Answer:
Here is the Python and C++ program.
Python program:
gallons_paint=0.0 #declare and initialize gallons_paint
wall_area = float(input()) #prompts user to enter wall area
gallons_paint = wall_area / 350 #formula to compute gallons of paint needed to cover the given square feet of walls
print(gallons_paint) #display the result
C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects like cin cout
int main(){ //start of main() function body
float wall_area,gallons_paint=0; //declare variables
cin>>wall_area; //reads input wall area from user
gallons_paint=wall_area/350; //formula to compute gallons of paint needed to cover the given square feet of walls
cout<<gallons_paint;} //print the result
Explanation:
The program prompts the user to enter the area of wall and stores the input value in wall_area
Suppose the user enters 250 as wall area
The the formula gallons_paint=wall_area/350; works as follows:
gallons_paint = wall_area/350;
= 250/350
= 0.71428
gallons_paint = 0.71428
So the output is:
0.71428
The screenshot of the program along with its output is attached.
