The C language comes with standard functions printf() and scanf() so that a programmer can perform formatted output and input in a program. The formatted functions basically present or accept the available data (input) in a specific format.
C provides standard functions scanf() and printf(), to perform formatted inputs and outputs. These functions accept a format specification string and a variable list as the parameters.
The function printf() is used for formatted output to standard output based on a format specification. The format specification string, along with the data to be output, are the parameters to the printf() function. Syntax: printf (format, data1, data2,……..);
Unformatted input/output functions
Unformatted console input/output functions are used to read a single input from the user at console and it also allows us to display the value in the output to the user at the console. Reads a single character from the user at the console, without echoing it.
Formatted I/O -- refers to the conversion of data to and from a stream of characters, for printing (or reading) in plain text format. All text I/O we do is considered formatted I/O.
Formatted I/O functions are used for storing data more user friendly. Unformatted I/O functions are used for storing data more compactly. Formatted I/O functions are used with all data types. Unformatted I/O functions are used mainly for character and string data types.
In C, sscanf() is used to read formatted data. It works much like scanf() but the data will be read from a string instead of the console.
Unformatted text contains only the words; it has no information on fonts, indents, spacing, autonumbering, and so on. Formatted text contains these types of information.
The printf() function sends a formatted string to the standard output (the display). This string can display formatted variables and special control characters, such as new lines ('\n'), backspaces ('\b') and tabspaces ('\t'); these are listed in Table 2.1.
Types of Data Types in C
Floating-point, integer, double, character. Union, structure, array, etc. The basic data types are also known as the primary data types in C programming.
There are several ways to format output. To use formatted string literals, begin a string with f or F before the opening quotation mark or triple quotation mark. User can do all the string handling by using string slicing and concatenation operations to create any layout that user wants.
In C, the fprintf() function is used to print formatted data to a file.
String provides format() method can be used to print formatted output in java. System. out. printf() method can be used to print formatted output in java.
An input format describes how to interpret the contents of an input field as a number or a string.
The %s means, "insert the first argument, a string, right here." The %d indicates that the second argument (an integer) should be placed there. There are different %-codes for different variable types, as well as options to limit the length of the variables and whatnot. Control Character.
There are mostly six types of format specifiers that are available in C.
Formatted input/output functions
Formatted console input/output functions are used to take one or more inputs from the user at console and it also allows us to display one or multiple values in the output to the user at the console. This function is used to read one or multiple inputs from the user at the console.
A scanf format string (scan formatted) is a control parameter used in various functions to specify the layout of an input string. The functions can then divide the string and translate into values of appropriate data types. String scanning functions are often supplied in standard libraries.
Text formatting data may be qualitative (e.g., font family), or quantitative (e.g., font size, or color). It may also indicate a style of emphasis (e.g., boldface, or italics), or a style of notation (e.g., strikethrough, or superscript).
In computing, formatted text, styled text, or rich text, as opposed to plain text, is digital text which has styling information beyond the minimum of semantic elements: colours, styles (boldface, italic), sizes, and special features in HTML (such as hyperlinks).
Formatted text can draw the reader's attention to specific parts of a document and emphasize important information. In Word, you have several options for adjusting text, including font, size, and color. You can also adjust the alignment of the text to change how it is displayed on the page.
"%10d" means to pad with spaces on the left, as needed, so decimal output is at least 10 characters.
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.
There are 5 different types of errors in C programming language: Syntax error, Runtime error, Logical error, Semantic error, and Linker error.
