convert a string to a char array c++ code example

Example 1: string to char array c++

    string s = "geeksforgeeks"; 
  
    int n = s.length(); 
  
    // declaring character array 
    char char_array[n + 1]; 
  
    // copying the contents of the 
    // string to char array 
    strcpy(char_array, s.c_str()); 
  
    for (int i = 0; i < n; i++) 
        cout << char_array[i]; 
  
    return 0; 
}

Example 3: c++ string to char array
