Hi Hello guys, hope you are doing good, myself Vedakeerthi here and today we are going to see
about programming in computer science.
Programming is the current trend in the IT industry, which is sought out to automate things and
analyse and also helps makes things easier.
Before programming, we need to know about what is the thing we are going to build, or writing a
step by step instruction, this type of script is known as algorithm.
And the algorithm which we implement with rough logic or draft is known as a pseudocode.
For example, we need to program the sum of two numbers, we just write the pseudocode as,
a, b = input from user.
Sum = a+b
Print(sum).
This is how a pseudocode is implemented, the visual or graphical implementation of the structure of
an algorithm is known as a flowchart.
A flowchart is indicated with various symbols which is used to indicate the flow of the algorithm,
these shapes have defined with various properties such as,
1. Oval is used to represent input/output.
2. Rectangle is used to represent the steps
3. The arrows are used to represent the flow of direction from one step to an another
4. Rhombus/ Diamond is used to represent the decision, or the question is written inside the
diamond, and based on the result several arrow goes out of the diamond, each one showing
the direction the process takes for a given answer to the question.
5. Circle is used as a linker, it is an often used symbol, which is used to link a flowchart from a
single page to the flowchart of a different page.
