When we use the Linux or UNIX operating system, we need to include “unistd.h” header file in our program to use thesleep ()function. While using the Windows operating system, we have to include “Windows.h” header to use the sleep () function. So in order to write a cross-platfor...
If you need more control over the precision of the converted string, you can combinestd::to_stringwith the<iomanip>header to set the desired precision using thestd::setprecisionmanipulator. Here’s an example of how to do that: #include<iomanip>#include<iostream>#include<string>using std::co...
Now we will write down the makefile for the above example. We will define variables to hold the values of compiler and compiler flags as shown below. CC = g++ CFLAGS = -wall -g Then we create the first target in our makefile i.e. the executable main. So we write a target with it...
Use std::setprecision and std::fixed to Round Floating-Point Number to 2 Decimals in C++Alternatively, one can utilize the std::setprecision function from the I/O manipulators’ library in conjunction with std::fixed. The latter is used to modify the default formatting for floating-point ...
Log4cplusneed to be initialized as follow: #include<log4cplus/logger.h>#include<log4cplus/configurator.h>{::log4cplus::initialize(); ::log4cplus::PropertyConfigurator::doConfigure("log4cplus_configure.ini");} This code should be put in the head of the main() or in your initializatio...
Probably there is no way to output long doubles. UPD: #include <iostream> #include <iomanip> using namespace std; int main() { long double d = 0.12345678910; cout << fixed; cout << setprecision(12) << d; return 0; } →Reply ...
Sure. I will keep kiss in mind as an alternative. Since I feel like I need to understand libraries better anyway, I will first try to get fftw running. As soon as I figure out the exact problem, I will update this post or write a more concrete question. ...
In this case if you already know the solution it would be really easy... Let me know if I had to write some code or if you can run the matrix I provided on your machines without trouble simply importing the txt files into a C array. Thanks Translate 0 Kudos Copy link Reply ...
If you are going to usemyFile.close();I would move it up to line 34 . The for loop looks like it should work, but I have no way to test it yet. I would more likely write the "cout" statement ascout <<cars[i].getCarIndex()..., but I did not see this function in the ot...
I want to re-code the ancient game Hunt The Wumpus. Therefore I want to connect the rooms of the cave to a dodecahedronal graph with a room at each corner. Some idea, how I could write an algorithm which produces such a polyhedron?
