Description

C is a powerful system programming language and is commonly used to programme operating systems such as Unix. With this course, you will learn that one of the main advantages of programming in C is that it allows the programmer to write directly to memory. This means that key constructs such as pointers, constants, and strings can be used within the memory in an efficient and machine-independent fashion. You will also look into the functions of the char pointer.

You will then look into constants and string literals in C. You will learn that a string literal is a sequence of characters from the source character set enclosed in double quotation marks and are used to represent a sequence of characters which when taken together form a null-terminated string. You will also learn that you must always prefix wide-string literals with the letter L. You will also look into a new way to visualize RAM.

Upon the completion of this course, you will be able to confidently use pointers for direct memory access and manipulation in C as well as change the memory address contained within a pointer. You will also better understand why you need to learn about pointers and the char pointer. In addition, you will gain a better understanding of constants and string literals in C, the character string as an array of characters in C, and more!
