PROGRAM TO FIND WHETHER THE GIVEN NUMBER IS MAGIC NUMBER OR NOT

/*PROGRAM TO FIND WHETHER THE GIVEN NUMBER IS MAGIC NUMBER OR NOT*/

A number is said to be a magic number if the reverse of the square of the number is equal to the given number reverse and its sqaure.

for eg: (12) sqaure =144 reverse of 144 is 441
            (21) square= 441

             (13) square=169 reverse of 169 is 961
             (31) sqaure=691

program:

// prg to illustrate magic number

#include<stdio.h>
void main()

{

int j,i,k,n,temp;

printf("\nENTER ANY NUMBER:");

scanf("%d",&n);
temp=n;
while(i > n)

{
       i=n*n;
    j=0;
    while(i>0)
    {
        j=j*10 + i% 10;
        i=i/10;
    }
    i=n;
    k=0;
    while(i>0)
    {
        k=k*10+i%10;
        i=i/10;
    }
    if(k*k==j)
    printf("\n%d is a Magic number\n ",temp);
    else
         printf("\n%d is not a Magic number\n ",temp);
}
}
output:

MAGIC NUMBER IN BETWEEN MIN AND MAX VALUES

/*PROGRAM TO FIND WHETHER THE GIVEN NUMBER IS MAGIC NUMBER OR NOT*/

A number is said to be a magic number if the reverse of the square of the number is equal to the given number reverse and its sqaure.

for eg: (12) sqaure =144 reverse of 144 is 441
            (21) square= 441

             (13) square=169 reverse of 169 is 961
             (31) sqaure=691

program:
// prg to illustrate magic number in between min and max values

#include<stdio.h>
void main()

{

int min,max,j,i,k,n;

printf("\nEnter min value:");

scanf("%d",&min);

printf("\nEnter max value:");

scanf("%d",&max);
printf("\nMagic numbers are:");

for(n=min ;n<=max;n++)

{

       i=n*n;
    j=0;
    while(i>0)
    {
        j=j*10 + i% 10;
        i=i/10;
    }
    i=n;
    k=0;
    while(i>0)
    {
        k=k*10+i%10;
        i=i/10;
    }
    if(k*k==j)

    printf("\n%d is a Magic number\n ",n);

}
}

output:

STRONG NUMBERS IN BETWEEN MIN AND MAX VALUES

// program to illustrate strong number in between min and max values

#include<stdio.h>
void main()
{
int min,max,n,i,r,sum=0,temp,fact;
printf("\nEnter min value:");
scanf("%d",&min);
printf("\nEnter max value:");

while(temp)
{

r=temp %10;
while(i <= r)
{
fact = fact * i;
i++;
}
sum=sum +fact;
temp = temp /10;
}
if(sum==n)
printf("\n %d is a strong number \n",n);
}
}

output:

PROGRAM TO FIND WHETHER THE GIVEN NUMBER IS STRONG OR NOT

A NUMBER IS CALLED STRONG NUMBER IF SUM OF THE FACTORIAL OF ITS DIGIT IS EQUAL TO NUMBER ITSELF

FOR EXAMPLE: 145

I FACTORIAL IS 1

4 FACTORIAL IS 24

5 FACTORIAL IS 120

THEREFORE 1 + 24 +120 = 145

PROGRAM:

// prg to illustrate strong number

#include<stdio.h>

void main()
{
int n,i,r,sum=0,temp,fact;
printf("enter any number:");
scanf("%d",&n);
temp=n;
while(n != 0)
{
i=1,fact=1;
r=n %10;
while(i <= r)
{
fact = fact * i;
i++;
}
sum=sum +fact;
n = n /10;
}
if(sum==temp)
printf("%d is a strong number \n",temp);
else
printf("%d is not a strong number \n",temp);
}

output:

ARMSTRONG NUMBERS IN BETWEEN MIN AND MAX VALUES

// prg to illustrate Armstrong numbers in between min and max values

#include<stdio.h>

void main()

{

int min,max,n,r,arm=0,temp;

printf("\n Enter min value :");

scanf("%d",&min);

printf("\n Enter max value :");

scanf("%d",&max);

printf("\n Armstrong number in the given range :");

for(n=min ; n<=max ; n++)

{

   temp=n,arm=0;

   while(temp != 0)

     {

      r = temp % 10;

      temp = temp / 10;

      arm = arm + (r * r * r);

     }

     if( n == arm )

       printf("\n%d is an armstrong \n",n);

}

}

output:

PROGRAM TO FIND WHETHER THE GIVEN NUMBER IS ARMSTRONG OR NOT

THOSE NUMBERS WHOSE SUM OF ITS DIGITS TO POWER OF NUMBER OF ITS DIGITS IS EQUAL TO THAT NUMBER ARE KNOWN AS ARMSTRONG NUMBER

FOR EXAMPLE: 153

TOTAL DIGITS IN 153 IS 3

THEREFORE = 1^3 + 5^3 +3^3

= 1 + 125 + 27

= 153

FOR EXAMPLE: 1634

TOTAL DIGITS IN 1634 IS 4

THEREFORE = 1^4 + 6^4 + 3^4 + 4^4

= 1 + 1296 + 81 + 64

= 1634

// prg to illustrate given number is Armstrong or not

#include<stdio.h>
void main()
{
printf("enter any number:");

int n,r,arm=0,temp;

scanf("%d",&n);

temp=n;

while(n != 0)

{

   r = n % 10;

   n = n / 10;

   arm=arm + (r * r * r);

}

if( temp == arm )

   printf("%d is an armstrong \n",temp);

else

   printf("%d is not a armstrong \n",temp);

}
