enter image description here I’m trying to know how link order affect the efficiency of program. Currently, I can do that: test.h->test.h.gch and test.cpp/main.cpp->.ll->optimization->.s->.o file and link these two .o file to a executable file. But is the order of these two .o files depending on my input? Or llvm compiler will determine the link ..
if there any way to avoid this pattern (or be more concise) every time you get a pointer from a function (this happen a lot in my program): type *p = Afunction(); assert (p != nullptr); if ( p==nullptr ) { return; } because I don’t want my release software to crash if I receive ..
#include <iostream> using std::cout; using std::endl; int main(void) { std::string fx = "6x^2+6x+4"; int part1 = fx[0] * fx[3]; cout << fx[0] << endl; cout << fx[3] << endl; cout << part1; } So I have this string and fx[0] and fx[3] are obviously integers, when I print them to the console they print out ..
Ive been following along with some c++ tutorials on youtube and I cant seem to get this code to work, I use code blocks and this person uses visual c++. Is there a difference between them somehow? before I did cin >> std::Asalary; she asked what whould happen if you ran this code, she got ..

I have a C++ wrapper that calls Java functions of a Java SDK using JNI. In the Java code there is a generic class, for example let’s call it MyClass, that is defined like this: public class MyClass<T> extends HashMap<String, T> { … } In the C++ code I am calling a Java function using ..
I am trying to make my program able to handle window resizing without losing the aspect ratio with little luck. Most online searches led me to old questions using legacy code while I am working on OpenGL 3.3. So far what I have tried is using glfwSetWindowSizeCallback and glfwSetWindowSize but end up with the image ..
I am working on 3D point cloud object tracking(a cylindrical object) using particle filter in PCL(Point Cloud Library). The documentation does not quiet explains about the parameters on how it influences the results. I have done some study about the particle filter, but most of the parameters particle filter and coherence(I suppose the coherence here ..
