C programming language: C program to divide a number (mathematics operation).

// Normal program
#include<stdio.h>
#include<conio.h>
void main()
{
int a=40,b=2;
printf("Result: =%d",a/b);
getch();
}

output:-20

//Ask numbers from user to divide
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b;
float c;
printf("\n Enter Number: ");
scanf("%d %d",&a,&b);
c=a/b;
printf("Result: =%f",c);
getch();
}

C progamming language: C program to Multiply to numbers (Mathematics operation).

//Normal program

#include<stdio.h>

#include<conio.h>

void main()

{

int a=20,b=10;

printf("%d",a*b);

getch();

}

outout:200

//Ask numbers from user to Multiply

#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c;
printf("Enter No to multiply: ");
scanf("%d %d",&a,&b);
c=a*b;
printf("Multiplication Result= %d",c);
getch();
}

C programming language: C program to subtract two numbers (Mathematics operation).

//Normal program
#include<stdio.h>

#include<conio.h>

void main()

{

int a=20,b=10;

printf("%d",a-b);

getch();

}

output:- 10

//Ask number from user to Subtract

#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c;
printf("Enter No to subtract: ");
scanf("%d %d",&a,&b);
c=a-b;
printf("Subtraction= %d",c);
getch();
}

C progarmming language: C program to add two numbers (Mathematics operation).

//Normal program
#include<stdio.h>

#include<conio.h>

void main()

{

int a=10,b=30;

printf("%d",a+b);

getch();

}

output:- 40

//Ask number from user to add

#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c=0;
printf("Enter No to add: ");
scanf("%d %d",&a,&b);
c=a+b;
printf("%d + %d= %d",a,b,c);
getch();
}

C progammimg langauge: What is software and types of software?

A Software can be defined at two standards:-

        1.As per industrial standard,

      2.As per programmer standard.

 1.As per industrial standard:-

           #  As per the industrial standard digitized automated process is called software.

              Digitized =>Provides GUI.

          #when the software is providing GUI then it is called digitized, without human interaction the process is completed then it is called automated system.

 2.As per programmer standard:-

# A software is collection of programs.

# A program is a set of instructions which is design for particular task.

# N numbers of program combining together like a single unit it is called software tool or s/w component.

Advantages of software:

Generally software provides so many advantages but among of those following three are very important:-

            a. Performance

            b. Security and

            c. Any time access.

Software classified into two types:-

    1. System software.

    2. Application software.

1.System software:-

    When we are developing a software for general purpose which doesn’t having any limitations it is called system s/w.

System s/w are classified into three types:

         a. Operating system:

                     Example: DOS, WINDOWS, UNIX, LINUX.

         b.Translator

                     Example: COMPILER, INTERPRETER.

         c. Packages

                    Example: LINKER, LOADER, EDITOR.

 2.Application software:-

       When we are developing an s/w for specific task only then it  is called application s/w.

       Always application s/w having limited task only i.e. for one  purpose we developed same purpose we required to use.

       Client specific projects all are application s/w only.

Application s/w are classified into two types:

    a. Application packages

         Example: MS office, ORACLE.

MS office is a Microsoft product which maintain the information in the form of documents, And

ORACLE is a database which maintain the information in the form of table.

    b. Special purpose software.

                Example: TALLY.

By using tally we can maintain accounts related information.

C progamming language: My first c program

#include<stdio.h>

#include<conio.h>

void main()

{

printf("IT IS MY FIRST C PROGRAM ");

getch();

}

output: IT IS MY FIRST C PROGRAM
