Basic Commands of C Language

In C, there are several basic commands or language constructs that are used for programming. These commands perform various operations, control the flow of execution, and manipulate data. Here are some of the fundamental commands in C:

 

Comments:

 

// Single-line comment: Used to add comments on a single line.

/* Multi-line comment */: Used to add comments spanning multiple lines.

Variables and Data Types:

 

Declaration: Used to declare variables and specify their data types.

Assignment: Used to assign values to variables using the assignment operator (=).

Input and Output:

 

printf(): Used to print formatted output to the console.

scanf(): Used to read input from the user.

Control Structures:

 

if-else: Used to perform conditional execution based on a condition.

switch-case: Used to perform multi-way branching based on different cases.

for loop: Used for iterative execution of a block of code with a specified number of iterations.

while loop: Used for repetitive execution of a block of code as long as a condition is true.

do-while loop: Similar to a while loop but ensures that the block of code executes at least once.

Functions:

 

Function definition: Used to define functions that perform specific tasks.

Function call: Used to invoke a function and execute its code.

Arrays:

 

Declaration: Used to declare arrays to store a collection of elements.

Accessing elements: Used to access and modify individual elements within an array.

Pointers:

 

Declaration: Used to declare pointer variables that store memory addresses.

Dereferencing: Used to access the value stored at a memory address pointed to by a pointer.

Pointer arithmetic: Used to perform arithmetic operations on pointers.

Control Flow:

 

break: Used to exit from a loop or switch case statement.

continue: Used to skip the current iteration of a loop and continue to the next iteration.

These are some of the basic commands in C. By combining these commands, you can create more complex programs and perform a wide range of operations. It's important to understand these fundamental commands as they form the building blocks of C programming.
