Question

Could anyone tell me how to easily convert each character in a string to ASCII value so that I can sum the values?
I need to sum the values for a hash function.

Answer 1

Each character in a string is already ascii:

#include <string>
int main() {
  int sum = 0;
  std::string str = "aaabbb";
  for (unsigned int i = 0; i < str.size(); i++) {
    sum += str[i];
  }
  return 0;
}
