Making Function Calls
Based on what you've learned so far, you can write a C program that calls the integer_add() function to calculate an addition and then print out the result on the screen. An example of such a program is demonstrated in Listing 3.2.
Details of a C Function
Statements
In the C language, a statement is a complete instruction, ending with a semicolon. In many cases, you can turn an expression into a statement by simply adding a semicolon at the end of the expression.
For instance, the following
Expressions
An expression is a combination of constants, variables, and operators that are used to denote computations.
For instance, the following:
(2 + 3) * 10
Constants and Variables
Constant এর value কখনোই চেঞ্জ হয় না। অন্যদিকে variable কে ব্যবহার করা হয় ভিন্ন ভিন্ন ভ্যালু কে দেখানোর জন্য ।

CLASS 24: What You Can Do Now
You're now in the last chapter of this book. In this lesson you'll learn more about the C language from the following topics:
In Chapter 2, "Writing Your First C Program," you learned how to use the #include preprocessor directive to include C header files. Since then, the #include directive has been used in every program in this book.
In last hour's lesson you learned the basics of reading and writing disk data files. In this lesson you'll learn more about communication with disk data files. The main topics discussed in this hour are
Random access to files
Reading or writing binary data
In Chapter 5, "Reading from and Writing to Standard I/O," you learned how to read or write characters through standard input or output. In this lesson you'll learn to read data from or write data to disk files. The following topics are discussed in this lesson:
