huh?

Now, when u asked, i don't know how i know but i know if u know what i mean.

Yes, it does remain. If new operator is used u need to delete explicitly.

p.s. And yes, this does loop forever if functionCall() really returns 3

no way, variable is set to true, because functionCall()!=0 is true. in this case true means 1

fstream header will do. just include <ifstream>
then do
ifstream vname("filename");
vname >> array[i]; as many times as needed

or In #5 in the code you can change line 14 from if(str[i] < str[j]) to if(toupper(str[i]) < toupper(str[j])).

Well, i just transformed your own code. Used string str instead of char* a[100] and char tmp instead of char* tmp[100] (u need just one character to bubble-sort, not an array).
You would like to use...

Introducing bubble sort :)


#include <iostream>
#include <string>

int main()
{
std::string str;
std::cin >> str;

Look, you have that #include<string.h> right? So why don't you use c++ strings? It's like
string str;
str = "whatever"
and it's easier.
Now this

for(int b=0;b<=(strlen(a)-1);b++)
{
...

new allocates dynamic memory (did i choose the right words?).
