Re: How to tally an individual letter from input text

use a map container...

Something like this:

struct SLetter
{
int iUpperCount;
int iLowerCount;
};

struct SAlphabet
{
SLetter m_Letters[26];
};

SAlphabet alphabet = {0};

char text[1024];
for (int i=0;i<length;i++)
{
int iIndex = 0;

int bLower = islower( text[i] );
if(bLower)
{
iIndex = text[i] -'a' ;// give the zero based index of the letter
alphabet.m_Letters[iIndex].iLowerCount ++;
}
else
{
iIndex = text[i] -'A' ; // give the zero based index of the letter
alphabet.m_Letters[iIndex].iUpperCount ++;
}
}

a map does this...
each letter is referenced once, and there is only the existing letters into it... (if there is no 't' in the text for example, why allocating space for it ?). better, if you don't use the same alphabet as our ??? will your 26-values array be efficient ?
more, a map associate to each letter (the keys), a value, which is here the ratios...

just define a map<char, int>

It was intended as an alternative, i never said its the best solution Wink | ;)

Thanks tp both coaches. Those two topics are new to me. I will read into structures and mapping. Will ask you guys more later.

Check ShowScrollBar( UINT nBar, BOOL bShow = TRUE );
nBar one of SB_BOTH, SB_HORZ and SB_VERT.

you must write template<typename T> ... (but might have done this).

could you give us the line 1794 which is repporting the compile error please ?

the Brackets <typename T> has been suppressed by posting the message.

unfortunately there is no file : msc1.cpp to be found!

Thats why I am asking Smile | :)

sounds silly but have you tried "Rebuild ALL"

i can't even remember what my point is now, but anyway, i'm correct

There's another coding style for function templates by putting the return type of function template into a new line as:

template <class T><br />
<font color:red>void</font> FooBar(T& aa, T& bb)<br />
{<br />
<font color:red>return</font> aa - bb;<br />
}

don't put either into "". even if the compiler does find it, prefer the standard notation for system includes, like <stdio.h>.
also, if you are coding in pure C++, you can use <cstdio>. that will have the consequence to put all standard functions into the std:: namespace.

Converting short to array of bytes

msc1.cpp is a red herring: that's information for Microsoft support (it's the compiler's source file).

Visual C++ 6.0 didn't support member function templates very well, if at all. If you must do this, use Visual Studio .NET 2003. The C++ compiler toolset from VS.NET 2003 is available as the Visual C++ Toolkit 2003[^].

I was going to point out the many errors in this code, but I'm actually not going to, because I suspect it's an academic exercise.

Stability. What an interesting concept. -- Chris Maunder

Xtreme method here (with VC++ 7.0):

#include <iostream>

struct Foo
{
char Byte[0];
};

void main()
{
const int iSize = 5;
short nNum[iSize] = {1, 2, 3, 4, 5};
Foo* p = reinterpret_cast<Foo*>(nNum);
for(int i = 0; i < (iSize * 2); i++) {
int iTmp = p->Byte[i];
printf("%d ", iTmp);
}
}
