 Given: The expression is floor (x*10+0.5)/10, where x is 3.5, 3.45, 3.76, 3.234, and 3.4567.
To find:Â The value of the expression, floor (x*10+0.5)/10, where x is 3.5, 3.45, 3.76, 3.234, and 3.4567.
Solution:
The output of the aforementioned statement, (x*10+0.5)/10, when:
x=3.5
The output of the aforementioned expression will evaluate to 3.500000. On substituting the value of x as 3.5, the expression will be evaluated. Then the function named ‘floor()’ is applied, which will return the largest double value which is smaller than or equal to integer x. The value it will return will be of type, double.
The following is the sample code:
The output of the above function will look like:
x=3.45
The output of the aforementioned expression will evaluate to 3.500000. On substituting the value of x as 3.45, the expression will be evaluated. Then the function named ‘floor()’ is applied, which will return the largest double value which is smaller than or equal to integer x. The value it will return will be of type, double.

- 4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward(Civil eng.)

Write a program to reverse the digits of a positive integer number. For example, if the number 8735 is entered, the number displayed should be 5378. (Hint: Use a do statement and continuously strip off and display the number’s units digit. If the variable numinitially contains the number entered, the units digit is obtained as (num % 10). After a units digit is displayed, dividing the number by 10 sets up the number for the next iteration. Therefore, (873510)is5and(8735/10)is873. The do statement should continue as long as the remaining number is not 0.) b. Run the program written in Exercise 3a and verify the program by using appropriate test data.arrow_forward
