Question

Write a program that accepts input like the program in Display 7.8and that outputs a bar graph like the one in that display exceptthat your program will output the bars vertically rather thanhorizontally. A two-dimensional array may be useful.

//DISPLAY 7.8 Production Graph Program //Reads data and displays a bar graph showing productivity foreach plant. #include <iostream> #include <cmath> const int NUMBER_OF_PLANTS = 4;
void input_data(int a[], int last_plant_number); //Precondition: last_plant_number is the declared size of thearray a. //Postcondition: For plant_number = 1 throughlast_plant_number: //a[plant_number-1] equals the total production for plantnumber plant_number.
void scale(int a[], int size); //Precondition: a[0] through a[size-1] each has a nonnegativevalue. //Postcondition: a[i] has been changed to the number of 1000s(rounded to //an integer) that were originally in a[i], for all i suchthat 0 <= i <= size -1. void graph(const int asterisk_count[], intlast_plant_number); //Precondition: asterisk_count[0] throughasterisk_count[last_plant_number-1] //have nonnegative values. //Postcondition: A bar graph has been displayed saying thatplant //number N has produced asterisk_count[N-1] 1000s of units,for each N such that //1 <= N <= last_plant_number
void get_total(int& sum); //Reads nonnegative integers from the keyboard and //places their total in sum.
int round(double number); //Precondition: number >= 0. //Returns number rounded to the nearest integer.
void print_asterisks(int n); //Prints n asterisks to the screen.

   cout << "This program displays agraph showing "    << "production foreach plant in the company. ";

Explanation / Answer

please rate - thanks I had to change the variable name round to roundd--my compilercomplained about a conflict with the math library //DISPLAY 7.8 Production Graph Program //Reads data and displays a bar graph showing productivity for eachplant. #include #include #include const int NUMBER_OF_PLANTS = 4; void input_data(int a[], int last_plant_number); //Precondition: last_plant_number is the declared size of the arraya. //Postcondition: For plant_number = 1 throughlast_plant_number: //a[plant_number-1] equals the total production for plant numberplant_number. void scale(int a[], int size); //Precondition: a[0] through a[size-1] each has a nonnegativevalue. //Postcondition: a[i] has been changed to the number of 1000s(rounded to //an integer) that were originally in a[i], for all i such that 0
