The C function fgets () is deprecated and discontinued in 2011.

gets() is risky to use!

I did a program update and used the fgets() function
instead of the gets() function.

char *gets(char *str)
https://www.tutorialspoint.com/c_standard_library/c_function_gets.htm

char *fgets(char *str, int n, FILE *stream)
https://www.tutorialspoint.com/c_standard_library/c_function_fgets.htm


Before each call of function fgets()
we must reserve memory for the string str[i].
