I need to make that when user introduces a number with ',' or '.' the number converts into decimal number. I have to do it with switch structure. For now I have the following code:

int main()
    int p=0,n=0,k=0,signo=1;
    float positivos[p] = {},negativos[n] = {};
    float valor, SumaPositivos=0, SumaNegativos=0,prueba=0;
    char caracter;
    std::cout.setf(std::ios::showpos); //ios está en el espacio de nombres std y por eso hay que ponerle std antes.
    cout << "Introduce your banking movement: " ;
    while (valor!=0)
            case '-':
            case ',':
            case '.':
            case '0':
            case '1':
            case '2':
            case '3':
            case '4':
            case '5':
            case '6':
            case '7':
            case '8':
            case '9':
                prueba=prueba*10+signo*(float (caracter-'0'));
            case '\n':
                    positivos[p] = prueba;
                    std::cout << prueba << "\n";
                else if(prueba<0){
                    negativos[n] = prueba;
                    std::cout << prueba << "\n";
                else if(prueba==0){
                cout << "Invalid character, introduce numbers.";
                caracter=' ';
