C Syntax
Comments:- A C program is made up of one or more statements, each of which performs a specific task. Comments can be simple, such as assigning a value to a variable, or more complex, such as invoking a function.
Variables:- C programs use variables to store data. Variables are reported by data type and name, and can be assigned a value. C supports many data types, including integers, floating-point numbers, characters, and pointers.
Functions:- C programs are typically organized around functions, which are pieces of code that perform a specific task. Functions can take arguments, which are values passed to the function for processing, and can return a value.
Control structures:- C provides different control structures for branching and looping. These include if-else statements, switch statements, while and do-while loops, and for loops.
Operators:- C provides a professional operator to perform arithmetic, logic, and bitwise operations. These include arithmetic operators (+, -, *, /), comparison operators (>, <, >=, <=, ==, !=), logic operators (&&, ||, !), and bitwise operators (2). & . , |, ^, ~ ).
Preprocessor instructions:- C programs can include preprocessor instructions, which are instructions that are processed before the code is compiled. These include comments, which allow external files to be added to the program, and macro definitions, which allow code to be replaced by other code at compile time
The C syntax is designed to be simple, flexible, and efficient. Following the following.
Syntax
You have already seen the following code a couple of times in the first chapters. Let’s break it down to understand it better:
Example
int main() {
printf(“Hello World!”);
return 0;
}
Example explained
Line 1: #include <stdio.h> is a header file library that lets us work with input and output functions, such as printf() (used in line 4). Header files add functionality to C programs.
Don’t worry if you don’t understand how #include <stdio.h> works. Just think of it as something that (almost) always appears in your program.
Line 2: A blank line. C ignores white space. But we use it to make the code more readable.
Line 3: Another thing that always appear in a C program, is main(). This is called a function. Any code inside its curly brackets {} will be executed.
Line 4: printf() is a function used to output/print text to the screen. In our example it will output “Hello World!”.
Note that: Every C statement ends with a semicolon ;
Note: The body of int main() could also been written as:int main(){printf("Hello World!");return 0;}
Remember: The compiler ignores white spaces. However, multiple lines makes the code more readable.
Line 5: return 0 ends the main() function.
Line 6: Do not forget to add the closing curly bracket } to actually end the main function.
