float waveform = getParameter(6);
switch(waveform){
case 1: Sine signalGenerator
break;
case 2: SawWave signalGenerator
break;
case 3: SquareWave signalGenerator
break;
default: Sine signalGenerator
}
有关如何对其进行排序的任何建议都会很棒!提前谢谢!
这是真正的代码:
float waveform = getParameter(6);
switch(waveform)
{ case 1: Sine signalGenerator break;
case 2: SawWave signalGenerator break;
case 3: SquareWave signalGenerator break;
default: Sine signalGenerator
}
答案 0 :(得分:2)
你想要的可能就是:
int waveform = (int) getParameter(6);
WaveBase* sigGen;
switch(waveform) {
case 1: sigGen = new Sine; break;
case 2: sigGen = new SawWave; break;
case 3: sigGen = new SquareWave; break;
default: sigGen = new Sine;
}
// use sigGen here
delete sigGen;
这假设Sine,SawWave和SquareWave有一个共同的基础(他们应该)
并且它的析构函数是虚拟的(它应该)
