Number of elements in float array in C -
i have array of float in c. length of array depends of user input. need find out number of elements in array. example:
float a[10] = {3.1314, 1.5131, 9.133, 10.333}
how can check number of elements? sizeof(a)/sizeof(a[0]) give max number of elements (10 in case).
the number of elements in array of type t[n]
n
definition. array, of type float[10]
, has 10 elements, first 4 set values, rest set 0.0f
. if want check how many elements have been set, you'll have set rest sentinel value not valid value "set". or can keep track of number of set elements separately.
