convert int to char...

How is this done, like in VB its CStr(thisInt). Its easy for int to float, etc., i know, but how can I convert an integer to a char?

Use the _itoa function.

Code:

---

//Example
#include <stdlib.h>
#include <stdio.h>

void main( void )
{
  char buffer[20];
  int  i = 3445;
  long l = -344115L;
  unsigned long ul = 1234567890UL;

  _itoa( i, buffer, 10 );
  printf( "String of integer %d (radix 10): %s\n", i, buffer );
  _itoa( i, buffer, 16 );
  printf( "String of integer %d (radix 16): 0x%s\n", i, buffer );
  _itoa( i, buffer, 2  );
  printf( "String of integer %d (radix 2): %s\n", i, buffer );

  _ltoa( l, buffer, 16 );
  printf( "String of long int %ld (radix 16): 0x%s\n", l,
                                                    buffer );

  _ultoa( ul, buffer, 16 );
  printf( "String of unsigned long %lu (radix 16): 0x%s\n", ul,
                                                    buffer );
}

_itoa, _i64toa, _ui64toa, _itow, _i64tow, _ui64tow
Convert an integer to a string.

char *_itoa( int value, char *string, int radix );

char *_i64toa( __int64 value, char *string, int radix );

char * _ui64toa( unsigned _int64 value, char *string, int radix );

wchar_t * _itow( int value, wchar_t *string, int radix );

wchar_t * _i64tow( __int64 value, wchar_t *string, int radix );

wchar_t * _ui64tow( unsigned __int64 value, wchar_t *string, int radix );

Return Value

Each of these functions returns a pointer to string. There is no error return.

Parameters

value

Number to be converted

string

String result

radix

Base of value; must be in the range 2 – 36

Remarks

The _itoa, _i64toa, and _ui64toa function convert the digits of the given value argument to a null-terminated character string and stores the result (up to 33 bytes) in string. If radix equals 10 and value is negative, the first character of the stored string is the minus sign ( – ). _itow, _i64tow, and _ui64tow are wide-character versions of _itoa, _i64toa, and _ui64toa respectively.

Thats a REALLY complicated way of doing something REALLY simple.

Code:

---

char a;
int b;
 
b = 65;
a = char(b);

---

That is not what he meant:

Code:

---

//if you try your code like this it will not work
int b = 65;
MessageBox(NULL,char(b),"OK",MB_OK);

---

You have to do it like this:

Code:

---

int b = 65;
char txt[2];
MessageBox(NULL,itoa(b,txt,10),"OK",MB_OK);

---

you were correct in what I was looking for Vlatko, but what is the difference between the two methods, for my own reference...

Vlatko used the correct function (itoa), whereas Zaei's method does not convert.

right, but what's the difference between Vlatko's, which works, and Zaei's, which doesn't work?? I guess what I'm saying is...what does Zaei's code do??

It turns 65 into 'A', rather than "65".

oh, okay, I get ya...thanks again Dennis...
