I'm experimenting with std::setprecision, is good to say how many decimals you want to show but... I have a problem. I realized that also affects other variables and not
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...

C++ program to find a particular element in an unordered map. Code: #include <iostream> #include <unordered_map> //use the namespace as std using namespace std; //code for unordered_map begins here int main(void) { //define the unordered_map ...

For example,if a rule specifies any dependency, then the make tool will include that dependency for compilation purposes. The make command is used in the makefile to build modules or to clean up the files. The general syntax of make is: ...
For our next example, we have a list of unsorted number values, and we will implement a simple sort function to sort these values and print; for that, the code is as follows. Code: #include <iostream> #include <algorithm> using namespace std; ...
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 ...
