Answer:
const int N = sizeof(a)/sizeof(a[0]);
Explanation:
Given
Programming Language: C
Name of Array: a
Required
Statement to declare constant N and calculate the number of array element
The single statement is as follows;
const int N = sizeof(a)/sizeof(a[0]);
What the statement does is that, it divides the size of the array by the size of the array data type on the system used in running the application;
Take for instance
The elements of array a is {1,2,3,7, 10} --- This is type integer
Let's assume that the size of integer datatype on my PC (for instance) is 4
That means the size of array will be 4*5 = 20
The number of array elements will be calculated by 20/4 = 5
