getc() function in C

Prototype:

    int getc(FILE *filename);

Parameters:

    FILE *filename

Return type: int

Use of function:

In the file handling, through the getc() function we take the next character from the input file stream and increment the file position pointer. The prototype of the function getc() is:

    int getc(FILE *filename);

It returns an integer value which is conversion of an unsigned char. It also returns EOF which itself is also an integer value. Whenever there is a binary file, check for EOF with the function feof().

getc() example in C

#include <stdio.h>
#include <stdlib.h>

int main(){
	//Initialize the file pointer
	FILE *f;
	char ch;
	//Create the file for write operation
	f=fopen("includehelp.txt","w");
	printf("Enter five character\n");
	for(int i=0;i<5;i++){
		//take the characters from the users
		scanf("%c",&ch);
		//write back to the file
		putc(ch,f);
		//clear the stdin stream buffer
		fflush(stdin);
	}
	//close the file after write operation is over
	fclose(f);
	//open a file
	f=fopen("includehelp.txt","r");
	printf("Write operation is over and file is ready for read operation\n");
	printf("\n...............print the characters..............\n\n");
	while(!feof(f)){
		//takes the characters in the character array 
		ch=getc(f);
		//and print the characters
		printf("%c\n",ch);
	}
	fclose(f);
	
	return 0;
}
