linux初学者的程序疑问

在cygwin下执行如下程序：
#include <unistd.h>
#include <stdlib.h>

int main()
{
        if ((write(1,"here is some data\n",1)!=1
                write(2,"A write error has occurred on file descriptor 1\n",46);
                exit(0);
}

执行失败，报如下错误：
$ ./simple_write.c
./simple_write.c: line 4: syntax error near unexpected token `('
./simple_write.c: line 4: `int main()'

程序怎么会将数字变成表情了呢? 重新贴一遍
#include <unistd.h>
#include <stdlib.h>

int main()
{
        if ((write(1,"here is some data\n",1)!=1
                write(2,"A write error has occurred on file descriptor 1\n",46);
                exit(0);
}
