strlen in C++

#include <cstring>
#include <iostream>
using namespace std;

int main() {
  char str1[] = "This a string";
  char str2[] = "This is another string";

  // find lengths of str1 and str2
  // size_t return value converted to int    
  int len1 = strlen(str1);
  int len2 = strlen(str2);

  cout << "Length of str1 = " << len1 << endl;
  cout << "Length of str2 = " << len2 << endl;

  if (len1 > len2)
    cout << "str1 is longer than str2";
  else if (len1 < len2)
    cout << "str2 is longer than str1";
  else
    cout << "str1 and str2 are of equal length";

  return 0;
}
