Sir, That was by mistake it is supposed to be a=a*10; otherwise I am not able to find any other error. CODE-https://ide.codingblocks.com/s/373711

what you have done here

while(x>a)

    {

        n=x%b;

        b=b*10;

        n=n/a;

        a=a*10;

        count++;

    }

are you want to calculate the no of digits in a number?
then correct way to do that is

// first find the length of num

    int num=n;

    int len=0;

    while(num>0){

        len++;

        num/=10;

    }

now after calculating no of digit of a number

// now check wheter it is armstrong number of not
    int ans=0;

    num=n;

    while(num>0){

        int rem=num%10;

        ans+=pow(rem,len);

        num=num/10;

    }

    if(ans==n)cout<<"true\n";

    else cout<<"false\n";
