InputParameters params; params.addParameter("time_step", 0.01); params.addParameter("num_iterations", 1000);
Teuchos::ParameterList simParams; simParams.set("num_particles", 1000); simParams.set("simulation_time", 10.0); simParams.set("use_gpu", true); InputParameters params(simParams);In this example, a ParameterList object from the Teuchos package library is created and three parameters are set with their corresponding values. Then an InputParameters object is constructed using this ParameterList. This code uses the Teuchos package library. In conclusion, InputParameters is a convenient data structure for handling user-defined input parameters in C++ programs, and its implementation can use various package libraries depending on the needs of the program.
