changing a set of char to string

[nameJack]

if i type in "twelve" on a cin syntax, can c++ change the twelve into number eg : t-116, w-119 and vice versa
i tried using
char letter[] = "twelve";
and the output is twelve
but i want it as integer. maybe the sum of all the ascii characters
can anyone help me?

you'd need to make a list of all the number words that are legal and then search the array for the word typed in and return the appropriate number.

int NumWordToInt(char* szNumWord)  // requires string.h and stdlib.h
{
  const static char nums[10][] = {"zero", "one", "two", "three", "four",
        "five", "six", "seven", "eight", "nine" };
  int i;
  char* pc;
  char temp[100]:
  // convert word to lower case
  for(pc = szNumWord; *pc; pc++)
     *(temp + (pc - szNumWord)) = tolower(*pc);
  *(temp + (pc - szNumWord)) = '\0';

  // search for the string
  for(i = 0; i < 10; i++)
  {
    if(strcmp(nums[i], temp) == 0) return i; // found a match
  }
  return -1; // error return
}

You can always make the function more sophisticated, but you get the idea.
