C getc

C getc() function is a C library function, which reads a character from a file that has been opened in read mode by the fopen() function. This tutorial guides you on how to use the getc() function in the C program.

Syntax:

int getc( FILE * stream );

Return Value

• getc() function returns the next requested object from the stream on success.
• Character values are returned as an unsigned char cast to an int or EOF at the end of the file or error.
• The functions feof() and ferror() must be used to distinguish between end-of-file and error.

Example:

#include<stdio.h>

int main()
{
    FILE *fp = fopen("fileName.txt", "r");
    int ch = getc(fp);
    while (ch != EOF)
    {
        //To display the contents of the file on the screen
        putchar(ch);
        ch = getc(fp);
    }

    if (feof(fp))
        printf("\n Reached the end of file.");
    else
        printf("\n Something gone wrong.");
    fclose(fp);

    getchar();
    return 0;
