Use itoa() on the integer.
If you are using std::strings, then just add the result of the itoa to the string.

If char[], create a new char[] and itoa() the integer and store in the new array. Measure the length of the new array, and create a third the size of the first 2 + 1.
Copy the 2 chars into the new array, and add'\0'

Try out a good ole C solution:

char buff[256] = "Time remaining: ";

char cat[256];

sprintf(cat, "%d", 101);

strcat(buff, cat);

printf(buff);

{
strstream s;
s << str << 1 << ends;
str = s.str();
}

if you use MFC, you can do like follow:

CString szResult = &quot;&quot;;
TCHAR szChar[100] = &quot;How are you &quot;;
int nSize = 100;

szResult.Format(&quot;%s%d&quot;,szChar,nSize);

do it,you can sucess
