How to send a copied file to a chosen destination and/or directory in C?

Question

I have trouble searching for a solution on how to send a successfully, copied file to a chosen destination and/or directory in C, instead of copying a file into the same destination. How do you do that? what should I do to fix this problem?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>

int main(int argc, char *file[])
{
    int ch;  //ch - character no.                               
    struct stat sb;
    FILE *source, *target;
    /* from http://stackoverflow.com/questions/30215462/how-to-get-the-source-  files-the-file-which-i-want-to-copy-and-the-copied-file/30217023#30217023 */
    if (argc <= 2) {
        printf("Enter source and destination file names\n");
        exit(EXIT_FAILURE);
    }

    if ( strcmp(file[1], file[2]) ==0 )
    {
        printf("the files are the same\n");
        exit(1);
    }
    /* if ( file[2] != NULL)
    {
        printf("the destination file exists\n");
        exit(1);
    }*/
    source = fopen(file[1], "r");//getting and opening source file
    if( source == NULL ) {
        printf("Press any key to exit...\n");
        exit(EXIT_FAILURE);
    }

    target = fopen(file[2], "w");//getting and opening destination file

    if( target == NULL ) {
        fclose(source);
        printf("Press any key to exit...\n");
        exit(EXIT_FAILURE);
    }

    while( ( ch = fgetc(source) ) != EOF )
        fputc(ch, target);

    fclose(source);
    fclose(target);
    printf("File copied successfully.\n");
    /* from http://stackoverflow.com/questions/30215462/how-to-get-the-source-files-the-file-which-i-want-to-copy-and-the-copied-file/30217023#30217023 */
    if (stat(file[1], &sb) == -1) {
        perror("stat");
        exit(1); //exit(EXIT_SUCCESS);
    }
    else
    if (chmod(file[2], sb.st_mode & 07777))//http://stackoverflow.com/questions/18032574/how-can-i-copy-permissions-from-a-file-that-already-exists
    {
        perror("chmod");
    }

    printf("Source File: %s, Inode number: %d, Mode: 0x%04X\n", file[1], (unsigned)sb.st_ino, (unsigned)sb.st_mode);

    if (stat(file[2], &sb) == -1) {
        perror("stat");
        exit(1);
    }

    char *str;
    str = (char *) malloc(15);
    strcpy(str, file[2]);

    if (stat(file[2], &sb) == -1) {//http://stackoverflow.com/questions/7430248/creating-a-new-directory-in-c
        mkdir(file[2], 0700);
    }
    printf("Destination File: %s, inode number: %d, Address = %u, Mode: 0x%04X\n", file[2], (unsigned)sb.st_ino, str, (unsigned)sb.st_mode);

    free(str);
    return 0;
