fgetc() function in C

Prototype:

    int fgetc(FILE *filename);

Parameters:

    FILE *filename

Return type: int

Use of function:

In the file handling, through the fgetc() function we take the next character from the input stream and increments the file pointer by one. The prototype of the function fgetc() is: int fgetc(FILE* filename);

It returns an integer value which is conversion of an unsigned char. It also returns EOF which also in turns an integer value.

fgetc() 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
		fputc(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("File content is--\n");
	printf("\n...............print the strings..............\n\n");
	while(!feof(f)){
		//takes the characters in the character array 
		ch=fgetc(f);						
		//and print the characters
		printf("%c\n",ch);
	}

	fclose(f);

	return 0;
}
