How to grab a JSON file and decode into C++ ? read the Json file in C++

Question

I have a file JSON with employee data and wish to read this file in C++ to pass para a flash drive and export this file, how to proceed? Follows file JSON:

":"Alexandre N. da C.Neves","ID":"213","PIS":"00000000","Time":1456229448}...

and the program in C++ more or less like this:

typedef struct  funcionario // struct com 100 elementos
{
    char CodBarras[11];
    char BioDados[512];
    char Passwd[11];
    char MiFareDado[21];
    char Nome[53];
    char ID[11];
    char PIS[13];
    char Aux[5];
    long int Tempo;
}functionaries[100];   // array para rodar essa struct 100x 

the program has to load the JSON file and load into Struct.

thanks in advance
