如何使用vc ++初始化float数组?

问题描述

我已初始化如下:

fvariable [100] = {0.0，0.0}在构造函数中，但是出现语法错误.

I have initialized as following:

fvariable[100] = {0.0, 0.0} in constructor but I got syntax error.


Is it not the right way to initialize it?

推荐答案

class MyClass
{
  float fvariable[100];

public:
  MyClass()
  {
    for (int n=0; n < sizeof(fvariable)/sizeof(fvariable[0]); n++)
    {
      fvariable[n] = 0.0;
    }
  }
};

:)

//declaration time
float fvariable[100] = { 0.0f };

//you can''t do that.
//fvariable[100] = { 0.0f };

//Or you can do as CPallini suggests:
for (int i = 0; i < 100; n++)
    fvariable[i] = 0.0f;

但是它们是其他方式...

But they are other ways...
