What are the commonly used input output functions in C?

Answer 1

Commonly used input/out functions in C are:

* printf( )

* scanf( )

scanf() it is the standard input functions. It is used to get the data from the input devices, which is by default a keyboard, at run time, or execution time. Its general format is:

scanf("one or more format specifier",& one or more variables separated by comma);

For example:

scanf("%d",&a);

scanf("%d%,&a,&b);

printf() It is the standard output functions it is used to show the data to an output device, which is by default a monitor screen, at run time, or execution time. Its general format is:

for example:

scanf("%d",&a);

scanf("%d%f",&a,&b);

Answer 2

Functions are :

getchar(), putchar(), scanf(), printf(), gets() & puts()

functions can be accessed within a program by including the header file stdio.h.

Answer 3

Virtually every function is an input output function. Functions that return a value are output functions and those that accept arguments are input functions. Non-constant arguments passed by reference can also be used for output. The only functions that are neither input or output functions are void functions that accept no arguments. These are really nothing more than procedures

Answer 4

Scanf("%type_of_input",&variable_name);

where type of input can be Integer and it's symbol will be %d

or Float and it's symbol is %f

or double %lf

printf("Hello World");

to print a message on the screen,

also you can use this code to print a stored value in a variable.

printf("Hello World number %variable_type",variable_name);
