What is Programing?
Since this study is entitled “Program Introduction”, it is therefore very important and appropriate to understand what planning really means. Let us first consider the well-known definition of programming. CS201 HANDOUTS
Program: “A program is an accurate sequence of steps to solve a specific problem.” It means that when we say we have a plan, it really means that we know about a complete set of tasks that have to be done in a certain order. The purpose of these activities is to solve a specific problem.
Alan Perlis, a professor at Yale University, states: “It is contrary to modern education to teach children how to plan. What good is a web site if it simply “blends in” with everything else out there? “It is ridiculous about modern education, and it means that modern education does not develop important skills such as planning, editing and attention to detail. on a picnic trip we plan where to go, what to wear, what to take for lunch, how to plan the trip details and have a good time while doing so.
There are no really other basic features of a computer program; everything else we talk about will be the details of a certain process, usually done, to tell a computer what to do. methods are selected because they are found to be suitable for the programmers (people) to use; sometimes chosen because it is easy for the computer to understand them. The first difficult thing about the system is to learn, to relax, and to accept these practices, whether they sound ” to you or not. “ CS201 HANDOUTS
Why Programming is Important?
The question that many people ask is why should we learn to plan when there are so many software and coding codes available for us. The answer is as given by Matthias Felleisen in the book ‘How to design programs.’ CS201 HANDOUTS
The answer consists of two parts. VU All subjects handouts
First, it is quite true that traditional methods of planning are useful to a few people. But, editing as we writers understand is useful for everyone: a managing secretary who uses spreadsheets and a high-tech designer. In other words, we have a broader perspective on mental planning than ever before. We explain our point of view in a moment.
Second, we teach our planning approach to technology based on the goal of small interventions. Therefore, our programing approach teaches problem analysis and problem-solving skills without having to go beyond traditional program documentation and tools.
So learning to plan is important because it develops analytical skills and problem solving skills. It is a work of art and gives us a way to express unseen ideas. So planning is fun and is much more than a job study skill. By designing programs, we learn many important skills throughout the work.

Arrays
The same members are the type of data structure. We use the same members to store multiple values for the same type of data. For languages C, C ++ and FORTRAN, arrays the same data type i.e. every element of the array is of the same data type. There may be an array of integers, an array of letters, an array of decimal numbers and so on. We cannot have elements of different kinds in a same array.
Arrays are like that used for dynamic integration of the same type of data. We wrote small works about it too we have done some tests eg, when we want to keep the age of our classmates. Then instead of using different alternatives for each student, the same members were hired to be retained age of students. Then trick or access the same individual elements, a technical array index was used.
One important point to remember is that list indicators start at 0. Suppose our name of the same members is 10 inches, the first part of it will be a [0] while the latter will be [9]. Some languages like Fortran do base on 1 indexing. Because of this 0-based index of the same members in language C, the program editors prefer starting loops from 0. VU All subjects handouts
