Each function should accept two integer parameters indicating the minimum and maximum X value to be plotted. The functions should have no return values. Create class-level constants for things we might wish to change later, e.g., a char called PLOT_CHAR that holds an “x” (per samples below), another char called FILL_CHAR that holds an unobtrusive character like ASCII 183, generated with a cast, e.g., (char)183.

Use C++: Develop a Tic Tac Toe game that will match a player against the computer. Do’s: Use a typical 3 x 3 board. The horizontal axis should be labeled A, B, C. The vertical axis should be labeled 1, 2, 3. For Example the picture attatched. Use User-Defined Functions. Use Branching. Use Loops. Use String functions. Randomly determine who will move first, the human or computer. Assign O to the computer and X to the Human player. Ask the user to select their move using the horizontal and vertical position. For example: A1 for the upper left square, or B2 for the center square. After each move, redraw the board with the X’s and O’s in the right positions. After each game, ask the user if they want to play again. If they do, start the game again. Bullets 8 and 10 are very important. Do not’s: Don’t use User Classes or Objects Don’t use images Program must use: functions loops branching string functions

Python Programming Problem: The first line consist a number X i.e., the number of test cases. The first line consists three space-separated integers N, Q1, and Q1. Then Q1 lines follow, each containing a description of a road proposed0. Each of these lines contains three space-separated integers p, q, and r, where p and q denote the end points of the road and r denotes the associated cost. Then Q1 lines follow, each containing a description of a road proposed by Brian's company in the same format. Output a single line for each test case. If it is impossible to choose a subset of the roads in such a way that for each pair of cities, there is exactly one path of roads connecting them, output a single line containing "No way" for that test case. Otherwise, output a single line containing two space-separated integers: the maximum profit Brian can gain and the minimum total cost of the chosen roads that yields the maximum profit. Input: 1 3 1 1 0 1 1 0 1 3 Output: No way
Write a complete C program that analyse the statistics of 5 YouTubers’ debut video. The program should: (i) Prompt the user to key in the number of views of 5 YouTubers’ debut video. (ii) Identify which YouTuber has the minimum view - Apply non-return value function, include parameter list if necessary (iii) Identify which YouTuber has the maximum view - Apply non-return value function, include parameter list if necessary (iv) Calculate the average views - Apply return value function, include parameter list if necessary (v) Determine whether the YouTuber is popular or not by comparing to the average views. If the YouTuber’s debut video views are greater or equal to the average views, then the YouTuber is popular, else, not popular. Requirements: - Apply array - Apply string.h library SAMPLE OUTPUT: Enter no. of views for - YouTuber 1: 987 YouTuber 2: 1010 YouTuber 3: 3217 YouTuber 4: 4532 YouTuber 5: 899 Minimum: YouTuber 5 [899 views] Maximum: YouTuber 4…
I need help to write a c program code for the following questions Determine the following averages of the percentage of the population that are diagnosed with diabetes. Present your outputs clearly within your program with labels (explanatory text), not just the numbers by themselves. 1) Provincial averages (Ontario, Quebec, British Columbia, Alberta). One average per province (for all years and age groups). 2) One national (Canada excluding territories) average for all years and age groups. 3) Yearly averages (2015, 2016, 2017, 2018, 2019, 2020, 2021). One average per year (all age groups together) for each province and the whole country (Canada excluding territories) for a total of 35 averages. 4) The average percentage of diabetes among age groups (35-49, 60-64, 65+). One average per age group (all years) for each province and the whole country (Canada excluding territories) .
