Programmers 8 in 1 Bundle

Explore decision making in C using the ternary operator, if-else chains, and switch statements; learn relational, equality, and logical operators, and understand assignment vs. comparison and operator precedence.

Explore arrays that store values of the same type, indexed from zero, using a five-element grades array to compute and print an average with float division and two-digit formatting.

Explore pointer basics with int and char pointers, learn about addresses and the size of pointers, and see how argc and argv form an array of strings in a demo.

Explore pass by value versus pass by reference, showing how values swap inside a function but require pointers to affect outside state, and how arrays behave as pointers.

Learn to build a program that reads two numbers with formatted input via scanf, adds and multiplies them, and references the GCC function list to locate input functions like stdio.h.

Learn to use scanf for input by prompting for two integers, then compute and print their sum, product, and the maximum, with functions for input and arithmetic.

Find max and min in an array using pointer arithmetic in C, demonstrating equality with array indexing, the role of limits.h, and pointer safety concerns.

Learn how structures form composite types with dot and arrow access, using struct and typedef. Grasp stack and heap memory, and dynamic allocation with malloc and free for structures.

Demonstrates allocating a book structure on the heap with malloc, accessing fields via dot and arrow operators, and freeing memory to prevent leaks, while contrasting heap and stack storage.

Explore how linked lists use pointers to connect elements, implement singly and doubly variants, and support add, delete, and memory management, with stacks and queues as typical uses.

Demonstrates a stack built as a singly linked list with push and pop operations on integer data. Includes add, subtract, multiply, divide, swap, clear, and print.

Explore a simple stack-based command interpreter that parses command line arguments to push integers or floats, swap elements, and manage a memory slot.

Capture an entire input line in C++ by using getline with a maximum length (for example 256) instead of cin, enabling names like John Doe to print fully.

Explore how string streams turn strings into streams and back, using istringstream and ostringstream to handle input and output in C++, and how this improves type checking and safety.

Open an input file stream and an output file stream, read lines with getline into a string, write them to the output, and close both streams.

Learn how to declare a class in C++ using the class keyword, define a point with private x and y, and declare constructors and getters.

Learn how destructors manage memory in C++ by seeing why deleting a line doesn't automatically delete its heap-allocated points, and how to implement a destructor to prevent memory leaks.

Explore the essentials of a Java program by creating a main class, understanding packages, and using System.out.println and exit codes to run and debug.
