Hello guys, are you interested to write programs in C language. I will tell you the topics which are essential to make programs easily in C language. You’ll be able to create any program after knowing some important topics in C language. Your programming skills will surely enhance after understanding the core of C. And it will also help you to make interesting programs that you want.
Top List of Essential Topics of C
1. Data type
Data types are the basic blocks of any language. Data types tell that what type of data is to be stored in a variable. In any programming language data is the main focus. So, at first, we must know about the data types and should use the data according to the requirements. C provides a large variety of data types. There are two types of data types and that are: -
Primary data type
- int: -
Loops are very important in C language because with the help of loops code is minimized to write. Loop facilitate us to repeat a code segment again and again until the condition becomes false. Three loops are there in C language
- For loop: - Mostly - used, accepts three parameters and that are initialization, condition, and increment. There is one more parameter that is decrement but it only executes when the condition is true until the condition becomes false.
- While loop: - It accepts one parameter and there is a condition that it executes only when the condition is true.
- Do- While loop: - It also accepts one parameter and that is a condition but it executes at least once whether the condition is true or false.
The above given are the three loops which are used to repeat the task as per the requirement. By understanding loops appropriately, you can make diverse patterns and can apply the right logic at the right place.
Making functions is very informal in C language. Functions can call from anywhere in the program after writing once. Functions help to split the problem into parts. For a particular part of a problem, we can make a function for that. Functions make programming languages modest. Functions can be called by two methods and that is Call by value and Call by reference.
An array is used when we are required to work with a group of homogeneous data. We can store the same type of data under the same name. Arrays are very useful when we are required data in a large amount.
Pointers provide dynamic memory allocation. This is a significant portion when we are making a program or application where memory is the main focus, we can say where all tasks are done with memory interaction and lot of chances to have a problem because of memory. To manage memory there are functions provided by Java and that is malloc (), calloc (), free ().
A group of characters is called String. We can say that String is a one-dimensional array of characters. The string is also important because many methods are there related to strings which make work easy like to copy a string We can use strings (). Strings are beneficial when we have to make a program in which there are a large number of strings like make a program to show a list of programmers.
A structure is also a kind of array but it can store the data of different data types under the same name. We can use structure when we need to save a record of anything. The record may be of anything like a record of books, the record of students etc. The union is much more similar to structure. It also stores the data items of a different kind but at the same memory location.
C has a rich collection of a lot of libraries. Libraries are the most beautiful feature of the C programming language. Libraries are a collection of functions and declarations. Some libraries are frequently used like stdio (Standard Input Output), conio (Console Input Output) math header files which are in several libraries.
10. File I/O
When you increase your step in C programming towards complexity then Must be aware of File I/O. By using this anyone can make text or binary file for their database. We deal with files in this section. Many functions are there by which you can manipulate your files.
So, these are some essentials topics of C language which one should entirely comprehend while learning C language course. For an advanced level of training joining an ideal training center is very signifying. A good institute can provide you industry relevant training with appropriate facilities which assist an aspirant to grasp the complex concepts of programming.
If you really want to join such type of training institute then your step should be towards ADMEC Multimedia Institute in Delhi which provide training on both online and classroom modes with finest teaching meth ology. So, go ahead and join us.
