C++ 从XCode调试控制台打印C数组索引内容
我正在寻找一种将C样式数组索引的内容打印到XCode 4.5中的控制台窗口的方法。换句话说，当我的音频缓冲区（一个C数组）被浮点数据填充时，我会在填充后放置一个断点，我只想打印数组[]中内容的值。我尝试了以下方法：C++ 从XCode调试控制台打印C数组索引内容,c++,objective-c,c,audio,buffer,C++,Objective C,C,Audio,Buffer,我正在寻找一种将C样式数组索引的内容打印到XCode 4.5中的控制台窗口的方法。换句话说，当我的音频缓冲区（一个C数组）被浮点数据填充时，我会在填充后放置一个断点，我只想打印数组[]中内容的值。我尝试了以下方法： // Just an example of what I'm doing.

// Just an example of what I'm doing. The following is a buffer that I am declaring:
int total = 235377;
float tmpArr[total];
// gives me the first index [0] contents value only when I type this in the console window in Xcode
p tmpArr
// gives the following error:
// error: subscripted value is not an array, pointer, or vector
// error: 1 errors parsing expression
p tmpArr[3]
// gives me the address as expected
p &tmpArr
// the following seems to access contents but is casting them to ints and therefore truncating anything after the decimal...in audio programming, the float data is between 0 and 1 sooo....
frame variable -ffloat tmpArr
frame variable -ffloat tmpArr[3]
正如@Daniel Fischer指出的，在XCode控制台中键入p*（tmpArr+indexNumber）成功访问tmpArr[indexNumber]并将其打印到调试控制台。您是否尝试过
p*（tmpArr+3）
