Question

Using C++, create a program that will input the 3 game scores of a player and then output the level of the player with a message.
 
Specifications
Prompt the user to input 3 game scores (double values).
Compute the weighted average (DO NOT JUST ADD AND DIVIDE BY 3!) score as follows:
20% for first game, 30% for second game, 50% for last game
Earlier games are worth less in the weighted average; later games are worth more.
Print the level of the player expertise based on the weighted average as follows:
average >= 2000:  expert
average is >= 1800 but is < 2000 master
average is >= 1500 but is < 1800: advanced
average is >=1000 but is < 1500: intermediate
average < 1000: beginner
For each expert player print: "Congratulations! You are an expert! "
For each player that is master or advanced print: "Good Job!"
For each player that is a beginner: "Keep on practicing!"
Run the program 2 times on the following input:
Run 1:
600 1500 900
Run 2:
1800 1500 2000

Answer 1

#include<iostream>
using namespace std;

int main()
{
   double s1,s2,s3,avg;
  
   cout<<"Please enter the values of game scores :";
   cin>>s1>>s2>>s3;
  
   avg = (s1*0.2)+(s2*0.3)+(s3*0.5);   // Computing weighted average according to the game weightage
  
   if(avg >= 2000)
   {
       cout<<"Expert\n";
       cout<<"Congratulations! You are an expert! \n";
   }
   else if(avg >= 1800 && avg < 2000)
   {
       cout<<"Master\n";
       cout<<"Good Job!\n";
   }
   else if(avg >= 1500 && avg < 1800)
   {
       cout<<"Advanced\n";
       cout<<"Good Job!\n";
   }
   else if(avg >= 1000 && avg < 1500)
   {
       cout<<"Intermediate\n";
   }
   else if(avg < 1000)
   {
       cout<<"Beginner\n";
       cout<<"Keep on practicing!\n";
   }
   return 0;
}

Sample run# 1
600 1500 900
output : Intermediate

Sample run# 2
1800 1500 2000
output :Master
Good Job!
