System Development Life Cycle(SDLC)

By
               All organizations have several types of information system. At any point in time, varying degree of these information systems may be computer based. For example, an organization's payroll information system may be computer based, but its strategics planning information system maybe processed manually. As time passes, organizational processes change. The organization's information system must change in response to the changing needs of the organization. When this occurs, management usually initiates some form of a system development life cycle(SDLC) to address the problem.

Difference between Binary mode and Text Mode in C programming

By
There are mainly three difference between binary and text mode. They are as follow.               i.       In text mode, a special character EOF whose ASCII value is 26 is inserted after the last character in the file to mark the end of file. But, there is no such special character present in the binary mode. The binary mode files keep track of the end of file from the number of characters present in the directory entry of the file.             ii.       In text mode of file, text and numbers are stored as one character per byte. For example, the number 1234 occupies two bytes in memory but it occupies 4 bytes (one byte per character) in the file. But, in binary mode, the number occupies the number of bytes as it occupies in the memory. Thus,  the above number occupies two bytes in file also in the case o...

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...

Types of Functions in C Programming

By
C program has two types of functions: 1. Library Functions 2. User defined functions Library Functions: These are the functions which are already written, compiled and placed in C Library and they are not required to be written by a programmer. The function’s name, its return type, their argument number and types have been already defined. We can use these functions as required. For example: printf(), scanf(), sqrt(), getch(), etc. User defined Functions: These are the functions which are defined by user at the time of writing a program. The user has choice to choose its name, return type, arguments and their types. The job of each user defined function is as defined by the user. A complex C program can be divided into a number of user defined functions. For example: #inlcude<stdio.h> double convert (int) ; /* function proto type */ main() { int c ; /* double d ; */ printf (“Enter temperature in Celsius: ”) ; scanf (“%d”, &c) ; /* d =...
