Before we move towards C language. First we have to know what is Computer programming. And what are some important things which we must know to create any program or any coding for any software or a game.
Computers do “what we tell them to do”, NOT “what we want them to do”.
Computer Programming involves writing instructions and giving them to the computer to complete a task.
An Algorithm is sequence of steps, by which a computer can produce the required outputs from the available inputs. “An effective procedure for solving a class of problems in a finite number of steps.”
Pseudo code is an artificial and informal language that helps programmers develop algorithms. Pseudo code is very similar to everyday English.
A Flowchart is a visual representation of an algorithm. A Flowchart uses easy-to-understand symbols to represent actions on data and the flow of data. Flowcharts aid in breaking down a problem into simple steps.

Algorithm & Pseudo code [ Example 1 ]
Write an algorithm to determine a student’s final grade and indicate whether it is passing or failing. The final grade is calculated as the average of four marks.
Pseudo code:
Input a set of 4 marks
Calculate their average by summing and dividing by 4
if average is below 50
Print “FAIL”
else
Print “PASS”
Algorithm
Step 1: Input M1,M2,M3,M4
Step 2: GRADE ← (M1+M2+M3+M4)/4
Step 3: if (GRADE < 50) then
Print “FAIL”
else
Print “PASS”
endif
