Thread: Write a C program to write even and odd integers into different files.

Create three files namely all_numbers, odd_number and even_number.
Get the number of records and the numbers to store from the user.
Save all the numbers in “all_numbers” file. Read each number and check whether it is odd or even.
Store the odd numbers in odd_number file and even numbers in even_number file.
Finally, print the numbers stored in odd_number and even_number files.
The output of the program will look like this.

How many records that you want to store :41
2
3
4
The data are written too the respective files.

The even numbers are 2 4
The odd numbers are 1 3

Please help me on this.Thank you.

i don't have any code.i just want a c program and i want a c source code for Borland c++.Please tell me a program.

Code:

#include <stdio.h>
#include<conio.h>
#include<stdlib.h>
main()
{
   int n=0,i,n1;
   char ch;
   FILE *fptr,*fptr_e,*fptr_o;
   clrscr();
    fptr=fopen("C:/TCWIN45/BIN/all_num.txt","w");
    fptr_e=fopen("C:/TCWIN45/BIN/even.txt","w");
   fptr_o=fopen("C:/TCWIN45/BIN/odd.txt","w");
   if(fptr==NULL){
      printf("Error!");
        exit(1);
   }
   printf("How many record that you want to store : ");
   scanf("%d",&n);
   for(i=1;i<=n;i++)
    {
    scanf("%d",&n1);
    fprintf(fptr,"%d\n",n1);
    if(n1%2!=0)
    {
       fprintf(fptr_o,"%d\n",n1);
    }
    else
    {
       fprintf(fptr_e,"%d\n",n1);
    }
    }
printf("The data are written to the respective file\n\n");
printf("The Even Number are: \t");
fptr_e=fopen("C:/turboc++/even.txt","r");
while(ch=getc(fptr_e)!=EOF)
    {
    printf("%c\t",ch);
    }
fptr_o=fopen("c:/turboc++/odd.txt","r");
while(ch=getc(fptr_o)!=EOF)
    {
    printf("%c\t",ch);
    }
getch();
   fclose(fptr);


   return 0;
    }

And the output which i want is as follows:

How many records that you want to store :4

1
2
3
4
The data are written too the respective files.

The even numbers are 2 4
The odd numbers are 1 3

But it gives some error after entering 1 2 3 4 .Error i got is something "General Protection Exception Processor Fault".Pls tell me why i got this error & how to eliminate it.

Code:

#include <stdio.h>
#include<conio.h>
#include<stdlib.h>
main()
{
    int n=0,i,n1;
    char ch;
    FILE *fptr,*fptr_e,*fptr_o;
    clrscr();
    fptr=fopen("C:\\all_num.txt","w");
    fptr_e=fopen("C:\\even.txt","w");
    fptr_o=fopen("C:\\odd.txt","w");
    if(fptr==NULL){
        printf("Error!");
        exit(1);
    }
    printf("How many record that you want to store : ");
    scanf("%d",&n);
    for(i=1;i<=n;i++)
    {
    scanf("%d",&n1);
    fprintf(fptr,"%d\n",n1);
    if(n1%2!=0)
    {
        fprintf(fptr_o,"%d\n",n1);
    }
    else
    {
        fprintf(fptr_e,"%d\n",n1);
    }
    }
    fclose(fptr_e);
    fclose(fptr_o);
printf("The data are written to the respective file\n\n");
printf("The Even Number are:\t");




fptr_e=fopen("c://even.txt","r");
while((ch=getc(fptr_e)) !=EOF)
printf("%c",ch);
fclose(fptr_e);
printf("\nThe Odd Number are:\t");
fptr_o=fopen("c://odd.txt","r");
while((ch=getc(fptr_o)) !=EOF)
    printf("%c",ch);
fclose(fptr_o);
getch();
fclose(fptr);


return 0;
}

ok i wrote this final i even got the output but Output is not formatted accordingly.i want the following output:

The even numbers are 2 4
The odd numbers are 1 3

only these two lines i didn't get correctly.All others are fine.even i tried so many things but not getting the output as above for those two lines.

I would strongly recommend you actually listen to the advice laserlight gave you, and apply it - this would not only improve your code, but it would fix the problem you're asking about.

So you asked this questions elsewhere, took the crappy code that was handed to you, and claimed it as your own on yet another cross-post.

Then I'm guessing you tried to modify that crappy code you stole, and it still didn't working, leading to yet more cross-posting.

Have you tried sitting down with a book and just learning this stuff on your own?
