End Of File (EOF) in Programming

By


               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.

Passing arrays to functions in C programming

By
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...

CPU (Central Processing Unit)

By
PGA reffered as pin grid array in which pins of CPU are lined up in a straight format. SPGA referred as staggered pin grid array. in which pins of CPU are arranged staggered format. LGA reffered to as Land Grid Array in which pins are available within inside the socket but not in the CPU in other words in line grid array, in CPU ther are no pinsbut insteadpins areattached with in a socket which contact with with the CPU. for e.g. LGA775 socket(no pins on cpu) has better cooling system. better contact and better locking(climbing). LGA1155: Letest generation I socket, also reffered as sandy bridge, Turbo boost overclocking. More resent than LGA 1156 socket. LGA1156: ability to north bridge Doul channel DDR3 optional integreted graphics PCI express LGA1366: hi end core i series socket integreted tiple channal memmory controller external control bridge(HUB) Upgrading CPU: need to check its core suppert check multiprocessor supports or not check on the ...

Recursive Function in C programming

By
             If a statement within the body of a function calls the same function, the function is called recursive function. Actually, recursion is a process by which a function calls itself repeatedly until some specified condition has been satisfied. This process is used for repetitive computations in which each action is stated in term of previous result. Many iterative or repetitive problems can be written in this form.                To solve a problem using recursive method, two conditions must be satisfied. They are: 1)       Problem could be written or defined in term of its previous result. 2)       Problem statement must include a stopping condition. /*   An example of recursive function to calculate factorial of a number.*/    #include<stdio.h>    #include<conio.h...
