The EOF is a special
character, whose ASCII value is 26, which indicates the end of a file in text
mode of file. While writing data to a file, this character is inserted
automatically after the last character in the file to mark the end of file. If
this character is detected at any point in the file, the read function would
return the EOF signal to the program indicating the last point of file. An
attempt to read after EOF might either cause the program to terminate with an
error or result in an infinite loop situation. Thus, the last point of file is
detected using EOF while reading data from file. Without this mark, we can not
detect last character at the file such that it is difficult to find up to what
time the character is to be read while reading data from the file.
Like any other variables, we can also pass entire array to a function. An array name can be named as an argument for the prototype declaration and in function header. When we call the function no need to subscript or square brackets. When we pass array that pass as a call by reference because the array name is address for that array. /* Program to illustrate passing array to function */ #include<stdio.h> void display(int) ; /* function prototype */ main( ) { int num[5] = {100, 20, 40, 15, 33, i ; clrscr( ) ; printf (“\n The content of array is \n”) ; for (i=0; i<5; i++) display (num[i]) ; /*Pass array element fo fun */ getch{ } ; } void display(int n) { printf (“\t%d”, n ) ; } Output: The content of array is 100 20 40 15 3 /* Program to read 10 numbers from keyboard to store these num into array and then c...
