Stringeling2

Making a second attempt.


string = Hello

'use code to remove 'O' from hello

string = Hell


, how can you achieve such without copying the original string.

What about replacing the last character with a null character?

Code:

---

#include <string.h>

char msg[] = "Hello";
msg[strlen(msg)-1] = '\0';

---

One solution is erase();

Code:

---

std::string sText = "NovemberX";
sText.erase( // Position
                    9,
                    // Number of elements.
                    1);

one avenue you could go down is create an

array [4] {"hello"}; //this will set it up as an array of 5 letters but we have set the element to 4. Now just creat an output for it and you should be ready to go.

cout << name_of_your_output;

I hope this gets you started in the right direction. Good Luck!!

( i solved it like this ) *take in context it's C++ Builder*


Since i had no idea how to (mouse click is the listbox value) i had to figure out how i could assign (as doggiesnot stated) ListBox1->Items->Strings[i] , Getting [i] was very difficult,but it was the right choise.

My code became the Following

Added 1 CSpinEdit1.

Code:

---

SpinEdit1->Value = ListBox1->ItemIndex;
Edit4->Text = ListBox1->Items->Strings[CSpinEdit1->Value];

---

This gave a clean string without the garbage.

So instead of trying to delete the separators and since i invested much time in getting code trying to erase newline's , i ditched that idea did like above, and came to a solution.

Thank you so much. And also for everyone elses views in this.
