Question

All code must be in C++ using G++ compiler

write a program that performs the following Read 16 integer numbers from an input file Numbers.txt (You can manually create this file first and fill it with any sixteen integer values written one below the other so that reading them through code becomes easy) Store them in 4x4 two dimensional array (also known as matrix) named values. Set of 4 numbers should belong to each row as you keep reading the input file. Display the contents of the two dimensional (2D) array using nested for loops in the form of square matrix. (Always remember this) Create a function stats() that takes the two dimensional array as parameter from main() and computes Column 1 sum, Column 2 average, Row 3 minimum, and Row 4 maximum.

Explanation / Answer

Program:-

#include<iostream>
#include<fstream>
using namespace std;
void stats(int values[4][4])
{
   int sum1=0;
   for(int i=0;i<4;i++)
       sum1+=values[i][0];       //column 1 sum
   cout<<"Column 1 sum is :"<<sum1<<endl;
   int avg;
   int sum2=0;
   for(int i=0;i<4;i++)
       sum2+=values[i][1];       //column 1 sum
   avg=sum2/4;       //column 2 average
   cout<<"Column 2 average is :"<<avg<<endl;
   int min=9999;
   for(int i=0;i<4;i++)
       if(min>values[i][2])
           min=values[i][2];   // find minimum
   cout<<"Column 3 minimum is :"<<min<<endl;
   int max=-1;
   for(int i=0;i<4;i++)
       if(max<values[i][3])
           max=values[i][3];   // find maximum
   cout<<"Column 4 maximum is :"<<max<<endl;
}
int main()
{
   fstream file("Numbers.txt");   //opening file
   int values[4][4];  
   for(int i=0;i<4;i++)
       for(int j=0;j<4;j++)
           file>>values[i][j];   //reading file to array
   for(int i=0;i<4;i++)
   {
       for(int j=0;j<4;j++)
           cout<<values[i][j]<<" ";   //printing values
       cout<<endl<<endl;
   }
   stats(values);
   return 0;
}

output:-

41 54 12 3

2 56 14 52

78 91 88 22

6 7 59 42

Column 1 sum is :127
Column 2 average is :52
Column 3 minimum is :12
Column 4 maximum is :52
