I'm brand new to C++ and am having trouble trying to get a function (which takes an array) to return an array. The function is a very basic sorting algorithm for an array of integers of size 4. What i have is below:
int[] sortArrayAscending(int arrayToSort[3]) {
int sortedArray[3];
sortedArray[0] = minOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
sortedArray[1] = lowerMidOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
sortedArray[2] = higherMidOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
sortedArray[3] = maxOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
return sortedArray;
}
I think i'm getting really confused with the syntax i need to use (the function calls to min, lower, higher, max all work fine.
I would really appreciate some help.
Thank you
EDIT2: Thank you for all the comments. I have now solved it thanks to @Rook's and @Bob Yoplait's answers. The code is used is:
int* sortArrayAscending(int arrayToSort[4], int sortedArray[4]) {
sortedArray[0] = minOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
sortedArray[1] = lowerMidOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
sortedArray[2] = higherMidOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
sortedArray[3] = maxOfFour(arrayToSort[0],arrayToSort[1],arrayToSort[2],arrayToSort[3]);
return sortedArray;
}
int _tmain(int argc, _TCHAR* argv[])
{
int testNumbers[4] = {8,14,1,27};
int testSorted[4];
sortArrayAscending(testNumbers,testSorted);
for (int i = 0; i < 4; i++) {
cout << testSorted[i] << endl;
}
system("pause");
return 0;
}
Thank you for all your help - now time to lookup vectors!
PS I appreciate @Luchian Grigore's solution is most likely the best practise way of doing things, but that wasn't specifically my question
