C ++ int to string (integer to string)

1. Int sprintf (char * buffer, const char * Format [, argument]...);
<Stdio. h>
For example:
Int SS;
Char temp [64];
String STR;
Ss = 1000;
Sprintf (temp, "% d", SS );
String S (temp );
// Call the string method
Cout <S. c_str () <Endl; // 1000
Cout <S. Size () <Endl; // The length is 4

2. char * _ ITOA (INT value, char * string, int Radix );
<Stdlib. h>
For example:
Char buffer [20];
Int I = 3445;
_ ITOA (I, buffer, 10 );
String S (buffer );

3. stringstream ()
<Sstream. h>
For example:
Int Hello = 4;
Stringstream SS;
SS String S = ss. STR ();
// Call the string method
Cout <S. c_str () <Endl;
