Projects in C

Tic Tac Toe Game Development using C: While making a Tic Tac Toe game using C language, it is important to make use of arrays. The Xs and Os are kept in different arrays, and they are passed between several functions in the code to keep track of how the game goes. With the code here you can play the game choosing either X or O against the computer. This Tic Tac Toe C game is such that you will have to input a numerical character, from 1 to 9, to select a position for X or O into the space you want. For example: if you are playing with O and you input 2, the O will go to first row – second column. If you want to place O in third row – first column, you have to enter 7. And, it is similar for the other positions. This has been done this way because it is just a console application without graphics designed in C language. The gotoxy function has been used to print text in any part of the screen. Did you know? In Tic Tac Toe game, there are 765 states of space complexities

Getting started with C !!

Before, we get started with C programming and installation guide we first need to understand the basic terminology associated with it. To help us build the logic and frame sentences (basically syntactical sentences understandable by compiler). Why C Programming? the most obvious question in the mind of a budding programming is why to learn this language, because: it has modularity it is compiler based it is used in platform development it is structure oriented it is a middle level language uses of pointers uses recursions it is simple to understand over other languages it is light but powerful enough to create some light projects to a malware it is fast and efficient in nature it has portability # this symbol is called as preprocessor . As the name says it, it pre-processes some work before executing the whole program. This symbol is used with include this term is used to include a specific file basically header files having .h extension which are in your C bin folder these speci

Memory Operations in C

C Dynamic Memory Allocation: Sometimes the size of an array which we declared may be insufficient in storage. To resolve this issue, we can allocate memories manually during run-time. This process is known as dynamic memory allocation in C programming. To allocate the memory dynamically in C, library functions used are malloc() , calloc() , realloc() and free() are used. These functions are defined in the <stdlib.h> header file. C malloc() The name "malloc" stands for memory allocation. The malloc() function reserves a block of memory of the specified number of bytes. And, it returns a pointer of void which can be casted into pointers of any form. Syntax: ptr = (castType*) malloc (size); C free() Dynamically allocated memory created with either calloc() or malloc() doesn't get freed on their own. You must explicitly use free() to release the space. Syntax: free (ptr); C calloc() The name "calloc" stands for contiguous allocatio

Questions On Conditional Constructs

"Understand the flow of the program and try practicing it on your own and let me know in the comments section were you able to do it in the very first place on the basis of your understanding or how do you find these questions, Goodluck :) " Question 1: Even or Odd If else Question 2: Calculator Switch case Question 3: Prime Number in a range If else (flag and break concept) Code: Output: Question 4: Day in a Week by number Switch case Question 5: Palindrome if else and while loop (though we will discuss this in later section but you can see here how it works) Question 6: Program to find the maximum number of placements in a Branch using if else Output: Question 7: Season using if Else and or operator Question 8: Fuel Consumption Calculator using If else Output: Question 9: Leap Year using if else Question 10: Greater among Three numbers using if else These 10 questions are a mix of different difficulty level hope this will help you in br

Using for Loop and Questions

The for Loop Construct: The for loop construct is far superior and more powerful than the loop constructs provided by the language. The construct provides a compact way of specifying the statements the statements that control repetition of the steps within the loop. Syntax: for(starting_value ; ending range ; increment/decrement) Example 1: Leap year within range Example 2: Table for 2 Example 3: Table from 2 to 20 Example 4:prime number user defined Example 5: factorial Example 6: pattern left side star * * * * * * * * * * * * * * * Example 7: inverted pattern left side star * * * * * * * * * * * * * * * Example 8: star pyramid * * * * * * * * * * * * * * * * * * * * * * * * * Example 9: inverted pyramid * * * * * * * * * * * * * * * * * * * * * * * * * Example 10: hollow diamond star pattern ********** **** **** *** *** ** ** * * * * ** ** *** *** **** **** ********** C

Pointers in C

Pointers in C: This is available only in C language. Pointer points to the address of any variable, dynamic in nature and used in memory allocation purpose. Also, it is better to assign null value to a ptr as their is garbage value. Syntax: type *var_name; Example 1: //program to show pointer in C #include<stdio.h> int main ( ) { int var = 20; int *ip; ip = &var; printf ("address: %x\n",&var); printf ("address stored in ip variable: %d \n",*ip); return 0; } Example 2:

Installation guide for C

This is a installation procedure for C. I would recommend you, using Dev C++ or code blocks for C compiler as I personally like the interfaces of both these two but I use Dev C++ as it has themes and dark mode (enables less strain on eyes when you are working for hours). Here, I am attaching the links for the installation guides of both these softwares and link to their executable files from where you can find the downloading page: >>Dev C++ : video: click here executable: click here >>Code blocks: video: click here executable: click here For those who wish to use a online editor and save their time or doesn't have enough storage can also opt for online compilers such as GDB compiler for C it is the best one also Jdoodle these sites feature many compilers apart just from C and there are many more but these two will get your work done. >>GDB: page: click here >>Jdoodle: page: click here Book "Let us C" - Yashwant Kanetkar clic

Some Extra problems and resources on C

Some Extra problems and questions on C : Congratulations !!! dear learner if you have reached here, here are some more resources for you to solve problems based on C and some advance problems as well. Here, I'm attaching my github repo link kindly use it and learn from it. Github: https://github.com/ssg8288/C-Programs-Additional-Content Enjoy and happy coding :)

Recursion in C

Recursion in C: It is a function in C language that calls itself within its boundary. Also, a caution note while programming it has to be kept in mind about the exit function else the program will go on infinite number of times. Example :The following program calculates the factorial of a number using a recursion Example :The following program generates the Fibonacci series for a number using a recursion

Using Constructs- III

Loop Constructs While Loop A While loop block of statements the condition is evaluated first and if it is True the loop body is executed. After execution of the loop body the condition in the while statement is evaluated again.This repeats until the condition becomes False. Syntax: while (argument) { // statements inside the body of the loop } Do...while Loop The do...while loop construct like the while loop construct is used in situations where operations is to be performed is not known, and is dependent on a condition, which changes within the loop body. Also, iterations are to be performed until the specified loop condition becomes False. Syntax: do { // statements inside the body of the loop } while (arguments); It differs from the while loop always remember !!! Example 1: Accept any number and print total number of digits Using While loop Example 2: Print number series Using While loop Example 3: Reverse of a number Using While loop Example 4: Program t
