std::String = "aBx";
String.toupper();

or

String.ToUpper();

it was something like this.

[Danny Kalev]

apply toupper() to each char in the string.

This is for C program.

if you have character strings 'A','B','C',....'Z' and 'a','b','c',....'z'


the ASCII code for them are:-

'A' = 65 'a' = 97
'B' = 66 'b' = 98
. .
. .
. .
'Z' = 90 'z' = 122


the diffrence beteeen lowercase 'a' and upercase 'A' is delta

delta = 97 - 65 = 32

to conver from low to upp case:-

char x='a';

printf(" x= %d \n",x);

printf(" x= %d \n",x-32);

printf(" x= %c \n",x-32);

output is:-

x = 97
x = 65
x = 'A'

Hi,

if you are using VC++ there is a cool solution for this problem.

//...
CString csUpper; // it will contain the string as uppercase
char* cs = "it in uppercase"; // text

csUpper = cs; // CString object now has your string
csUpper.MakeUpper(); // turning it as uppercase
printf("%s\n",csUpper); // showing it on the screen
//...

Note : Your project must support MFC

_strupr()

* Note: It will not work with a literal constant string without a strdup(),
use only with buffers.

The answer to that is not as easy as you might guess. The first thing
we need to know is exactly what do you mean by "a string"?

A C++ std::string?
An MFC CString?
A C string (NUL terminated array of characters)?

After we decided that, then we need to know is we're deal with just
English, or do we have to consider other languages as well?

For each of those, the answer is quite different.

I found a nice case-insensitive strcmp somewhere, but I can`t remember where.
It was just some source code to put in your string.h file.

There is no standard one, but most compilers offer one as an extension.
However, they can't agree on a name. Some use stricmp(), other use
strcmpi(), and still others use istrcmp().

And leave us not forget... _tcsicmp(), _mbsicmp(), and _wcsicmp(). <g>
