Question

Name this program one.c - This program takes two command line arguments: 1. an input filename 2. a threshold Your program will create two files: 1. even.txt - contains all integers from the input file that are even and greater than the threshold 2. odd. txt - contains all integers from the input file that are odd and greater than the threshold • The input file will exist and only contain a set of integers. It will always be valid data. • Output whitespace will be ignored. • Name the files even.txt and odd.txt. . Don't forget to close your files and follow the standard read pattern! Example: . /a.out input.txt 5 input txt (given) even txt (created) odd.txt (created) 1125 79 3 10 4 12 10 79 Example: -/a.out input2.txt 2 input2.txt (given) even.txt (created) odd.txt (created) 1 2 3 4 5 6 7 8 9 468 3579 272166. 1470084

in c prog only please!!

Answer 1

C PROGRAM:

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

//main
int main()
{
    //variables declaration thres for threshold value & x to read data from file
    int thres,x;

    //char type array to input file name and store
    char filename[200];
    printf("Enter the file name: ");
    scanf("%s",filename);    //filename input

    printf("Enter the threshold value: ");
    scanf("%d",&thres);      //threshold value input

    //opening and creating files
    FILE *fread;   //input file open
    fread  = fopen (filename, "r"); //here r keyword is to read from file

    FILE *feven;    //even number file
    feven  = fopen ("even.txt", "w"); //here w keyword is to write in file

    FILE *fodd;     //odd number file
    fodd  = fopen ("odd.txt", "w"); //here w keyword is to write in file

    //showing input values on screen
    printf("Input file values: ");

    //loop to read till EOF and evaluate all values from input file
    // and writing outputs in even.txt and odd.txt accordingly
    while((fscanf(fread,"%d",&x))!= EOF)  //EOF: end of file
          {
              printf("%d ",x);
              if(x>thres)  //checking threshold
              {
                  if(x%2==0)
                    fprintf(feven,"%d ",x);  //writing in even.txt
                  else
                    fprintf(fodd,"%d ",x);   //writing in odd.txt
              }
          }

          //closing all files
          fclose(fread);
          fclose(feven);
          fclose(fodd);

    printf("\n\n");


    return 0;
}

OUTPUT:

3 X C:\Users\NITISH\Music\BooleanDecision\main.exe Enter the file name: input.txt Enter the threshold value: 5 Input file values: 1 12 5 7 9 3 10 4 execution time : 9.736 s Process returned (0x0) Press any key to continue.
