    copied!<p>I'm trying to do some practice programming and I've come to a, for me, a difficult problem.</p> <p>The problem is I'm supposed to write a program the will take the make and model of a car that was "entered" and place it in the structure, if the make an model are not there, otherwise it does nothing.</p> <p>This is what I have so far, and I keep getting errors:</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;string.h&gt; void addCar(struct car u, int* count, char *make[], char *model[]); struct car { char make[30]; char model[30]; }; int main(void) { struct car unique[10] = {{"Ford", "Explorer"}, {"Honda", "Civic"}, {"Honda", "Accord"}, {"Chevy", "Malibu"}}; int i, count = 4; addCar(unique, &amp;count, "Ford", "Mustang"); } void addCar(struct car u, int* count, char *make[], char *model[]) { } </code></pre> <p>The line that says <code>addCar(unique, &amp;count,...</code> it's saying "Argument type '<code>struct car'</code> is incomplete" and the last line says <strong>"conflicting types for addCar</strong>"</p> <p>Could you all give me a few pointers, please?</p> <p>EDIT:</p> <p>Okay, here is what my code is now, but I still can't get it to work. Any other suggestions would be appreciated!</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;string.h&gt; struct car { char make[30]; char model[30]; }; void addCar(struct car *u, int *count, char *make, char *model); int main(void) { struct car unique[10] = {{"Ford", "Explorer"}, {"Honda", "Civic"}, {"Honda", "Accord"}, {"Chevy", "Malibu"}}; int i, count = 4; printf("%s", unique[0].make); addCar(unique, &amp;count, "Ford", "Mustang"); } void addCar(struct car *u, int *count, char *make, char *model) { int i = 0; for (i; i &lt; *count; i++) { if ((u[i].make != make) &amp;&amp; (u[i].model != model)) { strcpy(u-&gt;make, make); strcpy(u-&gt;model, model); count++; } } for (i = 0; i &lt; *count; i++) printf("%s, %s", u[i].make, u[i].model); } </code></pre>
