QString problem?

[askbapi]

QString userentry = ui->lineEdit->text();.

Now i need to loop through each character of the string and find the a matching charecter "A"

for(i=0;i<=20;i++)
{
if( userentry[i] == 'A' )
.............

}

I am getting error

What error do you get? use userentry.length() instead of fixed integer. See also QString::indexOf().

how can I get each character of Qsrting?

Native C++ style:
---------------------------------------------------
char userenter[30]; int i;

userenter[]="god is great";

for(i=0; i<= 29; i++)
{
cout << userenter[i] << endl;

}

how to do it with QString?

[Lykurg]

QString str = "fooBar";
for (int i = 0; i < str.length(); ++i)
  qWarning() << str.at(i); // or str[i]

QString str = "fooBar";
for (int i = 0; i < str.length(); ++i)
  qWarning() << str.at(i); // or str[i]

To copy to clipboard, switch view to plain text mode

You can also use QString::indexOf , cant you

QString userenter;
 
userenter ="god is great";
 
for(int i=0; i<= userenter.size(); i++)
{
    cout << userenter[i] << endl;
 
}

QString userenter;

userenter ="god is great";

for(int i=0; i<= userenter.size(); i++)
{
    cout << userenter[i] << endl;

By the way, your code is incorrect.
