An application can call WSAStartup more than once if it needs to obtain the WSADATA structure information more than once. On each such call, the application can specify any version number supported by the Winsock DLL.

#include <stdio.h>

int index(char[], char[]);

int main()
{
  char* str = "foo bar baz";
  char* str2 = "barz";
  
  if(index(str, str2) != -1)
    printf("found");
  else
    printf("not found");
  return 0;
}

int index(char s[], char t[])
{
  int i, j, k;
  for (i = 0; s[i] != '\0'; i++)
  {
    for (j = i, k = 0; t[k] != '\0' && s[k] == t[k]; j++, k++)
      ;
    if(t[k] == '\0')
      return i;
  }
  return -1;
}

string s = R"(!@#$%^&*()'")";

for(char c : s) cout << c << " ";

cout << "\n";

for(int i = 0; i < s.size(); ++i)
    cout << s[i] << " ";

cout << "\n";

const char* symbols = s.c_str();
for(int i = 0; i < s.size(); ++i)
    cout << symbols[i] << " ";

И есть ли регулярные выражения в С++?
