Arrays have 0 as the first index, not 1

If the size of an array is n, to access the last element,

Address of m[0] is 2120d and m[1] is 2124d

float u[2][4][3];

Passing array elements to a function is similar to

example m[0]

n-1

This is because size of a float is 4 bytes

the array can hold 24 elements
