What Is The Return Type Of Getchar(), Fgetc() And Getc() ?
In C, when you use getchar(), fgetc(), or getc(), what you get back is not a character but an integer. So, it’s a good idea to catch that integer by using an integer-type variable. These functions return the ASCII value of the character you input or read, and using an integer-type variable helps you handle and check for special cases like the end of the file.
char ch; /* May cause problems */
while ((ch = getchar()) != EOF)
{
putchar(ch);
} This version uses integer to compare the value of getchar().
int in;
while ((in = getchar()) != EOF)
{
putchar(in);
} FAQ- What Is The Return Type Of Getchar(), Fgetc() And Getc() ?
Q1. What is the return type of Getchar ()?
Ans. The getchar() function obtains a character from stdin. It returns the character that was read in the form of an integer or EOF if an error occurs
Q2. What is getc () and Getchar () in C?
Ans. In C, there are two ways to read characters: getc() and getchar(). The key difference is that getc() can read from anywhere, not just the usual input. But, if you’re just grabbing a character from the regular input, using getchar() is like taking a quick and easy route – it’s the same as saying getc(stdin). So, if you’re sticking to the standard input, getchar() is the simpler choice.
Q3. What is the difference between fgetc and getc?
Ans.
In C, there are two buddies, fgetc() and getc(), doing the same job of getting characters. But here’s the thing: fgetc() is a real subroutine, not just a fancy term like “macro” used for getc(). However, there’s a trade-off – fgetc() might be a bit slower than getc(), but it’s more efficient in terms of using less disk space. So, depending on your needs, you might choose one over the other.
