Can someone tell me why my print array method won't print strings.
It works with an int array, but only prints a few strings.
template < typename T >
void printArray(T * const array, int size)
{
for (int i=0; i < size; ++i)
cout << array[i] << ' ';
cout << endl;
}//printarrayany help would be great thanks.
OK i found out that when i use endl instead of ' ' its prints. But i want them all on one line.
Does anyone know what could be happening?
Any info would be great thanks.
I think it is because of buffering of cout. A call cout.flush() may help. (I didn't try it. So pls excuse if it is wrong)
hi
Thanks for the reply.
I've already tried flush. (cout << array << flush << ' ') but it didn't work.
I also found out that you only have to put a new line character ('\n') at the end to get it working. But as i said i need it on one line only. Any more ideas?
sorry i ment:
cout << array << ' ' << flush;
i have also tried:
cout << array << ' ';
cout.flush();
I just tried it in VC++ 8 and it works fine for me. his is the program I tried.
#include <iostream>
#include <string>using namespace std;
template < typename T >
void printArray(T * const array, int size)
{
for (int i=0; i < size; ++i)
cout << array << ' ';
cout << endl;}//printarray
int main(void)
{
string array[] = {"abc", "pqr", "xyz"};
printArray<string>(array, 3);
return 0;
}
OK, maybe I should give you a bit more info sorry.
Im using cygwin and the GCC compiler.
Also I'm getting the values for the array from a text file. Then sorting the array using a shell sort, then printing it.
here is the file input method:
void processFile_strings(const char * fileName, int &linecount, string *strptr)
{
string str;//for reading each line
linecount = 0;
ifstream inFile(fileName);//open file
if (inFile.fail()){
cout << fileName << " " << strerror(errno) << endl;
exit (1);
}
else
{
while(true)
{
getline(inFile, str);
if (!commentLine((char*)str.c_str()))
{
*strptr = str;
linecount++;
*strptr++;
}
if(inFile.eof())break;
}
}
inFile.close();//close file
}//processFile_stringssorry about the indentation
void processFile_strings(const char * fileName, int maxData, int &linecount, string *strptr)
{
string str;//for reading each line
linecount = 0;
ifstream inFile(fileName);//open file
if (inFile.fail()){
cout << fileName << " " << strerror(errno) << endl;
exit (1);
}
else
{
while(true)
{
getline(inFile, str);
if (!commentLine((char*)str.c_str()))
{
*strptr = str;
linecount++;
*strptr++;
}
if(inFile.eof())break;
}
}
inFile.close();//close file
}//processFile_strings[/B]Does anyone know what is happening? Could it be because theres unknown characters inputed from the file, that i should remove? If so what could they be?
