Question

write a pseudocode Write a complete program (including MAIN) that prompts/asks the user for a number between 0-255, reads in that number, and coverts it to a number between 0.0-1.0 (e.g. 0 becomes 0.0, 255 becomes 1.0, and 128 becomes 0.5). Note, this program is only a few lines long.

Answer 1

#include<iostream>
#include <iomanip>
using namespace std;

double convertValue(int num,int min,int max) {
   return ((double) (num - min)) / ((double) (max - min));
}
int main() {
   int num;
  
   while(true) {
       cout<<"Input an number in the range 0 to 255: ";
       cin>>num;
       if(num<0 || num>255) {
           cout<<"Incorrect. The number is out of range."<<endl;
       } else {
           break;
       }
   }
  
   cout<<"converted value is: "<< setprecision(2)<<(double)convertValue(num,0,255)<<endl;
   return 0;
}
