What is a Programming language?
Think about how we communicate with people around us? Language is our primary means of
communication for all human interactions. Similarly, we can interact with computers via a language
that computers understand. This language is known as programming language.
Using programming languages, we can provide instructions to a computer to perform a set of
activities. These sets of instructions are called programs. Like any other language that has grammar,
programming languages have syntax. Some of the most frequently used programming language are
C, C++, Java, JavaScript, R, and Python.
The first programmer or the first person to rite our modern
understanding of a program was Ada Lovelace.
About Syntax
Syntax is the set of rules for writing a programming language. It is like the spelling and grammar of
the language that define its structure.
There are hundreds of programming languages used around the world and new ones are getting developed
all the time. Every programming language has its own syntax. But all programming languages have one
common thing, they are eventually converted into a language that the computer will understand.
Algorithm Step 1 Start
Representing the data in a sequential way (step by step)
is called algorithm. Step 2 Take the fruits
Example: Write the step to make the fruit shake.
Step 3 Take 2 bottles of milk
Step 4 Cut the fruits & put it in the blender
Step 5 Grind with the blender
Step 6 Pour the milk in the blender
Features of an Algorithm Step 7 Enjoy your yummy fruit juice
l The algorithms should have clear explanations for each step.
l Algorithms must be independent of programming language.
l After a limited number of steps, algorithms must be stopped.
l An algorithm must have a specific well-defined output and zero or more well-defined inputs.
