• Do you know: •Using Programming, you can create your own games, your personal blog/profile page, a social networking sites like Facebook, search engines, an e-commerce platforms • The backbones of today's technology companies like Google, Facebook, Microsoft, Apple, Amazon, and many others, are giant computer programs written by a collaboration of thousands of skilled programmers. Computer Programmers are paid extremely well almost all across the world. Top programmers in Silicon Valley make millions of dollars every year. • What is the need of computer language? The answer is communication with the machine i.e. the computer. I am teaching programming means I am communicating with you people, if you want to ask any question, any query want to pass, then you should communicate with me, I am communicating with my bike or car when I just want to travel from one location to another location! Communicating with my mother and communicating with my father, there is communication means something you are getting, so if one person want to communicate with the another person, generally he have to share information, Information is nothing but passing instructions. In general communication we are using general languages like English, Hindi, Telugu, all these languages we use, but now here the person want to communicate with machine. Any electronic machine is considered computer, the person want to communicate with the machine. Sir Question, why the person want to communicate with the machine? Simply consider it is I am asking the question what is the 31, everyone can answer easily, its 6, simple calculation. Now, if my next question is what is 99, no one can answer, because now operation is a Complex operation. Now instead of doing Complex operations manually, it is better to interact with electronic device, example take calculator, using calculator whatever the number you give as an input fraction of second will get down, so for complex operations, it is better to interact with electronic device. I want to communicate with you, I am teaching something to you, why I amप्रोग्राम स्ट्रक्चर using English language? Because you people understand English language very Similarly, computer persons need pass instructions understandable language, only what computer understands L.e. binary language. understands binary language. Can anyone pass instructions in binary We cannot write applications write binary language, very complex. That's why first have learn programming language properly, write programs using programming language, many examples C. C+++, java.net, programming languages are high languages. First you have learn programming language, the rales, how define instruction set, how write programs, everything you should learn perfectly, once you perfect programming language, only then can write programs. You should be why? The reason suppose am perfect English language then only can interact you English, in same way you communicate with the computer using first you should learn perfectly Clanguage, after learning Clanguage perfectly, you will perfect writing • Writing program is instructions, is written any high level language, but cannot this high level language understand, high level language is the user, its user understandable the user, but understands only binary language i.e, and zeros, then what we should do, how we convert into binary language, for this is called, program name compiler program or software, we should take care what program have written, responsible for conversion compilers already available, so what will do, will convert all these instructions into binary instructions, called code, once machine code ready, you can pass an input the computer so that will produce the output, this actually the process communication with the • Why communicating? To perform operations an easy way. Suppose, available, you just want withdraw some amount of money from your it's a long process, visit the bank, then so much process complete, finally get the right, suppose availability is there, within minutes you can withdraw the wherever you are this world, machines always makes our task very easy, so you communicating with Machines. But, communication not allowed because we pass instructions language. You have to learn one language, after learning language, you writing programs and then converting into instruction set using compiler then communication, so after writing programs, compilation, so we are using • you want to interact with the machine, no need become programmer. Consider, you want perform transaction from the ATM, necessary become C? a java programmer? net programmer? No, required! As an end user also you communicate machine, how? possible. am not programmer but want interact with the machine a particular task, what we should do? Now, with programmer, one more person present, the person is called end user, or the client, company is always waiting clients, working for end users, we developing applications for end only, programmers provides interfaces in office. Sir, what interface? Just working like a mediator between programmer and end user and as well background application. Interface means without having background details we can perform our Now, consider user want perform transaction, he communicate interfaces, how? Whenever end user enters into this ATM centre, on the message ng
