The humble small white online seek counsel-CodePudding

Simple c + + to open the file operations:
#include
Int main ()
{
The FILE * p;
P=fopen_s (" F: \ \ 1. TXT ", "w");

return 0;
}
Always prompt the following error: (with vs2019)
Const char * type of real participation of "FILE" * * type parameter is not compatible with
The parameters in the function call little
"Fopen_s:" function does not accept two parameters [/b]

Really don't know where is wrong, please teach a great god,

} 
The else {
Printf (" The file 'crt_fopen_s. C' was not The opened \ n ");
