- (True/False): A segment descriptor does not contain segment size informationarrow_forward(Display three patterns using loops) Use nested loops that display the following patterns in three separateprograms:arrow_forward(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward
- (TOPIC: Data Structures: Arrays, Strings and Structs) Write a program that will load 100 integers into array X. Separate the even from the oddvalued elements. The procedure should place the even values in ascending order startingfrom the first location of the original array and place the odd values in ascending orderstarting from the last position of the original array.

Create program using arrays to enter the following data: the names of typhoon Odette victims, their ages, and their current status (A – alive, D – died, I – injured, and M – missing). Your arrays should be proportional to the estimated population of the barangay. Enter the barangay's name and the estimated total population during the typhoon. Following data entry, display the following information according to their names – their name (in alphabetical order), their condition, and the number of people surviving, deceased, injured, and missing, as well as their percentage of the entire population.

Write a C code that prompts the user to input three integer values and find the greatest value of the three values. Page 3 Introduction to Computing By: Mr. Iyad Albayouk Example : Enter 3 integer vales separated by space: 10 15 20 The greatest value is: 20 2. Write a program that determines a student's grade. The program will read three scores and determine the grade based on the following rules: -if the average score >=90% and grade=A -if the average score >= 70% and grade=B -if the average score>=50% and grade=C -if the average scoregrade=F 3. Write C code to compute the real roots of the equation: ax+bx+c=0. The program will prompt the user to input the values of a, b, and c. It then computes the real roots of the equation based on the following rules : - if a and b are zero => no solution - if a is zero =>one root (-c/b ) - if b-4ac is negative =>no roots -…arrow_forward
- using c++ programming ::::: 16. (Pick 5 Lotto) Write a program to simulate a pick-5 lottery game. Your program should generate and store 5 distinct numbers between 1 and 9 (inclusive) into an array. The program prompts the user to enter five distinctbetween 1 and 9 and stores the number into another array. The programthen compares and determines whether the two arrays are identical. If thetwo arrays are identical, then the user wins the game; otherwise the program outputs the number of matching digits and their position in the array.Your program must contain a function that randomly generates thepick-5 lottery numbers. Also, in your program, include the functionsequential search to determine if a lottery number generated hasalready been generated.arrow_forward(the use of .length and the importance of string) *please explain the use of .length in this statement, and the importance of string in our overall code* if (studentNumber.length() > 10) //2019104921 I goto loop; else if(studentNumber.length() < 10) goto loop;arrow_forwardc) What is the output of the following piece of code in C?

(Algebra: solve 2 X 2 linear equations) You can use Cramer's rule to solve the following 2 X 2 system of linear equation: ax + by = e cx + dy = f ● x = ed - bf bc ad y = af - ec ad bc - Write a program that prompts the user to enter a, b, c, d, e, and f and display the result. If ad- bc is 0, report that The equation has no solution. Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0 Enter x is -2.0 and y is 3.0 Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0 Enter The equation has no solutionarrow_forwardUSE C++ (Display matrix of 0s and 1s) Write a function that displays an n-by-n matrix using the following header: void printMatrix(int n) Each element is 0 or 1, which is generated randomly.
