I hope this helps . Most of the time, one got to look at the actual problem. Parsing a packet protocol may or may not be easy, depending on the specification, but you can usually do better than throwing it all in a string... class UdpPacket
{
public:
UdpPacket(const char str[], size_t length);
uint16_t sourcePort() const { return mSourcePort; }
unit16_t destinationPort() const { return mDestinationPort; }
// ... The 3 other getters
private:
uint16_t mSourcePort;
uint16_t mDestinationPort;
uint16_t mLength;
uint16_t mCheckSum;
std::string mData;
}; // class UdpPacket
UdpPacket::UdpPacket(const char str[], size_t length):
mSourcePort(0), mDestinationPort(0), mLength(0), mCheckSum(0),
mData()
{
if (length < 8) throw IncompleteHeader(str, length);
memcpy(mSourcePort, str, 2);
memcpy(mDestinationPort, str, 2);
memcpy(mLength, str, 2);
memcpy(mCheckSum, str, 2);
mData = std::string(str+8, length-8);
} // UdpPacket::UdpPacket

A PHP function to convert decimal ASCII to ASCII char
Tag : php , By : Bobblegate

This might help you Your question is ambiguous in the sense that without any assumption, an input string can result in an exponential number of output strings that all satisfy the constraints. We make the assumption that with ASCII you mean the readable (not control-parts) of ascii. Thus any valid ascii value is between 32 and 128. As a result, you know that if the first two characters represent a value, strictly less than 32 it will be in the 100+ range. $s = "495051979899100";
$n = strlen($s);
$result = "";
for ($x=0; $x<=$n; $x += 2) {
$temp = intval(substr($s,$x,2));
if($temp < 32) {
$temp = intval(substr($s,$x,3));
if($temp > 128) {
die "Assumption error";
}
$x++;
}
$result .= chr($temp);
}
echo $result;

C : wrong char to ascii conversion (char from the extended ascii table)
Date : March 29 2020, 07:55 AM
This might help you Because char is from -127 to 127. You can't use extended ASCII table like that.
I suggest you use wchar instead. Check wchar.h and wctype.h manual.

Can my Android Studio project corrupt if I change a char to NON-ASCII char in android:label
Date : March 29 2020, 07:55 AM
seems to work fine Yes the app might not work if you're using non-ascii characters, but this is probably a Lint error so you can just disable that error. But if you're looking for a good practice, you should add this string to your language's values folder and you can just add translatable="false" if you don't want to enforce its translation. <string name="lapo" translatable="false"> Lapó </string>
