What is difference between scanf and gets?

The main difference between them is: scanf() reads input until it encounters whitespace, newline or End Of File(EOF) whereas gets() reads input until it encounters newline or End Of File(EOF), gets() does not stop reading input when it encounters whitespace instead it takes whitespace as a string.

What is Getchar used for?

getchar is used to read data from the keyboard ( stdin). Effectivly it is a fgetc(stdin). The problem with this function is that the characters are buffered until RETURN is hit!

What is the difference between Gets and Getchar?

getch reads a single character directly from the keyboard, without echoing to the screen. This function return the character read from the keyboard. getch does not wait for the user respond after reading a character from console. getchar() is used to get or read the input (i.e a single character) at run time.

What is difference between Scanf and Sscanf?

scanf reads from the standard input stream stdin. fscanf reads from the named input stream. sscanf reads from the character string s. Each function reads characters, interprets them according to a format, and stores the results in its arguments.

Why puts is used in C?

The puts() function in C/C++ is used to write a line or string to the output( stdout ) stream. It prints the passed string with a newline and returns an integer value. The return value depends on the success of the writing procedure. ... int puts ( const char * str);

Why is Getchar better than Scanf?

scanf is a C function to read input from the standard input until encountering whitespace, newline or EOF while getchar is a C function to read a character only from the standard input stream(stdin), which is the keyboard. Thus, this is the main difference between scanf and getchar.

What is the purpose of Sprintf?

sprintf() function in C

sprintf() function is a file handling function in C programming language which is used to write formatted output to the string. Please find below the description and syntax for each above file handling functions. Declaration: int sprintf(char *string, const char *format, …)

What is the return type of getchar ()?

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.

Does Getchar read newline?

getchar() is equivalent to getc(stdin). gets() reads a line from stdin into the buffer pointed to by s until either a terminating newline or EOF, which it replaces with a null byte (aq\0aq). No check for buffer overrun is performed (see BUGS below).

What is getch () function?

getch() method pauses the Output Console untill a key is pressed. It does not use any buffer to store the input character. The entered character is immediately returned without waiting for the enter key. The entered character does not show up on the console.

What is scanf in C?

In C programming, scanf() is one of the commonly used function to take input from the user. The scanf() function reads formatted input from the standard input such as keyboards.

Why does Getchar return an int?

The getchar() function returns an integer which is the representation of the character entered. ... The reason it returns an int rather than a char is because it needs to be able to store any character plus the EOF indicator where the input stream is closed.
