Chapter 2.4, Problem 25STE
Consider a quadratic expression, say
x2 – x – 2
Describing where this quadratic is positive (that is, greater than 0), involves describing a set of numbers that are either less than the smaller root (which is –1) or greater than the larger root (which is +2). Write a C++ Boolean expression that is true when this formula has positive values.

Write a complete C++ program that prints the change in population of the the United States:
p = p + Bp
Dp
where p is the population, B is the birth rate of 12.4 births for every 1000 people (12.4/1000) each year, and D is the death rate of 8.4 for every 1000 people (8.4/1000). In 2017, the
population of United States was 325.7 million. Your program should ask the user for the number of years and print expected population over those years starting from 2017. Each line
should have: the year and the population (in millions).

When a customer wants to buy a ticket, the clerk at the ticket window asks the visitor if he or she needs a rest area, and if so, which one: left, right, or both. We know that in the audience they are expected to appear, their L needs a left-handed position, their R needs a right one, Z does not need a single one and B needs both. Your job is to count the number of people who can attend the show. In the theatre there are N rows with each M seat. There is only one lounge between the two adjacent seats.

- Write a C program that reads an integer from the user (keyboard), namely n. Your program should print all positive numbers that are smaller than n and satisfy the following condition: If we denote the number with a and sum of its digits b then a+b is a perfect square. You should print the numbers in ascending order and print their digits separated by “-“ symbol from the least significant to the most significant on the same line as the number. At the end of each line you should also print a+b. Example: If the user enters n : 150, then the output should be as follows: 2 2 4 8 8 16 17 7-1 25 27 7-2 36 38 8-3 49 72 2-7 81 86 6-8 100 135 5-3-1 144arrow_forwardwrite this program in c++arrow_forwardC Programming "Functions"arrow_forward
- A program in the C language that receives from the user an actual number up to 3 digits after the dot, It can be assumed that the number does not contain more than 3 digits after the dot. The program will separate it into a whole and an actual part. The number should be printed as an integer followed by a fraction, Pay attention to the accuracy of the actual numbers to handle a situation where there is an inaccuracy (like 2.3 Which appears as 2.299). Note: The MODF function must not be used, The things that are only allowed to be used are Types, operators and conditions, For example: The number 3.532 will be printed: 3 532/ 1000 The number 43.75 will be printed: 43 75/ 100 The number 84.5 will be printed: 84 5/ 10 The number 2.3 will be printed: 2 3/ 10 The number 85 will be printed: 85 0/ 10 The number 33 will be printed: 33 0/ 10arrow_forwardUsing C language. Write a program that reads two matrices of integers. It then generates the sum, difference and product of the two matrices. The sum of the two matrices of the same size is a matrix with elements that are the sums of the corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes. If A and B are matrices of the same size, then we define subtraction as follows: A - B = A + (-B). Thus, to subtract matrix B from matrix A, we simply subtract corresponding elements. To multiply a matrix by another matrix we need to do the "dot product" of rows and columns. The "Dot Product" is where we multiply matching members, then sum up: (1, 2, 3) • (7, 9, 11) = 1×7 + 2x9 + 3x11 = 58 We match the 1st members (1 and 7), multiply them, likewise for the 2nd members (2 and 9) and the 3rd members (3 and 11), and finally sum them up.arrow_forwardwrite a program c ++ You are making a program for a bus service. A bus can transport 50 passengers at once. Given the number of passengers waiting in the bus station as input, you need to calculate and output how many empty seats the last bus will have.Sample Input: 126Sample Output: 24Explanation: The first bus will transport 50 passengers, leaving 126-50=76 in the station. The next one will leave 26 in the station, thus, the last bus will take all of the 26 passengers, having 50-26=24 seats left empty.arrow_forward
