How would you initialize the size of an array in C?
Initializer List: To initialize an array in C with the same value, the naive way is to provide an initializer list. We use this with small arrays. int num[5] = {1, 1, 1, 1, 1}; This will initialize the num array with value 1 at all index.
What is maximum array size in C?
There is no fixed limit to the size of an array in C. The size of any single object, including of any array object, is limited by SIZE_MAX , the maximum value of type size_t , which is the result of the sizeof operator.

How do you declare an array size in C?
The arraySize must be an integer constant greater than zero and type can be any valid C data type. For example, to declare a 10-element array called balance of type double, use this statement − double balance[10]; Here balance is a variable array which is sufficient to hold up to 10 double numbers.

How do you find the size of an array in bytes?
To determine the size of your array in bytes, you can use the sizeofoperator: int a; size_t n = sizeof(a); On my computer, ints are 4 bytes long, so n is 68.
How do you find the number of elements in an array?
To determine the number of elements in the array, we can divide the total size of the array by the size of the array element. You could do this with the type, like this: and get the proper answer (68 / 4 = 17), but if the type of a changed you would have a nasty bug if you forgot to change the sizeof (int) as well.
What are the three sizes of an array?
From an array we have three sizes which we might want to know: 1 The size of the elements of the array 2 The number of elements in the array 3 The size in bytes that the array uses in memory More
