Explore C++ data types, from fundamental and built-in types to modifiers, derived and user-defined types, with examples like int, float, double, char and the use of arrays.

Explore c++ data types and variables, learning how integers, real numbers, and strings store data in memory. See variable declaration, initialization, scope, and simple cout demonstrations in code examples.

Learn how C++ reference variables act as aliases for existing data, create a reference to a variable, and access or modify the value through both original name and its reference.

Explore C++ input and output streams with iostream and fstream, connect cout to the display and cin to the keyboard, and apply the insertion and extraction operators in simple examples.

Explore type casting in C++, highlighting implicit and explicit conventions and how automatic conversions can warn about data loss, with explicit casting granting control.

Declare constants in c++ with the const keyword to lock values after definition, explore integer and character constants, and observe output formatting with newline in basic examples.

Learn how constants and literals work in C++, define fixed values with the constant keyword, and use preprocessor directives to define pi and compute circle expressions.

Explore C++ operators, from arithmetic and modulus to increment and decrement, and learn prefix versus postfix usage, relational and logical operators, bitwise and comma operators with practical examples.

Discover the size of the comma operator and the conditional (ternary) operator in C++, including their syntax and sample code that shows how expressions evaluate to true or false.

Learn how to use C++ logical operators, specifically and, or, and not, in conditional statements, evaluate multiple conditions, and understand true and false outcomes with practical examples.

Explore the basics of control flow in C++, showing how control statements use boolean conditions to select code paths, including if statements, for loops, and while and do while loops.

Explore the if-else and nested if statements in C++, learning to test multiple conditions and execute corresponding code blocks for positive, negative, or zero inputs.

Learn how C++ statements drive flow control and decision making using if statements, else statements, and nested if statements, with boolean expressions and example code.

Learn to build a simple C++ program that checks whether a user-entered year is a leap year using nested if statements and divisibility rules for 4, 100, and 400.

Learn how C++ switch statements use case labels and an optional default, how break terminates a case, and how fall-through happens when breaks are absent.

Explore how the C++ goto statement performs an unconditional jump to a labeled block, transferring program control, with a simple even-odd example and a note that goto is discouraged.

Explore c++ loops and their types, including while loops, do while loops, and nested loops, and learn to execute code blocks multiple times while a condition remains true.

Master while loop, for loop, and do while loop in C++, repeating a code block until an end condition is met, with syntax and factorial examples.

Explain how the do-while loop in C++ executes the body at least once and checks the condition at the end, unlike for or while.

Explore the do-while loop in c++, a construct that executes at least once and checks the condition, with an example that prints numbers 1 through 8.

Explore how a while loop in C++ can become infinite when the condition never evaluates to false, using an example with i starting at 1 and increment and decrement operations.

Learn how to implement a for loop in C++ by initializing, testing, and updating the loop counter; apply it to compute factorials from user input.

Learn to use the for loop in C++ with initialization, a condition, and an increment to repeat code a set number of times. See an example printing 10 to 19.

Create a half pyramid triangle in C++ using a nested for loop, printing a row-by-row triangle based on the specified number of rows with cout.

Print a half pyramid of uppercase alphabets using nested for loops in C++ by taking a user input and printing from A up to the corresponding letter on each row.

Discover how to declare, define, and call C++ functions, use function headers and bodies, understand return types and parameters, and explore function pointers for dynamic behavior.

Learn to create and use user defined functions in C++, including prototypes and declarations, define a function outside main, and call it from main to perform tasks and return results.

Learn to use the cmath library in C++ to call built-in math functions, including calculating the square root with sqrt after including <cmath>.

Learn how to call functions by reference in C++, passing arguments by reference to modify actual variables and improve performance. See a swapping example that demonstrates reference parameters in action.

Learn how to declare and populate a 10-element integer array in C++, use for loops to input and print values, and understand 0-based indexing and contiguous memory.

Master declaring and initializing a two dimensional array in C++, with rows and columns, zero-based indexing, default zero values, and nested loops for student marks by subject.

Explore how pointers in C++ store memory addresses and enable dereferencing, including int*, char*, and pointer to pointer. See how to declare pointers and use the address operator.

Learn how to use null pointers in C++, assign a pointer to null at declaration when no valid address exists, and understand that null represents zero.

Understand how a void pointer in C++ can point to any data type, declare it, assign the address of a float, and print the pointer value.

Explore strings in c++, comparing c-type strings with std::string from the standard library, and learn to create, index, and print a complete string.

Explore printing the individual characters of a string in C++ by looping with an index and printing each character, contrasting with printing the whole string at once.

Learn how to take string input in C++ using getline and the extraction operator, compare cin with get line, and see how input streams read from keyboard into string variables.

Learn to read a multi word string in C++ using getline into a name and print it, then check its size or length.

Explore how dynamic memory allocation works in C++ by using the new operator, understanding stack and heap, and allocating memory for variables at run time.

Explore dynamic memory allocation with arrays in C++, using the new operator to allocate memory at runtime based on input and compute the sum of student marks.

Learn to obtain the current date and time in C++ using the C time library, with time(), ctime, and conversions to local time or UTC (GMT) via the ctime header.

Learn how to format and access date and time in C++ using the struct tm, time_t, and localtime to extract year, month, day, hour, minute, and second.
