C++ strcpy error [duplicate]




There is an array of structures:

struct schoolboy
  char firstName [30];
  char secondName [30];
  char addres [50];
  int schoolNumber;
  int schoolclass;
  schoolboy input (schoolboy * base);
  schoolboy recording (schoolboy * base, schoolboy * record, int number);

Here’s the implementation:

int main () {
  int number;
  setlocale (LC_ALL, "Rus");
  cout & lt; & lt; "Enter a number" & lt; & lt; endl;
  cin & gt; & gt; number;
  schoolboy base [28], record [28], a;
  a.input (base);
  a.recording (base, record, number);
  recordOut (record);
  system ("pause");
  return 0;

And here is the problematic function, the problem is in strcpy :

schoolboy schoolboy :: recording (schoolboy * base, schoolboy * record, int
if (base- & gt; schoolNumber == number)
  if (base- & gt; schoolclass == 10 || base- & gt; schoolclass == 11)
  cout & lt; & lt; "1" & lt; & lt; endl;
  for (int i = 0; i & lt; 2; i ++)
    strcpy (record [i] .firstName, base [i] .firstName); // error here
    strcpy (record [i] .secondName, base [i] .secondName);
    strcpy (record [i] .addres, base [i] .addres);
    cout & lt; & lt; "Haven't 10 or 11 class" & lt; & lt; endl;
    return * base;
  cout & lt; & lt; "Not found" & lt; & lt; endl;
  return * base;
 return * record;

How to fix the error? And could you give some advice on how to implement functions from structures in the “main”.


error C4996: 'strcpy': This function or variable may be unsafe.
Consider using strcpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS.

Answer 1, authority 100%

Replace all strcpy with strcpy_s.

Answer 2

If you don’t want to deal with studio troubles, there is another way. In the project settings, specify this as a predefined macro:


Or you can add this to the top of the file.
