How can I correctly increase the stack available for a program using Bloodshed Dev C ++ or Code :: Block? I run a simple bubble sort and quick, but it works, but when I changed the stack in Code :: Block (learned as above here ), it made my program crash even faster, despite the use of a much larger than expected, location. Initially, the program crashes when sorting 64K random integers (using a function rand()). Now its crashing at 32K. im getting the error:Process returned -1073741571 (0xC00000FD)
the program really works faster without changing the stack, assuming I'm doing it right. gcc -Wl,--stack,1099511627776
I can't figure out how to change it at all in Dev C ++
What should I do? is there any way to change the stack inside the code itself? here is im code using for bubble and quicksort. There are two of them: one with vectors, the other with arrays. I think bubble grade. must be correct. quick variety, I'm not so sure. sorry if its a little dirty
vector <int> v_bubble(vector <int> array){
if (array.size() < 2){
return array;
}
int s = 1;
while (s){
s = 0;
for (unsigned int x = 0; x < (array.size() - 1); x++){
if (array[x] > array[x + 1]){
int t = array[x];
array[x] = array[x + 1];
array[x + 1] = t;
s = 1;
}
}
}
return array;
}
void a_bubble(int array[], int size){
int s = 1;
while (s){
s = 0;
for (int x = 0; x < (size - 1); x++){
if (array[x] > array[x + 1]){
int t = array[x];
array[x] = array[x + 1];
array[x + 1] = t;
s = 1;
}
}
}
}
vector <int> v_quick(vector <int> array){
if (array.size() < 2){
return array;
}
vector <int> left;
vector <int> right;
int p_location = array.size() / 2 - 1;
int pivot = array[p_location];
for(unsigned int x = p_location; x < array.size() - 1; x++){
array[x] = array[x + 1];
}
array.pop_back();
for(unsigned int x = 0; x < array.size(); x++){
if (array[x] <= pivot) {
left.push_back(array[x]);
}
else if (array[x] > pivot){
right.push_back(array[x]);
}
}
vector <int> p;
p.push_back(pivot);
return combine(combine(v_quick(left), p), v_quick(right));
}
int a_quick(int array[], int size, int l_index = -1, int r_index = -1){
if (size < 2){
return array[size];
}
array[size] = array[size];
int left[size];
int right[size];
l_index = 0;
r_index = 0;
int p_location = size / 2 - 1;
int pivot = array[p_location];
for(int x = p_location; x < size - 1; x++){
array[x] = array[x + 1];
}
size--;
for(unsigned int x = 0; x < size; x++){
if (array[x] <= pivot) {
left[l_index] = array[x];
l_index++;
}
else if (array[x] > pivot){
right[r_index] = array[x];
r_index++;
}
}
return a_quick(left, l_index, l_index, r_index) + pivot + a_quick(right, r_index, l_index, r_index);
}
the rest of the code simply generates arrays and vectors with 32, 64 and 128 k elements, sorting them using the above code and returning the time. that part im pretty sure i didn't mess up
my main basically just
start = clock();
a_quick(array1, 32000);
end = clock();
cout << "\nQuick Sort\tArray\t32000\t" << ((double) end - start)/CLOCKS_PER_SEC << " seconds\n";
again and again
