Two other I/O functions getchar() and
putchar() to receive input from keyboard and provide output to the screen of a
character respectively are provided. gets() and puts() functions are used to
receive input and provide output of strings respectively. get() function
receives a character input and provides eof() when end of file is encountered.
getline() function is similar to the get() function. However, get() function
leaves the terminating character in the stream and getline removes the
terminating character. read() and write() member functions are used to receive
input from the keyboard and provide output to the screen of multiple characters
respectively. gcount() is the function to count the number of characters
received in input.
Arrays
Arrays are structures of multiple
variables of same data type. Arrays can be one dimensional of multi
dimensional. Strings are multiple characters in an array having an extra NULL
character (\0) at its end. So, total number of characters in a string are
always one more than its length. As an array is a group of variables, each
variable of an array is called an element. Syntax to define an array is :
data_type name[length]; syntax to define multi/two-dimensional array is :
data_type name[number of rows][number of coloumns].
