Question

The purpose of this assignment is to process rat exam data and calculate a ratIQ for each rat. Input: The user will be put the data for the rats in a text file named "test.txt" (here is an example that you can use). The first line of the input file will be the number of rats who took the test. Each line after that will contain a name (string) a number of correct test answers (int) and the number of seconds it took to take the exam (int). Each piece of data will be separated by one blank space. For example: 4 George 24 34 Jane 24 17 Joan 30 32 Phil 25 29 Processing: First the program will read in the number of tests. Then for each test the program will read in the name and calculate the rat's IQ score using the following criteria. The rat gets 10 points for each correct answer and an additional 5 points if he/she took less than 30 seconds to complete the exam. For the data above, George would have a ratIQ of 240 and Jane would have a ratIQ of 245. Output: The program will print one line of output for each rat that contains the rat's name and ratIQ score.For the above input, the output could look like this: George has a ratIQ of 240. Jane has a ratIQ of 245. Joan has a ratIQ of 300. Phil has a ratIQ of 255.

Explanation / Answer

C++ code:

#include <bits/stdc++.h>
using namespace std;
int main()
{
   string line;
   ifstream myfile ("test.txt");
   if (myfile.is_open())
   {
       getline (myfile,line);
       int n = atoi(line.c_str() );
       std::vector<string> names;
       std::vector<int> IQ;
       // std::vector<int> Time;
   while ( getline (myfile,line) )
   {
   string buf; // Have a buffer string
   stringstream ss(line); // Insert the string into a stream
   vector<string> tokens; // Create vector to hold our words
   while (ss >> buf)
   tokens.push_back(buf);
   names.push_back((tokens[0].c_str() )) ;
   int iq =0 ;
   int testcases = atoi(tokens[1].c_str() );
   int t = atoi(tokens[2].c_str() );
   if( t<=30)
   {
       iq = 10*testcases + 5;
   }
   else
   {
       iq = 10*testcases;
   }
   IQ.push_back(iq) ;
   }
for (int i = 0; i < n; ++i)
{
       cout << names[i] << " has a ratIQ of " << IQ[i] << endl;
}  
   myfile.close();
   }
   else
   {
   cout << "Unable to open file" << endl;
   exit(1);
   }          
   return 0;
}

test.txt

4
George 24 34
Jane 24 17
Joan 30 32
Phil 25 29

Sample Output:

George has a ratIQ of 240
Jane has a ratIQ of 245
Joan has a ratIQ of 300
Phil has a ratIQ of 255
