The **`getc` function** in C reads the next character from any input stream and returns an integer value. It is a standard function in C and can be used by including the `<stdio.h>` header file.

# Prototype
```c
int getc(FILE *stream)
```

# Parameter and return value



## Parameter:
- `stream`: A *file stream* or *standard input stream* identified by a pointer to the FILE object.
## Return value:
- `int`: Integer casting of the character read by `getc`. If the read operation is unsuccessful due to an error or the end of a file is reached, `EOF` is returned.

# Code



#include <stdio.h>

int main() {
  char c;

  printf("Enter a character: ");
  c = getc(stdin);
  printf("\nCharacter is: %c", c); // prints the character on standard output, /n is used to add a newline

  return 0;
}

In the code example above, the user is prompted for a character from standard input, and the value entered is read by the `getc` function. The value read is then stored in the `c` variable and displayed.

#include <stdio.h>

int main() {
  FILE *fp = fopen("sample.txt","r"); //file pointer opens the file in read mode
  printf("Character read from file is: %c", getc(fp)); //file content is: educative
  return 0;
}

In the example above, the `sample.txt` file is opened in read mode. The position pointed to by the file pointer (`fp`) is retrieved through `getc` and displayed.
