Answer 1

If I understand you correctly, you simply need to convert the integer to a string first, and then concatenate the result to the first string.

strcat() and _itoa_s() should do the trick.

If your string type is std::string instead of char*, then you can code something like:

char buff[20];
std::string a ("The number is ");
int b = 2000;
_itoa_s (b, buff, sizeof (buff) / sizeof (char), 10);
a += buff;

Use CString's Format()

example.

int iFileCount = 1;

CString strFileName;
strFileName.Format("image%d.jpg",iFileCount);

//some operation

iFileCount++; // For next file name

Answer 5

Use CString's Format()

example.

int iFileCount = 1;

CString strFileName;
strFileName.Format("image%d.jpg",iFileCount);

The string literal should be decorated with _T() or TEXT(), so the code can be built in Unicode as well:

  strFileName.Format( _T("image%d.jpg"), iFileCount );
