Please find the following explanation on the given query.

Answer:

When you want to verify whether the function return has any value is, what you can do is simply use "if ((lex.addtoken(analisis.Type.Words_Reserved_Planificador))&&(lex.addtoken(analisis.Type.Symbol_Two_Points)))" by removing true as the return type.

In this case what ever the return type, other than void, it will execute the instructions from if block.

In case of void or 0, it will execute the else block..

if ((lex.addtoken(analisis.Type.Words_Reserved_Planificador))&&(lex.addtoken(analisis.Type.Symbol_Two_Points)))
{

instruccions

}else{

Console.WriteLIne("Error :(");

}
