| fgets ( ) | read a string from a file |
What is a function using input and output?
In mathematics, a function is any expression that produces exactly one answer for any given number that you give it. The input is the number you feed into the expression, and the output is what you get after the look-up work or calculations are finished.
What are input output functions in C?
The basic input/output functions are getchar , putchar , puts , scanf and printf . The first two functions, getchar and putchar, are used to transfer single characters.
What are input output statements in C?
C programming language provides a set of built-in functions to read given input and feed it to the program as per requirement. Output : In any programming language output means to display some data on screen, printer or in any file. C programming language provides a set of built-in functions to output required data.
When the input of the function is 1 What is the output of the function?
When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.
What is Input Output?
Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to “perform I/O” is to perform an input or output operation.
What are the input output functions available in C for binary files?
In binary files, each byte may not be a character. NOTE : Formatted input/output(printf,scanf) , character input/output(getchar, putchar), and string input/output(fgets, fputs) functions can be used only with text files.
What are formatted input and output functions in C?
Formatted input/output functions
| Functions | Description |
|---|---|
| scanf() | This function is used to read one or multiple inputs from the user at the console. |
| printf() | This function is used to display one or multiple values in the output to the user at the console. |

Can 2 inputs have the same output in a function?
Each input has only one output. Remember that in a function, the input value must have one and only one value for the output. Domain and Range. There is a name for the set of input values and another name for the set of output values for a function.
What are the Basic Input/Output Functions in C programming?
The basic input/output functions are getchar, putchar, puts, scanf and printf. The first two functions, getchar and putchar, are used to transfer single characters. The next function puts is used to output strings, and the last two functions, scanf and printf, permit the transfer of single characters, numerical values and strings.
How do you enter input input data in C?
Input data can be entered from a standard input device by means of the C library function scanf. This function can be used to enter any combination of numeric values, single characters and strings. The function returns the number of data items that have been entered successfully.
How to enter inputinput data from a standard input device?
Input data can be entered from a standard input device by means of the C library function scanf. This function can be used to enter any combination of numeric values, single characters and strings. The function returns the number of data items that have been entered successfully. In general terms, the scanf function is written as:
