(IN C LANGUAGE) Cumulative Addition: Computer selects a number between 7 and 23 at random. User will only add 2, 3 or 5 numbers to reach that number.For example: To reach 14: User will enter 5 5 2 2 (4 input).Also he can enter 2 2 2 2 2 2 2 (7 input) or 3 3 3 3 2 (5 input). https://www.bartleby.com/questions-and-answers/in-c-language-cumulative-addition-computer-selects-a-number-between-7-and-23-at-random.-user-will-on/0509c740-d993-44ed-a468-7e02da552600
PROBLEM: Write a program that prompts the user to input three positive angle values in degrees to determine which type of triangle it is (acute, right, obtuse). SPECIFICATIONS: - You may only use the codes that we studied under our lectures - All lines of codes should have a comment. - Save your cpp file as Surname - PE (Example: Pangaliman - PE.cpp) TEST CASES: If a user inputs three valid angle values: Enter the first angle in degrees: 60 Enter the second angle in degrees: 30 Enter the third angle in degrees: 90 Result: You have a right trianglel If a user inputs any negative angle values: Enter the first angle in degrees: 45
(Sort three integers) Write a program that prompts the user to enter THREE integers and display the integers in decreasing order. Prepare your problem analysis and algorithm (pseudocode or flowchart) to plan your solution.
Find the error in each of the following. (Note: There may be more than one error.)a) For (x = 100, x >= 1, ++x) {printf("%d\n", x);}b) The following code should print whether a given integer is odd or even:switch (value % 2) {case 0:puts("Even integer");case 1:puts("Odd integer");}
QI: tinclude (a) Write two different techniques to declare and initialize a variable with an example. using namespace std; void repchar(char, int); int main() (b) Write a program that simulates a simple cakulator. It reads two integers and a character. If the character is a +', the sum is printed; if it is a , the difference is printed: if it is a *", the product is printed; if it is a ", the quotient is printed; and if it is a %', the repchar(", 43): cout "Data type Range" endl; repchart-, 23). cout e "char-128 to 127" < endl
3. Write Python expressions or assignments as specified:a. Assign x to be 5, y to be 10, and z to be 8.b. Write an expression that evaluates to the average of x, y and z.c. Write an expression that evaluates to the largest value among x, y, and z.d. Write an expression that evaluates to the median value among x, y, and z (Hint:the median of a, b, and c is a+b+c - max{a,b,c} - min{a,b,c}.)
5) Analyze the following code: boolean even = ((240 % 2) = 0): if (even) System.out.println("It is even!"): a. The program has a syntax error b. The program has a runtime error c. The program displays “It is odd!" d. d. The program displays "It is even!" else Page 2 of 6 System.out.println("It is odd!");
What is the difference between the statements continue and break?
(Slope of a line) Write a program that prompts the user to enter the coordinates of two points (x1, y1) and (x2, y2), and displays the slope of the line that connects the two points. The formula of the slope is (y2 - y1)/(x2 - x1).
(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1+2+3+4 = 10 and 1 +0 = 1, while 1235 is not (1 +2+ 3 +5 = 11 and 1 +1 = 2). Write a program that prints out the first N magic numbers, seven on each line. Here is the sample output: Enter a positive integer number: 30 1 10 19 28 37 46 55 64 73 82 91 100 109 118 127 136 145 154 163 172 181 190 199 208 217 226 235 244 253 262 You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of value Step 2: Repeat Step 1 until we get a single digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise not
