How to multiply all elements in an array

I found it difficult to multiply all my elements of an array. I am writing two arrays of elements, and after that I am merging those two arrays to one array of negative numbers. Later, I want to multiply all elements of that merged array. This is my try:

    int mul = 0;
    for (i = 0; i < negativecount; ++i)
    {
        mul = mul * merge[i];
    }
    cout << mul << endl;
}

And I am getting random numbers as the answer. How do I fix this problem?

Solution

  • The initial value of mul must be 1.
