Here in this blog i will take help you to how to implement priority queue on pairs using custom comparators, You will have difficult finding this on internet as it took a lot of effort to find the correct working code which works for -std=++14 compiler of g++. typedefpair<int,int>pd;...
Use thecontainsMember Function to Check if the Given Element Exists in a Map in C++ If the user needs to confirm if the pair with the given value exists in themapobject, one can utilize the member functioncontains. The function has been part of thestd::mapcontainer since the C++20 versio...
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...
void* in_p = static_cast<void*>(row.data()); std::vector<double> out(1, 0); double* out_result = static_cast<double*>(out.data()); int64_t out_len; res = LGBM_BoosterPredictForMat(handle, in_p, C_API_DTYPE_FLOAT32, 1, 40, 1, C_API_PREDICT_NORMAL, 50, "None", &out...

Use theinsertMember Function to Insert an Element Into Set in C++ Theinsertfunction has multiple overloads, but we utilize the version that takes a single argument representing the element to be added to the set. This overload ofinsertreturns thestd::pairobject of iterator and thebool. ...

to use function template argument deduction:std::make_pair(11, 22)returnsstd::pair<int, int>. Like most workarounds, this is problematic for a few reasons: defining such helper functions often involves template metaprogramming (std::make_pair()needs to perform perfect forwarding and decay, ...
Use std::pair to Return Multiple Values From a Function in C++std::pair is provided the C++ standard library, and it can store two heterogeneous objects like a pair. Thus, we can reimplement the previous example without defining our custom struct as the std::pair has already extensive functi...
