Thread: make a new entry in C

Code:

struct pqueue
{
    int numEntries;
    struct entry entries[10];           
    }
pqueue;
 
case 'e':
void enqueue(struct pqueue*pqueue, struct entry entry)
         {
    if (pqueue->numEntries == 10)
    {
        printf("priority queue already full!");
        return;
    }
    else
...

i try to make a priorityqueue and after the else there should follow a code where i create a new entry and obviously numentries should increase by 1 and if it worked well a text should be displayed "a new entry has successfully been added"
how do i do this?
