Pulse Set

Working with Arrays, Strings, and Pointers in C++
After mastering basic constructs (variables, loops, functions), there is often a need to work with groups of data: store multiple values, process text, manage memory efficiently. These topics are a key step toward understanding how C++ enables more efficient code.
Pulse Set is a set of materials that helps systematically explore arrays, strings, and pointers. You will receive step-by-step explanations, code examples, self-study tasks, and typical usage scenarios.

What's inside Pulse Set:

• Module 1: One-dimensional arrays — declaration, initialization, index access, looping through arrays, finding sum/maximum/minimum.
• Module 2: Multi-dimensional arrays — two-dimensional arrays (matrices), initialization, nested loops for row/column processing, examples of matrix multiplication and transposition.
• Module 3: C-style strings (C-strings) — char arrays, null terminator, strlen, strcpy, strcat, strcmp functions, string input/output.
• Module 4: std::string — modern string class, creation, concatenation, character access, length(), substr(), find(), replace() methods.
• Module 5: Pointers — what a pointer is, & and * operators, pointer arithmetic, accessing array elements via pointer, passing arrays to functions.
• Module 6: Dynamic memory — new and delete, creating dynamically sized arrays, avoiding memory leaks, usage examples.

Who this material is for:
Suitable if:

• You can already write programs with loops, conditions, and functions
• You want to learn to work with large amounts of data at once
• You are interested in how C++ manages memory and why pointers matter

Not suitable if:

• You have not yet run programs with multiple functions and user input
• You are looking for classes, inheritance, or STL containers right away

What you will be able to master after completing it:
Create and process fixed- and variable-size arrays
Perform operations on matrices (two-dimensional arrays)
Use strings in classic and modern styles (C-strings and std::string)
Understand the concept of pointers and their connection to arrays
Allocate and deallocate memory dynamically
Pass arrays and strings to functions efficiently
Detect and fix common memory-related errors (out-of-bounds, dangling pointers)
