11B. Simple C++ Programming Two Dimensional Array

Compile and run the following program to understand what it does. // This progra m will ask a runner for her/his fastest 3 times for 4 // different distances and will display them using a 2-D array. #include using namespace std /a function that returns a distance based on the choice i int find_distance(int i int main() int i, j double data [4][3 I/This arraywill keep 12 values in 4 rows and 3 columns // 4 events and 3 times for each one of the events for(i :0; i

Explanation / Answer

#include<bits/stdc++.h>
using namespace std;

int find_distance(int i)
{
   switch(i)
   {
       case 0:
       //100 m
       return 100;
       break;

       case 1:
       //150 m
       return 150;
       break;

       case 2:
       //200 m
       return 200;
       break;

       default ://400m
       return 400;

   }
}
int main(int argc, char const *argv[])
{
   int i,j;

   int distance[4];
   double data[4][3]; //this array will keep 12 values in 4 rows and 3 column
   //4 events and 3 times for each time

   for(i=0;i<4;i++)
   {
       distance[i]=find_distance(i);
       cout<<" Enter your 3 best runing times for"<<distance[i]<<"m ";

       for(j=0;j<3;j++)
       {
           cout<<"Enter a time (in seconds):";
           cin>>data[i][j];
       }
   }

   cout<<"Here are your 3 best times:";

   for ( i = 0; i < 4; ++i)
   {
       cout<<" Distance : "<<distance[i]<<"m ";

       for (j = 0; j < 3; ++j)
       {
           cout<<data[i][j]<<" ";
       }
       cout<<endl;
   }

   for ( i = 0; i < 4; ++i)
   {
       cout<<" Distance : "<<distance[i]<<"m ";

       double max=0;
       double min=9999;
       for (j = 0; j < 3; ++j)
       {
           if(max<data[i][j])
               max=data[i][j];
           if(min>data[i][j])
               min=data[i][j];
       }

       cout<<"Worst time "<<max<<endl;
       cout<<"Best time "<<min<<endl;
       cout<<endl;
   }
   return 0;
}
