qstring insert character

To insert a character into a QString in C++, you can use the insert() function. Here are the steps to follow:

1. First, determine the position at which you want to insert the character. You can specify the position using an index, where 0 represents the beginning of the QString.

2. Next, specify the character that you want to insert into the QString.

3. Finally, call the insert() function on the QString object, passing the index and the character as arguments.

Here is an example:

QString str = "Hello world!";
int index = 5;
QChar character = '-';
str.insert(index, character);

In this example, the character '-' will be inserted at position 5 in the QString "Hello world!". As a result, the QString will become "Hello-world!".

Note: The insert() function modifies the original QString. If you want to create a new QString with the inserted character, you can assign the result of the insert() function to a new QString variable.
