My code is stashed with hacks

    for(size_t i = 0; i < data_len; ++i)
        somedata[i] *= 2;

int myArray[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
const size_t arrLen = sizeof(myArray)/sizeof(myArray[0]);
myFunc(myArray), arrLen);
// ... etc

#if !defined(_countof)
#define _countof(_Array) (sizeof(_Array) / sizeof(_Array[0])) 
#endif

void myFunc(char somedata[])  // edited to remove * after char: see Richard's post below

void myFunc(char somedata[], size_t n)
