Howq to get the ascii of a char ?

[yellowmat]

Hi everybody,

I have an integer value and I need to convert each integer digit value to an ascii code. For example if I have :


int intValue = -123;


i whish to have the following string :


QString asciiValue = "2D 31 32 33"


I is it possible to get the ascii code of a char ?

Thanks in advance.

#include <iostream>
using namespace std;
int main()
{
char x;

cout << "Enter character:\n";
cin >> x;
cout << "ASCII code for the letter is " << int(x) << ".\n";
return 0;
}


use ascii() to get the array of characters.

Maybe something like this:


int val = 123;
int rest;
int digit;
rest=val;
QVector<char> v;
while(rest>0){
digit = rest % 10; // last digit
rest = rest / 10;
v.push_front(digit+'0');
}

Then if you want their hex value, just sprintf them with "%x" formatting, like:


for(QVector<char>::const_iterator it = v.begin(); it!=v.end(); ++it){
::snprintf("%x", *it);
qDebug(qPrintable(hex));
}
Of course you can use QString::arg() for that.

You can also use QString methods directly like so:


int val = 123;
QString text = QString::number(val);
QStringList hex;
for(int i=0;i<text.size();i++){
hex << QString::number(text[i].toAscii(), 16);
}
