	int iArr[10];
	float fArr[5];
	char cArr[50];
	
	printf("Total elements in iArr: %d\n", ARRAY_LEN(iArr, int));
	printf("Total elements in fArr: %d\n", ARRAY_LEN(fArr, float));
	printf("Total elements in cArr: %d\n", ARRAY_LEN(cArr, char));
	
	return 0;
}

Output

Total elements in iArr: 10
Total elements in fArr: 5
Total elements in cArr: 50
