Section 1- What is mean by programming
We all have a deal to a certain task in daily life and many. we can solve our own, while other which is especially complicated can be solved with the help of a computer, Assume you define a problem that must be solved and you know the steps to be taken to solve it, even you structure you logic perfectly and type solution Brantley in English, the computer will not understand it and it understands 0,1 only and no other symbol and similar to like a switch and it only recognized two phases On and off.
A program is a sequence of instructions that designate how to execute a computation
Therefore the formal definition of programming is taking a task and writing it down in program language that a computer can understand and execute. The activity of telling the computer to do something for us. There are more than 1000 programming language.
Source Code
To communicate real-life problems to computers you need to create a specific type of text called source code or human-readable code that software can read and process to the computer in zero or one form.
Section 2- Why is programming
Now, whatâs your motivation to become a programmer? And as a programmer, you start thinking of yourself as living inside the computer. So youâre a consumer out here.
Youâre clicking on buttons and stuff.
And so as a programmer, youâre going to write code and that code is going to use data, networks, and CPUs, and memory, and then do something for the user.
So weâre trying to change your perspective and sort of pull you into the computer. Well, what are you doing in that computer? Whatâs code? Whatâs software? Whatâs a program?
Well, a program is like a sequence of stored instructions. And the idea is that the computer itself at the lowest level in the hardware is just not that smart. But it has a lot of flexibility in that if we give it the right instructions, it can do amazing things. If we give it right instructions to listen to voice, digitize the voice, and make sense of the voice, then you can write a program that can âhearâ. The computer doesnât hear, the program hears.
The computer makes it so that it can run all the calculations that seems to make it hear, but a human being or actually thousands of human beings made it possible so that you could talk to your phone. And so you can think of, at the far end of this, when youâre building something really brilliant like the ability for a computer to listen to you, you are taking you, and all your creativity, and all the research that youâve done and youâre building something really amazing and put it in the computer. But it is still a stored series of instructions that runs step by step, and someone figured out every single little step that has to happen. And so once we figured this out, we write the instructions carefully and then we give it to somebody. Here is a program that does voice recognition. And if youâre interested in it, I say itâs wonderfully creative.
