pass array as reference c++ code example

Example 1: array as parameter c++

void myFunction(int param[]) {
   .
   .
   .
}

Example 2: passing array to function c++ pointer

void generateArray(int *a, int si)
{
    for (int j = 0; j < si; j++)
        a[j] = rand() % 9;
}

int main()
{
    const int size=5;
    int a[size];

    generateArray(a, size);

    return 0;
}

Example 3: array reference argument

template<typename T, size_t N>
void foo(T (&bar)[N])
{
    // use N here
}
