Introduction to Programming

• subject conditions
• recommended IDE (Visual Studio Code)
• template project in C++

Prerequisites

• variables, basic data types
• numeric, logic, and bitwise operators
• basic loops
• standard input/output with defined format
• functions

Topics and Tasks

• practice the above mentioned items
• read some numeric data from the standard input
• write a variable of unsigned int data type to the standard output in a binary form
• create a new method that will print a given number in its binary form
• ask the user for a number, read it and print it in the normal, binary and hexadecimal form

One-minute code

• Four easy examples that demonstrate how to repeatedly prompt the user to enter a number. Try to find the differences. -> DOWNLOAD

Prerequisites

• functions/methods ... basic notations, return values, etc.
• random numbers
• arrays

Topics and Tasks

• make a static declaration of an array of ten elements and initialize such array to following values {5, 7, 8, 6, 20, 100, 15, 13, 4, 5}
• create a function that fills a given array with random numbers from interval <0,1>
• create a function that returns the largest number in a given array and index of this number
• create an array of 1M elements
• create a matrix M[m x n]. Fill the matrix with integer numbers such that the M[i, j] = i + j, where i∈<0, m-1>, j∈<0,n-1>, m=100, and n=100.
• create a matrix M[1000x1000]. Fill the matrix with random numbers from interval <0,255>. This matrix represents a grayscale image. Create a histogram for this image.

Prerequisites

• functions
• standard math library

Topics and Tasks

• a short recap of the previous tasks
• write a function f(x) that returns a single value for every x from the interval <-1000,1000>, if (x mod 3 == 0). The function is given by the following formula:

• think about the optimization. Do you really need the division and modulo? What about the absolute value?
• try to modify the function such that the user can set the interval (upper and lower bound).
