“As one variable goes up, the other variable goes down” is a description of:
Assume that name and age have been declared suitably for storing names (like "Abdullah", "Alexandra" and "Zoe") and ages respectively. Write some code that reads in a name and an age and then prints the message "The age of NAME is AGE." where NAME and AGE are replaced by the values read in for the variables name and age. For example, if your code read in "Rohit" and 70 then it would print out "The age of Rohit is 70.".
Complete the following program
When a machine reads blood pressure from a human body it displays two numbers they are called Systolicand Diastolic pressures.
The program will take systolic and diastolic reading as input from the user and displays a message whether the person's blood pressure is "Normal" or "Elevated" or "High
Blood Pressure".
Program consists of two functions as follows.
void input( .): This function is with two pass by reference parameters, and it reads input from the user.
string process..): It receives two numbers(systolic and diastolic) and then it determines and returns a category according to the table below.
Systolic
|80 to 120
| 120 to 139
High blood equal and
above 140
Diastolic

Write a program to calculate these quantities and also provide a cost estimate for the project. All your work will be done in the main function. First, you declare the variables needed for the calculation. After you write your class header, ask the customer to enter the patio’s width and length (in feet, a double or float). How many pavers will your customer need? First, calculate the patio area. There are many patterns for putting down pavers. Rather than lay out the exact pattern, allow 10% more square feet for pattern matching and waste. The pavers that you are selling today are 4 inches x 8 inches. Calculate the number of pavers needed and round up to the next whole paver.
