Hi,
as to questions 1/2 that depends on your O/S and compiler. I do not believe you can change the output color in a Windows command prompt on a character-by-character basis but probably somebody else corrects me here.
question 3:
the code fragment above has a few flaws.
1) you do not allocate memory for your string x which causes memory faults
2) you cannot add pointers in the way you do (x + x) is impossible
try to use the STL:
#include <string>
using namespace std;
string f(int len, char c)
{
string reval("");
for(int i = 0; i<len; i++)
{
reval += c;
}
return reval;
}
Careful! you have to fill some gaps...
Cheers,
D
