function template

Write a function template contains that accepts an array of the parameterized type, the number of elements in the array (an integer), and a value of the parameterized type, and returns true if the value is in the array and false otherwise.

template<class T>
bool contains(T a[], int k, T p)
{
bool stat = false;
for(int i=0; i < k; i++)
{
if(a[i] == p)
{
stat = true;
}
}
return stat;
}

saying compiler error...help please

i think in line

Code:

---

bool contains(T a[], int k, T p)

---

you can insert

Code:

---

T a[10]

---

Or

Code:

---

  T *a

---

then malloc memory for *a

I suggest that you post the smallest and simplest program that demonstrates this error, and also post what is the error. From what I see, your function template could compile, so perhaps the error lies elsewhere.

Changing the declaration of parameter a to that won't make a difference, and in fact is wrong because it hints that the array is expected to have 10 elements when there is no such restriction.

That does not make sense: the function is supposed to search the array to check if it contains a value. Obviously, the array must already exist, otherwise the instructions would have mentioned populating the array in the function. Furthermore, malloc may be inappropriate to create objects of type T.
