getc() is an example of a function available in stdio.h. For example, you may use printf() to output character string to the terminal (standard output). To write to file you may use fprintf(). To read a line from terminal or file you may use fgets() etc.
Basically, use either the <stdio.h> set of functions (C/C++) or the iostream objects (C++). Mix-n-match them in a single program isn't a good practice. I prefer stdio.h functions myself, but if you write C++ you do have a choice.
There are other stdio functions you may use also. I think any good C programming books or online tutorials should give you a good introduction to these functions.

fgets
FGETC(3) Linux Programmer's Manual FGETC(3)
NAME
fgetc, fgets, getc, getchar, ungetc - input of characters and strings
SYNOPSIS
#include <stdio.h>
int fgetc(FILE *stream);
char *fgets(char *s, int size, FILE *stream);
int getc(FILE *stream);
int getchar(void);
int ungetc(int c, FILE *stream);
DESCRIPTION
fgetc() reads the next character from stream and returns it as an unsigned char cast to an int, or EOF on end of file or error.
getc() is equivalent to fgetc() except that it may be implemented as a macro which evaluates stream more than once.
getchar() is equivalent to getc(stdin).
fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an
EOF or a newline. If a newline is read, it is stored into the buffer. A terminating null byte ('
