Generally in c, this is how we find the length of an array arr:. The length is calculated by finding size of array using sizeof and then dividing it by size of one element of the array. To declare an array in c, a programmer specifies the type of the elements and the number of elements required by an array as follows −.

In The C Language, We Can Use The Sizeof Operator To Find The Array’s Size Or Length.

Method 1 to initialize a two dimensional array in c of size x * y, without using any nested brace, we can use the syntax below. The sizeof () function in c calculates the size in bytes of the passed variable or data type. If we divide the array’s total size by the size of the array element, we get the number of elements in the array.

Then The Value Of Len Is Displayed.

N = sizeof(arr) / sizeof(arr[0]); Size of char data type: The syntax that involves two (or more) consecutive empty square brackets [][] is never valid in c language.
