C program to concatenate two files

Write a C program to concatenate two files.

  #include <stdio.h>
  #include <string.h>
  #define MAX 256

  int main() {
        int ch;
        FILE *fp1, *fp2, *fp3;
        char fname1[MAX], fname2[MAX], output[MAX];

        /* get the first file name from the user */
        printf("Enter your first file name:");
        fgets(fname1, MAX, stdin);
        fname1[strlen(fname1) - 1] = '\0';

        /* get the second file name from the user */
        printf("Enter your second file name:");
        fgets(fname2, MAX, stdin);
        fname2[strlen(fname2) - 1] = '\0';

        /* get the output file name from the user */
        printf("Enter your destination file name:");
        fgets(output, MAX, stdin);
        output[strlen(output) - 1] = '\0';

        /* open the first file in read mode */
        fp1 = fopen(fname1, "r");

        /* error handling */
        if (!fp1) {
                printf("Unable to open the file %s\n", fname1);
                return 0;
        }

        /* open the second file in read mode */

        fp2 = fopen(fname2, "r");

        /* error handling */

        if (!fp2) {

                printf("Unable to open the file %s!!\n", fname2);

                fclose(fp1);

                return 0;

        }

        /* open the output file in write mode */

        fp3 = fopen(output, "w");

        /* error handling */

        if (!fp3) {

                printf("Unable to open the file %s!!\n", output);

                fclose(fp1);

                fclose(fp2);

                return 0;

        }

        /* copy the contents of first file to output file */

        while (!feof(fp1)) {

                ch = fgetc(fp1);

                if (ch != EOF) {

                        fputc(ch, fp3);

                }

        }

        /* copy the contents of second file to output file */

        while (!feof(fp2)) {

                ch = fgetc(fp2);

                if (ch != EOF) {

                        fputc(ch, fp3);

                }

        }

        /* close the opened files */

        fclose(fp1);

        fclose(fp2);

        fclose(fp3);

        return 0;

  }

  Output:

  jp@jp-VirtualBox:~/$ cat data.txt 
  Take up one idea. Make that one idea your life -
  think of it, dream of it, live on that idea. Let 
  the brain, muscles, nerves, every part of your 
  body, be full of that idea, and just leave every 
  other idea alone. This is the way to success.

  jp@jp-VirtualBox:~/$ cat editMe.txt 

  All knowledge that the world has ever received 
  comes from the mind; the infinite library of the 
  universe if our own mind

  jp@jp-VirtualBox:~/$ ./a.out
  Enter your first file name: data.txt
  Enter your second file name: editMe.txt
  Enter your destination file name: output.txt

  jp@jp-VirtualBox:~/$ cat output.txt
