Write a program in C++ of Armstrong number - Armstrong number in C++ - C++ Armstrong number Program

A Armstrong Number Program in C++:

C program to find Armstrong number : Armstrong numbers are those numbers in which sum of cubes of individual digits is equal to the number. For example 371 = 3³ + 7³ + 1³ = 27 + 343 +1 =371. Another example of Armstrong number is 153 =  1³ + 5³ + 3³ = 1+ 125 + 27 = 153.  Now how we can achieve the same logic using C++ program.

#include<stdio.h>

#include<iostream.h>

#include<conio.h>

void main()

{

int sum=0,n,m;

clrscr();

cin>>n;

m=n;

while(n>0)

{

m=n%10;

sum=sum+(m*m*m);

n=n/10;

}

if(m==sum)

{

cout<<"the given number is amstrong";

}

else

{

cout<<"the given number is not amstrong";

}

getch();

}

A C++ program to count the Armstrong number 1 to 1000:

#include<stdio.h>

#include<conio.h>

main()

{

int r;

long number = 0, c, sum = 0, temp1;

printf("Enter the maximum range upto which you want to find armstrong numbers ");

scanf("%ld",&number);

printf("Following armstrong numbers are found from 1 to %ld\n",number);

for( c = 1 ; c <= number ; c++ )

{

temp1 = c;

while( temp != 0 )

{

r = temp1%10;

sum = sum + r*r*r;

temp1 = temp1/10;

}

if ( c == sum )

printf("%ld\n", c);

sum = 0;

}

getch();

return 0;

}
