A file name DATA contains a series of integer numbers. Code a program to read these numbers and then write all ‘odd’ numbers to a file to be called ODD and all ‘even’ numbers to a file called EVEN.

#include<stdio.h>
#include<STDLIB.H>
main()
{
    FILE *f1,*f2,*f3;
    char c[1];
    int x;
    f1=fopen("data.txt","r");
    f2=fopen("odd.txt","w");
    f3=fopen("even.txt","w");

    while((c[0]=getc(f1)) != EOF)
    {
        x = atoi(c);
        if(x%2==0)
            putc(c[0],f3);
        else
            putc(c[0],f2);

    }
    fclose(f1);
    fclose(f2);
    fclose(f3);
}
