Converting int to string
-
I have two questions. The first one is regarding the conversion from int to string. I can successfully convert a numeric string to int with the follwing code (particularly useful if you need to make mathematical operations on the numeric values contained in a string): string VALUE_AS_STRING = "1234"; int VALUE_AS_INT = atof (VALUE_AS_STRING.c_str()); cout << "The numeric value of the string is: " << VALUE_AS_INT; ...but I am not able to do the opposite, eg convert an int into a string. Any help please? Second question : How come the condition below results in an error? How should it rather be written? char CHARACTER = "1"; if (CHARACTER == "1") {cout << "True";} Many thanks

Should use
atoi().J_E_D_I wrote:

Use single quote.
if(character == 'a') {
cout << "It is a";

Another method in addition to Maxwell's sprintf()...
#include <sstream>
...
int SomeInt = 5;std::ostringstream NumericStringStream;
NumericStringStream << SomeInt;
std::string NumericString = NumericStringStream.str();

For Question One :- would wsprintf or CString::format is of any use!

use ' instead of "
