Some of the key attributes of c programming include.

  • Procedural programming – the procedural programming paradigm, which c conforms to, divides the program’s logic into functions or processes that carry out certain duties. Large programs may be managed and debugged more easily using this modular method.
  • Low-level manipulation – c is appropriate for system-level programming because it has capabilities that enable simple hardware and memory manipulation. This enables enormous control but necessitates careful memory management, which may be both a benefit and a difficulty.
  • Portability – c programs may be built and executed with just small alterations on several systems. This is due to the fact that c compilers produce machine-independent assembly code, enabling the development of programs that are compatible with a wide range of hardware and operating systems.
  • Efficiency – c is renowned for being efficient in terms of memory use and execution speed. It gives developers granular control over memory management and system resources, enabling them to performance-optimize their programs.
  • Standard library – the c language has a standard library that offers a variety of functions for carrying out everyday tasks like text manipulation, memory allocation, file operations, and more.
  • Syntax – c features a succinct, straightforward, and limited collection of keywords and constructions. It is an excellent language for learning programming ideas because of its simplicity.
  • Pointers – a key component of c, pointers enable direct memory access and manipulation. Despite being strong, if not handled wisely, they can potentially result in memory-related issues.
  • Data types – c offers a variety of basic data types (integers, floating-point numbers, characters, etc.), and it also allows users to construct their own data types using unions and structures.
  • Preprocessor directives – the preprocessor in the c language enables text replacement prior to compilation. This is frequently used for macro definitions, conditional compilation, and header file inclusion.

Basic for c programming/ basic c programming

To get you started, consider these basic ideas.

Welcome to the programme at mitacademy.

The first program people create in a new programming language is frequently the “welcome to mitacademys” program. “welcome to mitacademys” is printed to the console in plain text.

#include <stdio.h>

Int main() {

    printf(“welcome to mitacademys\n”);

    return 0;

}

Data types and variables.

The data types int (integer), float (floating-point number), char (character), etc. Are supported by c. These sorts of variables can be declared and used to hold data.

Int x = 1;

Float salary = 10000.45;

Char gender = ‘m’;

Input and output -you may input data using scanf and output it using printf.

Int x;

Printf(“enter x number value – “);

Scanf(“%d”, &x);

Arithmetic basics – addition, subtraction, multiplication, and division are supported in fundamental arithmetic operations in c.

Int sum = 1 + 2; // simple addition

Int minus = 15 – 7; // simple subtraction

Int mul = 2 * 4; // simple multiplication

Float division = 21.0 / 6; // simple division

Statements with conditions (if, else, if, else).

If statements can be used to form judgements depending on circumstances.

Int number = 1;

If (number > 1) {

    printf(“the number is greater than 1\n”);

} else if (number == 1) {

    printf(“the number is equal to 1\n”);

} else {

    printf(“the number is less than 1\n”);

}

(for, while, do-while) loops.

You can iterate across a piece of code using loops.

For (int x = 1; x <= 10; x++) {

    printf(“value of x %d\n”, x);

}

Int count = 1;

While (count < 10) {

    printf(“count %d\n”, count);

    count++;

}

Int num = 5;

Do {

    printf(“number is %d\n”, num);

    num–;

} while (num > 0);

These ideas offer a fundamental comprehension of c programming. You may investigate increasingly complex subjects as you proceed, including functions, arrays, pointers, linked list, and structures. From system programming to application development, c is a flexible language that can be utilized for a variety of tasks.

Structure in c programming/ c programming structure

A structure is a composite data type used in c programming that enables you to organize variables of various data types under a single name. It is simpler to manage relevant data when it is grouped together and distributed as a single object. With the help of structures, you may create your own unique data types, which can be very helpful for representing actual physical objects.

Here’s a guide on using and defining structures in c.

#include <stdio.h>

// define a structure

Struct course {

    char c_name[50];

    int c_id;

    float c_price;

};

Int main() {

    // declare a variable of the current structure type

    struct course course1;

    // modify the structure members

    strcpy(course1.name, “java”);

    course1.c_id = 101;

    course1.c_price = 1499;

    // actual display the information of active structure data

    printf(“course name – %s\n”, course1.c_name);

    printf(“course id – %d\n”, course1.id);

    printf(“course price – %.2f\n”, course1.c_price);

    return 0;

}

C programming factorial

Here is an example of a c program that calculates a number’s factorial using an iterative method.

#include <stdio.h>

Int main() {

    int x;

    int factorial = 1;

    printf(“enter any positive integer number – “);

    scanf(“%d”, &x);

    if (x < 0) {

        printf(“factorial is not support negative numbers -\n”);

    } else {

        for (int y = 1; y <= x; y++) {

            factorial *= y;

        }

        printf(“\n factorial of current number  %d is – %d.\n”, x, factorial);

    }

    return 0;

}

C programming example

The sum of two integers is calculated by the following straightforward c program.

#include <stdio.h>

Int main() {

    int l, k;

    printf(“enter the first l number – “);

    scanf(“%d”, &l);

    printf(“enter the second k number – “);

    scanf(“%d”, &k);

    int add = l + k;

    printf(“the addtion of %d and %d is = %d\n”, l, k, add);

    return 0;

}

C programming hello world/ small c program

Here is a c version of the famous “hello, world!” program.

#include <stdio.h>

Int main() {

    printf(“\n hello, world to c programming”);

    return 0;

}
