Explore widening conversions in C++, from bool and char to int and float, noting information loss when converting float to int and nonzero to bool. Compare static_cast with c-style casts.

Learn to print in c++ with cout using the insertion operator for literals, variables, expressions, and booleans (default 1/0); compare endl versus \n and operator overloading for custom types.

Explore fixed and scientific formats for floating-point numbers, focusing on precision and trailing zeros. See how e notation and currency-like precision apply to X and Y.

Explore arithmetic operators in C++ including binary plus, minus, multiply, divide, and percent operator for integers and floating point values, understanding unary increments and decrements with postfix versus prefix behavior.

Explore left and right shift operators in C++, left shift multiplies by 2^y. Invert unsigned bits with not, and signed behavior depends on two's complement.

Learn to find the last digit of a number using modulus 10. Handle negative inputs by applying the absolute value to obtain the positive last digit.

Explore how to find the nth term of a geometric progression using the first term and common ratio, with the formula an = a r^(n-1) and example code.

Learn an else if ladder in C++ that reads a user number and prints positive, negative, or zero, illustrating conditional flow in beginner to advanced programming.

Explore the switch statement in c++ for multi-way branching with an integral move. Update x and y for left, right, up, and down, with break and default notes.

Learn how functions in C++ encapsulate reusable code, allowing you to define, call from main, and return values, with parameters and return types demonstrated by getMax and greeting.

learn prime factorization by expressing numbers as products of prime numbers, with examples like 50 = 2*5*5 and 20 = 2*2*5, and test divisibility from 2 to n.

Explore the while loop in C++, its condition, and how to form a code block with curly braces. See how counters, true conditions, and semicolon mistakes trigger infinite loops.

Explore nested loops by building multiplication tables with an outer loop from 1 to n and an inner loop printing multiples from 1 to 10, applying to grids and matrices.

Explore C++ patterns by using loops to print star and number patterns, including horizontal, vertical, and 5x5 grids, with nested loops and endl.

Learn to generate a triangular star pattern in c++ using nested loops; given n, print i stars on the i-th row to form a right triangle.

Count digits in a number by dividing by 10 in a loop and tallying until the value is zero. See 1234 as four digits and 24 as two digits.

Declare and initialize arrays in C++ by data type, name, and square brackets, use initializer lists, and note contiguous memory, size inference when omitted, and zero initialization.

Learn to count distinct elements in an array using a simple nested-loop approach that checks prior values and increments the count for first-time elements, illustrated with 10, 20, and 30.

Compute the average of numbers in an array by summing elements and dividing by the count, as shown with 10, 20, 30, 40, and cast to floating-point.

Explore the address and dereference operators in C++, learn how & yields a variable's address and * retrieves the value at that address, and distinguish between references and pointers.

Array parameters are received as pointers in C++, so size calculations inside a function are unreliable; avoid computing array size there and pass the size as a separate parameter.

Learn how null pointers prevent wild pointer errors by initializing pointers to null, checking before dereferencing, and using null to signal invalid results in functions and data structures.

Master pointer arithmetic in C++, using increment, decrement, and pointer addition or subtraction to move through arrays and measure element distances. See how pointer type sets movement.

Practice questions on pointers, exploring sizeof results for arrays and pointers, pointer arithmetic, dereference operations, and pre/post increment behavior.
