Std::string temp = str.substr(pos1, pos2-pos1); _widget_base = new char[temp.length()+1This is a const char * value

String ....
String temp = mystring.Replace("\n", "");
Are you sure there are actual \n new lines in your original string?
string temp = mystring.Replace("\n", " ");
String.Replace('\n, string) override, it should work.
This should work.

Your returning corrupted memory, thats why

I think the problem is that your char temp[0] is defined inside the function (local to the function that was caused.

I have tried

I want 4 but it gives me ascii value 52

The atoi() version isn't working because atoi() operates on strings... .
[10]; char temp = a[0]; int temp2 = temp - 0; b[0] = temp2;
with the simpler:
char a[] = "4x^0"; intYou need to do:
int temp2 = temp - '0';
instead.

Do you really need a copy? You could just make a new array pointing into the original strings:

The last line doesn't compile. I also tried &(inst->name) with no luck. The error I get is:
Error: char is not a structure type.

For example, this code works fine for me:

Gchar and char are for all intents and purposes the same.
I don't think your problem lies where you think it does .
Use gchar instead of char in struct.

I am trying to work with an array of char pointers.
Let's say I dynamically declare such an array like so:

Or just
