Section 2: Head section

for any HTML code, you have to divide code into 3 parts.

For main section <html> tag used.
For head section <head> tag used.
For body section <body> tag used.

4. Html tag come in pairs. means there will be an open tag and closing tag.
In the above picture at line number 1 <html> tag open and it closed at line 10 with </html> tag.
All HTML tag closed by forward-slash(/). same as head tag open at line no 2 and closed at line no 4.
In the body section there Heading tag.
