Array Count

[AmbiguousName]

hello guys... I have this array which has 5 elements in it like this.

int arr[] = {1,2,3,4,5};

Now how do I find the length of this array? thnx

Not completely sure what you mean, but try this: #define ARRAY_LENGTH(array) (sizeof(array) / sizeof(array[0])) and use it like: int my_array_len = ARRAY_LENGTH(arr);

Use the built-in macro: http://msdn.microsoft.com/en-us/library/ms175773%28v=vs.80%29.aspx[^]

The size of the array, or the number of elements?

Use sizeof(arr) / 4;

#include <stdio.h>

void main()
{

int arr\[\] = {1,2,3,4,5};

int x = sizeof(arr)/4;
printf("sizeof(arr) = %d \n", x );

}

int main() { int a[] = {1,2,3,4,5}; printf("%d",sizeof(a)/sizeof(int)); getch(); }
