Found the solution.
The problem was that I was using maven to build the project and I was
building the jar with dependencies. This caused the dependencies that

There's no need for cin.ignore();
Simply write it as:

cin >> theSpeaker->phoneNumber;
cout << "

|My c program should be running in several threads using openmp but it isn't|
I guess there are only two possibilities for the issue.
shared_data->sh_rct == 1. In this case, there is nothing to run in
OpenMP runtime was told to limit the number of threads to only one.
The later can be caused by:
Prior call to omp_set_num_threads(1)
OMP_NUM_THREADS environment variable set to 1
Prior call to omp_set_dynamic(1) or OMP_DYNAMIC=TRUE in some cases
