Exercise 4

Write a C Program to print the multiplication table of a given number n up to a given value, where n is entered by the user.

SOURCE CODE:

/*Program to print the multiplication table of a given number.*/

#include<stdio.h>

#include<conio.h>

void main()

{

 int n,m,i;

 clrscr();

 printf("\nEnter number:");

 scanf("%d",&m);

 printf("\nEnter range:");

 scanf("%d",&n);

 for(i=1;i<=n;i++)

  printf("\n%d * %d = %d",m,i,m*i);

}

OUTPUT:

Write a C Program to enter a decimal number, and calculate and display the binary equivalent of that number.

SOURCE CODE:

/*Program to display binary equivalent of the given decimal number.*/

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

 long int revbn=0,bn=0,dn,c=0;

 clrscr();

 printf("\nEnter decimal number:");

 scanf("%ld",&dn);

 while(dn>0)

 {

  revbn=(revbn*10)+(dn%2);

  dn=dn/2;

  c++;

 }

 while(c>0)

 {

  bn=(bn*10)+(revbn%2);

  revbn=revbn/10;

  c--;

 }

 printf("\nBinary number: %ld",bn);

}

OUTPUT:

Write a C Program to check whether the given number is Armstrong number or not.

SOURCE CODE:

/*Program to check whether the given number is Armstrong number or not.*/

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

 int n,temp,arm=0,c=0;

 clrscr();

 printf("\nEnter number:");

 scanf("%d",&n);

 temp=n;

 while(temp>0)

 {

  temp=temp/10;

  c++;

 }

 temp=n;

 while(temp>0)

 {

  arm=arm+pow((temp%10),c);

  temp=temp/10;

 }

 if(n==arm)

  printf("\nGiven number is Armstrong.");

 else

  printf("\nGiven number is not Armstrong.");

}

OUTPUT:
