#include <iostream>
#include <cstring>
int main()
  const char *str = "Try not. Do, or do not. There is no try.";
  char target = 'T';
  const char *result = str;
  while ((result = std::strchr(result, target)) != NULL) {
    std::cout << "Found '" << target
              << "' starting at '" << result << "'\n";
    // Increment result, otherwise we'll find target at the same location


Found 'T' starting at 'Try not. Do, or do not. There is no try.'
