int main(int argc, char const *argv[])

{

    

    FILE *in = fopen("copy.c","r");

    FILE *out = fopen("copy_1.c","w+");

    if(in == NULL || out == NULL){

        perror("open file error");

        exit(0);

    }



    int size = 20;

    char buf[20];

    while(fgets(buf,20,in) != NULL){

        fputs(buf,out);

    }



    fclose(in);

    fclose(out);





    return 0;
