Numbers in string declaration

[gccntn]

Hello,

I need to embed an integer variable into a string declaration. I tried
the following, but it failed:
int myInt = 16;
string myText = "Value = " + string(myInt);
Can you help me with this?

On another note, I was wondering how I can output the value of an int
in base 16. For instance, how can I write the following in C++?
printf("Value = 0x%x\n",myInt);

Thanks in advance for your help.

For the first question, see:

For the second, use <iomanip> and std::hex, like this:

cout << "0x" << hex << myInt;

Cheers! --M

std::cout << "Value = 0x" << std::hex << myInt << '\n';

Look up the iostream manipulators for more information.
