Syntax refers to the rules that govern how code must be written in a programming language. In C, this means following specific rules for writing statements and commands.
// Correct: Statements end with a semicolon printf("Hello World!"); // Incorrect: Missing semicolon printf("Hello World!")
Escape sequences are special characters used inside strings to represent characters that are difficult to type directly, like new lines or tabs.
// \n creates a new line in the output printf("Hello\nWorld!"); // Outputs: // Hello // World! // \t adds a tab space in the output printf("Hello\tWorld!"); // Outputs: // Hello World!
Comments are notes within your code that the compiler ignores. They are useful for explaining what the code does or leaving reminders.
// This is a single-line comment /* This is a block comment that spans multiple lines */
To run a C program, you need to compile it. gcc is a tool that converts your C code into a program that your computer can execute.
To compile a file named script.c, use: gcc script.c To compile and name the output program 'myProgram', use: gcc script.c -o myProgram
