怎么会出现10进制和16进制乱用的问题？在线等待

Question

我定义了一个数组 BYTE receivedata1【50】，在调试过程中receivedata1[49]应该为10，但是它好像是receivedata1[32]才是10（它把50转换为16进制了），而receivedata1【50】为0，这是怎么回事？哪位高手能告诉我。

Answer 1

int rec_length1,rec_length2;
BYTE receivedata1[50],receivedata2[50],receivedatatemp1[100],receivedatatemp2[100];
    for(BYTE kk=0;kk<100;kk++)
{
receivedatatemp1[kk]=0;
receivedatatemp2[kk]=0;
}
for(kk=0;kk<50;kk++)
{
receivedata1[kk]=0;
receivedata2[kk]=0;
}
//此处取串口的值
rec_length1=ReadComm(m_hSlave[0],receivedatatemp1,100);
rec_length2=ReadComm(m_hSlave[1],receivedatatemp2,100);
    {   
for(BYTE position=0;position<50;position++)
{
if((receivedatatemp1[position]==0x8e)
&&(receivedatatemp1[position+1]==0)
&&(receivedatatemp1[position+2]==1)
&&(receivedatatemp1[position+49]==0x8f))
{
for(BYTE datanumber=0;datanumber<50;datanumber++)
receivedata1[datanumber]=receivedatatemp1[position+datanumber];
break;
}
else
rec_length1=0;
}
}
//这里判断值，调试时receivedata1[0x31]结果正好是我要的第50个值，而receivedata1[50]不是
if((receivedata1[0]!=0x8e)||
(receivedata1[1]!=0)||
(receivedata1[2]!=1)||
(receivedata1[47]!=High)||
(receivedata1[48]!=Low)||
(receivedata1[49]!=0x8f))
{
SerialState1=FALSE;
}

Answer 2

0x31=49
0x32=50
vc从零开始计数的，
你的第1个是他的 receivedata1[0]；也就是 receivedata1[0x0]；
你的第2个是他的 receivedata1[1]；也就是 receivedata1[0x1]；
你的第3个是他的 receivedata1[2]；也就是 receivedata1[0x2]；
...
你的第49个是他的 receivedata1[48]；也就是 receivedata1[0x30]；
你的第50个是他的 receivedata1[50]；也就是 receivedata1[0x31]；有问题吗？
我看没问题。

你的第50个是他的 receivedata1[49]；也就是 receivedata1[0x31]；
