How to Write a C-language program for Addition,Substraction,Multiplication and Division.

1)-Write a C- program for addition of n number .#java 8 download.

program for addition

output of addition

#include<stdio.h>

#include<conio.h>

Void main()

{

Int  a,n,i,sum=0,;

Clrscr();

Printf(“Enter the  number which you want to add  \n”);

Scanf (“%d”,&n);

Printf(“Enter the numbers   \n” );

For(i=1; i<=n; i++)

{

Scanf(“%d”,&a);

Sum=sum+a;

}

Printf(“After  addition result=%d”,sum);

getch();

} 

Input:-Enter the  number which you want to add 

                    4

Enter the numbers

1

2

3

4

 output  :- After  addition result=     10

Program in c language using if-else condition.

2)- Write a C-language program for the Substraction of two numbers.

#include<stdio.h>

#include<conio.h>

Void main()

{

Int  a,b, Sub;

Clrscr();

Printf(“  Enter the number from which you want to substract  \n”);

Scanf(“%d”,&a);

Printf(“Enter the number  which you want to substract  \n”);

Scanf(“%d”,&b);

Sub=a-b;

Printf(“After Substraction  result=%d”,Sub);

getch();

}

Input:-Enter the number from which you want to substract

                65

Enter the number  which you want to substract  

                 4

output  :-After Substraction  result=61

program for substraction

output

3)- Write a C- program for Multiplication of n number.

#include<stdio.h>

#include<conio.h>

Void main()

{

Int  a,n,i, Multi=1,;

Clrscr();

Printf(“Enter the  number which you want to multiply  \n”);

Scanf (“%d”,&n);

Printf(“Enter the numbers   \n” );

 For(i=1; i<=n; i++)

{

Scanf(“%d”,&a);

               Multi =Multi * a;

}

Printf(“After  Multiplication  result=%d”,Multi);

getch();

}

Input:-Enter the  number which you want to multiply

                 4

Enter the numbers

1

2

3

5

output  :-After  Multiplication  result=30

program for multiplication

               

output

 4)- Write a C-language program for the division of two numbers.

#include<stdio.h>

#include<conio.h>

Void main()

{

float  a,b, Div;

Clrscr();

Printf(“Enter the number  which you want to divide \n”);

Scanf(“%f”,&a);

Printf(“Enter the number from which you want to divide  \n”);

Scanf(“%f”,&b);

Div=a/b;

Printf(“After division Result=%f”,Div);

getch();

}

Input:-Enter the number  which you want to divide

                 20

Enter the number from which you want to divide

                4

output  :-After division Result=  5.00000

program for division

Div output
