In case you have MFC Application you can use .

Using STL string

#include <string>
char szAppPath[MAX_PATH] = "";
std::string strAppName;
::GetModuleFileName(0, szAppPath, MAX_PATH);
// Extract name
strAppName = szAppPath;
strAppName = strAppName.substr(strAppName.rfind("\\") + 1);
CString str =strAppName.c_str();
MessageBox(str);

Using CString (MFC)

MessageBox(strAppName);

• 'char*' -> this is also called a C-style string, or an ANSI string.
• 'wchar_t*' -> this is wide character string, i.e. an 'unsigned short*'
• 'CString' -> this is a string wrapper class, which is part of the Microsoft Foundation Classes (MFC).
• 'std::string' -> this is a Standard C++ Class wrapping a char string. It is part of the Standard Template Library, or STL.
• 'std::wstring' -> this is a Standard C++ Class wrapping a wchar_t string. It is part of the Standard Template Library, or STL.
• 'BSTR' -> this known as basic string or binary string, and is a pointer to a wide character string used by Automation data manipulation functions.

First Method

char c[10];
int i = 1234;
sprintf(c, "%d", i);
