How can you convert int type to const char*
ajh32 (659)
_itoa_s(int, char*, size_t, int)

argv[0] - input integer
argv[1] - char array for output
argv[2] - size of the array at argv[1]
argv[3] - radix, i.e. number base

int a(12345);
char arr[6] = {0};
_itoa_s(a, &arr, sizeof(arr), 10);  // using base 10

    const char * text = "Some words.";
    cout << text << endl;

    int x = reinterpret_cast<int>(text);
    cout << "x = " << showbase << hex << x 
         << " or " << dec << x << endl;
    
    const char * ptr = reinterpret_cast<const char *>(x);
    cout << ptr << endl;
 
Some words.
x = 0x466064 or 4612196
Some words.
