Armstrong number and arrays in C Programming

In this article, it is explained the Armstrong number program and the basic details of C Programming. In the next one you will get more details and programs based on C.

Armstrong number

An Armstrong number is one whose sum of digits raised to the power three equals the number itself. 371, for example, is an Armstrong number because 3**3 + 7**3 + 1**3 = 371.

Algorithm

  • Find the number of digits (dc) = exp
  • Separate each digit = base
  • Find base to the power of exp as a result
  • Result, k=k+result
  • if k==x, then it is Armstrong number

Arrays in C

Program

#include<stdio.h>

int main()

{

int x,num,k,result,exp,base,dc,d,j;

Printf("Enter a number:");

Scanf("%d",&x);

if(x<0)

{

Printf("Not an armstrong number");

return 0;

}

num=x;

dc=1;

 While(num>9)

{

dc++;

num=num/10;

}

k=0;exp=dc;

num=x;

While(num>0)

{

d=num%10;

base=d;

result=1;

j=1;

While(j<=exp)

{

result=result*base;

j++;

}

k+=result;

num/=10;

}

if(k==x)

{

Printf(%d is armstrong number\n,x");

}

else

{

Printf(%d is not an armstrong number",x);

}

return 0;

}

Arrays in C

An array is a collection of elements of the same type placed in contiguous memory locations that can be individually referenced by using an index to a unique identifier. Five values of type int can be declared as an array without having to declare five different variables.

To create an array, define the data type (like int) and specify the name of the array followed by square brackets [].

int x[5];

x is an array of 5 elements with indexes from 0 to 4.

Arrays are the derived data type in C programming language which can store the primitive type of data such as int, char, double, float, etc.

Accept 10 numbers in an array. Compute and print the sum.

#include<stdio.h>

int main()

{

int x[10],y,total;y=0;

While(y<=9)

{

Printf("Enter a number:");

Scanf("&d",&x[y]); 

y++;

}

y=0;

total=0;

While(y<=9)

{

total = total+x[y];

y++;

Printf("Total is %d",total);

 return 0;
