Many later languages have borrowed syntax/features directly or indirectly from the C language. Like syntax of Java, PHP, JavaScript, and many other languages are mainly based on the C language. C++ is nearly a superset of C language (Only a few programs may compile in C, but not in C++). So, if a person learns C programming first, it will help him ...
C++ was created to add the OOPs concept into C language so they both have very similar syntax but both are a bit different from each other. Following are some main differences between C and C++ Programming language. 1. C++ supports OOPs paradigm while C only have procedural concept of programming. 2. C++ have exception handling capablities. In C, w...
Writing the First Program in C
The following code is one of the simplest C programs that will help us the basic syntax structure of a C program. Example: Let us analyze the structure of our program line by line.
Structure of the C program
After the above discussion, we can formally assess the structure of a C program. By structure, it is meant that any program can be written in this structure only. Writing a C program in any other structure will hence lead to a Compilation Error. The structure of a C program is as follows:
1. Header Files Inclusion – Line 1
The first and foremost component is the inclusion of the Header files in a C program. A header file is a file with extension .h which contains C function declarations and macro definitions to be shared between several source files. All lines that start with # are processed by a preprocessor which is a program invoked by the compiler. In the above example, the preprocessor copies the preprocessed code of stdio.h to our file. The .h files are called header files in C. Some of the C Header files...
2. Main Method Declaration – Line 2
The next part of a C program is to declare the main() function. It is the entry point of a C program and the execution typically begins with the first line of the main(). The empty brackets indicate that the main doesn’t take any parameter (See this for more details). The int that was written before the main indicates the return type of main(). The value returned by the main indicates the status of program termination. See this post for more details on the return type.
3. Body of Main Method – Line 3 to Line 6
The body of a function in the C program refers to statements that are a part of that function. It can be anything like manipulations, searching, sorting, printing, etc. A pair of curly brackets define the body of a function. All functions must start and end with curly brackets.
In order to execute the above program, we need to first compile it using a compiler and then we can run the generated executable. There are online IDEs available for free like GeeksforGeeksIDE, that can be used to start development in C without installing a compiler. 1. Windows:There are many free IDEs available for developing programs in C like Co...
