Incrementing String value

[jsulm]

@Vineela Something like

QString str = "INKA010101002020";
QString subStr = str.right(3);
int number = subStr.toInt();
++number;
str = str.chopped(3) + QString("%1").arg(number, 3, 10, '0');

@jsulm well this was my answer

INKA01010100221.000000000000000000000000000000000000000000000000
I wanted 021 only the last three digits to get added

@Vineela no its not

show us what you're actually doing.

[jsulm]

@Vineela See the fix from @J-Hilk - for me it is working.

[Vineela]

@J.Hilk oh yes it worked not added QChar at last thanks.

[Vineela]

@J-Hilk , @jsulm well INKA010101001 this is my QString value i just want to add 001 to the last so that i get the final value INKA010101001001 like this.

[jsulm]

@Vineela And what is the problem? You can append a string easily to another one...

[Vineela]

@jsulm oh yes ive tried that i got INKA010101001\u0001 this
I've used this code

QString dd= store;
  dd.append(001);

[jsulm]

@Vineela said in Incrementing String value:

dd.append(001);

dd.append(QLatin1String("001"));

[J.Hilk]

@Vineela

//String concatenation

QString a("123");
QString b("001");
int num =1;

QString c = a + b == a.append(b) == a + QString::number(num).rightJustified(3,QChar('0'));

[Vineela]

@jsulm @J-Hilk sorry small change
dd.append("001");
just this added it worked fine.
