Summary This assignment involves writing a computer program

Summary This assignment involves writing a computer program. The program will read in a text file of paired data values. The program will then test the values for a correlation, following the structure of a Hypothesis test as set out in this module and based on information supplied from your knowledge of the correlation as a statistical test. Input Two parallel lists of values are written in a text file ?inputl.txt?, which takes the following format, with all numerical values separated by tab characters or return characters. N (an integer value) (N values of the first variable in a row) (N values of the second variable also in a row) Purpose of the program Your program should do the following: 1. Read the two lists of values from the text file.

Solution

#include <stdlib.h>
#include <stdio.h>
#include <math.h>

main()
{
   FILE *input, *output;
   char ch;
   int N;
   int count = 0;
   int temp = 0;
  
   input = fopen(\"input1.txt\",\"r\");
   output = fopen(\"output1.txt\",\"w\");
   fscanf(input, \"%d\",&N);
  
   double first_var[N];
   double second_var[N];
      
   for(count = 1; count<N+1;count++)
   {
       fscanf(input, \"%lf\",&first_var[temp]);
       printf(\"%lf\ \", first_var[temp]);
       temp = temp+1;
   }
  
   temp = 0;
   for(count = N+2; count<=2*N+1;count++)
   {
       fscanf(input, \"%lf\",&second_var[temp]);
       printf(\"%lf\ \", second_var[temp]);
       temp = temp+1;
   }
  
   for(temp = 0; temp < N; temp++) fprintf(output, \"%lf %lf \ \", first_var[temp], second_var[temp]);
}
