Learn how to determine an array’s size in C++ using the built-in size of operator, with a practical example of six elements and the memory bytes involved.

Learn to implement selection sort on a C++ array, determine its size, swap elements, and print the array before and after sorting for clear, hands-on practice.

Explore multi-dimensional arrays in C++ by building a 2x4 array of letters, learn to access elements with row and column indices, and read or modify values using zero-based positioning.

Learn c++ pointers, creating pointers, and memory address allocation, with delegation passing parameters. Explore arithmetic, composition, dynamic memory allocation, and resizing smart, unique, and shared pointers, with real-world examples.

Learn what a pointer is in C++, a variable that stores a memory address to another variable, enabling pass by address and dynamic memory usage, with declarations using a star.

Illustrates creating reference variables with the ampersand operator and using them to alias an existing variable in C++.

Learn how to obtain a variable’s memory address in C++ using the ampersand operator, and understand how references and pointers enable memory management and improve app performance.

Explore constant pointers in C++ by using the const keyword to fix a pointer's address while allowing modification of the value it points to, with examples of constants and errors.

Explore pointer arithmetic in C++ by using pre- and post-increment and post-decrement to navigate an array, print addresses, and access values through a pointer.

Learn to compare a pointer with array elements using the full set of comparison operators, and understand pointer arithmetic with a while loop to access and print element values.

Resize a pointer dynamically to store a user-defined number of student GPAs or scores using new, then display data and free memory with delete[].

Explore how smart pointers manage memory by automatically releasing unused resources, avoiding manual delete, with explicit constructor, destructor, and operator overloading in modern c++.

Explore unique pointers in C++, learn how a unique_ptr manages a single object, transfers ownership via move, and use it with a rectangle class to compute area.

Explore c++ strings: create, modify, count characters, find substrings, perform string to numeric conversions, handle escape sequences, formatting, and raw strings with input and real-world examples.

Learn to work with strings in c++, creating and managing multiple strings using the string library. Build dynamic employee data output with input, concatenation, and formatted cout printing.

Learn how to locate a substring within a string using the find method in C++, returning the index position when the target word is found.

Learn how to extract a portion of a string in C++ using the substring method, using the position and length parameters to crop output such as zero-based segments.

Learn to read independent characters from a string in C++ by two methods: using str.at(i) and the array subscript operator str[i], looping from 0 to str.length() and printing with cout.

Discover how to convert strings to numeric values in C++ using string stream. Learn declaring string and int variables, building a string stream object, and extracting integers for arithmetic operations.

Master escape sequences in C++ strings, including newline, tab, backspace, backslash, and the null character, to format output precisely. See how these sequences affect string literals and program results.

Learn how to represent and print C++ strings without escape sequences by using raw strings, including the R\"(... )\" syntax, to print multi-line and special characters exactly as written.

Learn to declare and use structures in c++, grouping related variables into a struct with members of different data types, and initializing and accessing them.

Learn to access and initialize a C++ struct using the dot operator, set members like my number and my string, and display results with cout.

Create a rectangle structure with a default constructor and a method to compute its area, then instantiate objects and access the area via the dot operator.

Compare structures and classes in C++, highlighting default public vs private members, constructors and destructors, stack versus heap allocation, value versus reference types, and syntactic similarities.

Learn C++ structures with methods, implement default constructors, and compute the area of a rectangle via dot notation; practice with multiple methods.

Explore structures and functions by passing a structure as a function argument, using prototypes and main to define, declare, and implement a person structure with name and salary.

Learn to define structures, pass them to functions, and implement prototypes in C++ with a person example, including input, output, and member access.

Explore file streams in C++ by using the standard library to read from and write to files with cin, cout, ifstream, and ofstream, including text, binary, and CSV formats.

Learn how to read text from files in C++ using file streams and string streams, with getline, open checks, looping, and proper closing.

Learn how to create and write to a text file in C++ using file streams, including opening the file, writing content such as shopping cart items, and closing the stream.

Explore string streams in c++, reading from a string as a stream to parse input with operator<< and operator>>, and count words in the given string.

Convert integers to strings in a C++ program using a string stream. Insert user input into the stream and produce the converted string for display.

Learn how to write a binary file in C++ using ofstream, writing a student structure with a roll number and name to a binary file, with basic error handling.
