placement

I am having a problem with the placement new operator. I have two programs: Program1 (operator.cpp) and Program2 (main.cpp): Program1: operator.cpp void *operator new(size_t size) { void *p; cout << "From normal new" << endl; p=malloc(size); return p; } void *operator new(size_t size, int *p) throw() { cout << "From placement new" << endl; return p; } Here is the second program to which the first is linked: main.cpp: #include <new> int main() { int *ptr=new int; int *ptr1=new(ptr) int(10); } I am individually compiling operator.cpp and main.cpp as shown: operator.cpp: g++ -g -c -o operator

I'm using (maybe misusing?) a Polar chart to represent some data I have. I would like to have the labels, currently positioned right above the x-axis, to be above the segment of data. So right between the axis. I've found multiple articles on how to rotate everything but it always keeps the label right above the axis. The peace of code I have for the axis (if you need the whole definition/code, please say so): # Set axis names and orientation ax.set_theta_zero_location("N") ax.set_xticklabels(['Seg 1', 'Seg 2', 'Seg 3', 'Seg 4', 'Seg 5', 'Seg 6', 'Seg 7', 'Seg 8']) ax.set_ylim((0, 10.0)) ax

I stumbled upon this function in an answer to this question : /* Note: I've formatted the code for readability. */ const char * getString() { const char *x = "abcstring"; return x; } I was surprised to discover that returning a pointer to the literal string worked, and didn't segfault like I thought it would. I always assumed that literals were pushed on to the stack or put in some other temporary memory, but where limited to the scope of the function. But here it seems that they are more static than I had imagined. Are they then put into something sort of string pool that's global to the
