2025 C Programming Bootcamp - The Complete C Language Course

Master the while loop in C by exploring initialization, conditional expression, and update, and follow the entry-control flow illustrated with a print sequence from five to ten.

Showcase a while loop in C that prints numbers 1 to 10 using i, initialized to 1 with i <= 10 and i++, and explore formatting options.

Learn to sum digits of a number with a while loop by extracting digits via n mod 10 and updating a total; it also shows the product of digits.

Learn how the for loop, an entry control loop, initializes, checks a condition, executes a block, and updates, then repeats until false, demonstrated by printing 1 to 5.

Learn how to compute the factorial of a number in C using a for loop. Initialize fact to 1, loop i from 1 to n, and print the result.

Replace the for loop with a while loop to compute a factorial, initializing i to 1, multiplying fact by i, and incrementing until n.

Explore the do-while loop as an exit-controlled construct with initialization, a do block, an update, and a post-loop conditional check that repeats or exits, shown by printing 1 to 3.

Apply a do-while loop to compute the sum of numbers from 1 to n, prompting for n, updating i, and printing the final sum.

Explore how a loop and its conditional expression decide how many times the printf prints the sum, revealing the program's output is five.

Explore defining and using functions in C, including prototypes, calls, actual and formal parameters, headers, bodies, and return statements with a max value example.

Learn the four C function categories: arguments with return values, arguments with no return values, no arguments with return values, and no arguments with no return values.

Implement an iterative factorial function in C, called from main, using a for loop and returning the result for display, with examples like 5 factorial equals 120.

Implement a gcd function to find the greatest common divisor of two numbers by looping from 1 to the smaller value. Check divisibility, update the result, and return gcd.

Learn to compute the sum of digits of a number in C by writing a dedicated function, extracting digits with mod ten, updating a running total, and returning the result.

Learn call by value and call by reference, compare actual versus formal parameters, and see how pointers enable swapping within a function and reflect changes.

Demonstrates call by value and call by reference with an update function that passes x by value and y by address, illustrating how only y reflects changes via the pointer.

Explore where C variables are stored by memory or CPU registers, and learn the four storage classes—automatic, register, static, and external—along with their scope, lifetime, and default values.

Compare automatic and static storage classes with a practical increment example: automatic creates a new i initialized to ten on every call, while static preserves and increments i across calls.

Explore recursion by showing how a function calls itself, with a base case and a recursive call, using factorial to illustrate the step-by-step return from zero factorial to five factorial.

Implement factorial using recursion in C, with base case n equals zero returning one, and recursively computing n times fact(n-1). Read n with scanf and print the factorial result.

Compute the sum of numbers from one to N using recursion. Pass N to the function and use a base case at n = 1, summing n with the rest.

Explore how to compute the Fibonacci sequence using recursion in C, with base cases fib(1)=0 and fib(2)=1, and fib(n)=fib(n-1)+fib(n-2).

Explore one-dimensional arrays, their contiguous memory layout, and compile-time initialization, including examples with int x[5], indexing from zero, and printing array elements with a for loop.

Explore compile-time and runtime array initialization in C, learn to read and display elements with loops and printf, and compute the sum of array elements using user input.

Implement and use display, sum, and linear search functions to show array contents, compute the sum of elements, and locate an element with found/not found status and its position.

Find the frequency of a given element in a sorted array using a frequency function, and stop early with a break when a larger value is reached.

Sort an array in ascending order using a nested loop that compares elements and swaps with a temp variable, bringing the smaller element to the front and displaying results.

Master two-dimensional arrays in c by learning matrix syntax, row and column sizes, a[i][j] indexing, compile-time and runtime initialization, reading, displaying, and passing 2d arrays to functions.

Demonstrate transposing a matrix by interchanging rows and columns, and add two matrices A and B to produce and display the resulting matrix C.

Explore multi-dimensional arrays in C by building and traversing a three-dimensional array with two tables, three rows, and four columns. Learn syntax, initialization, reading, displaying, and passing to functions.

Explore how C strings are sequences of characters ending with a null terminator, and how to initialize, store, read, and display them using scanf, gets, and puts.

Show how to copy a string in C using strcpy and manually copy characters with a for loop, include printing s1 and s2, and the null terminator.

Learn to reverse a string in C using the built-in STR function from string.h, and flip a string without string.h by computing its length and printing from the end.

Learn string concatenation in c using string.h and strcat to merge string one with string two, and see how to create a space or concatenate without string.h by looping.

Learn how pointers store address of a variable and use indirection to access its value, while reducing code, enabling returning multiple values, and swapping numbers without a third variable.

Define a pointer to a pointer in C and its two-star syntax. Show accessing a variable's value with a single pointer and a double pointer using *p and **p.

Illustrates memory manipulation with a single pointer and a double pointer, updating x via *P and **P to yield 35.

Learn to implement call by reference in c by passing addresses to a function to sum two numbers and print the result using pointers.

Explore how a pointer to a function in C points to an addition function, calls it via the pointer, and returns the sum of two user-provided values.

Explore pointer increment and decrement in C by incrementing and decrementing pointers by one location, using size of integer for address arithmetic, and printing addresses to verify changes.

Demonstrates accessing a string with a pointer by treating the string as the base address, iterating a character pointer until the null terminator, and printing each character.

Learn to calculate a string’s length in C using a pointer, a while loop, and null terminator, then implement a separate function and return length via pointer arithmetic.

Learn to perform string concatenation in C using pointers by implementing a custom strcat-like function that moves to the end of str1 and appends str2 with a null terminator.

Learn to compare strings with pointers using a custom strcmp, returning the ASCII difference of the first non-matching characters and handling null termination with a while loop.

Explore how pointers access and traverse a one-dimensional array, using a base address, address of, and pointer arithmetic to read and display elements.

Learn to access and print elements of a two dimensional array in C using pointers, with pointer arithmetic and double dereferencing for a[i][j], including pointers to first and i-th rows.
