Armstrong cod is giving the error

#1

i have written the code. why is it giving the error. please look into and only explain the corrections which i need to make no solution on ide.

#2

What are you trying to do?

That will help me to highlight your mistakes.

#3

i am writing the code to find out whether the given number is armstrong or not.

#4

Ye, but how are doing that, what is your logic?

#5

where is my logic is wrong? please tell me with line number.

#6

here is my code. please point out my mistake

#include
using namespace std;
bool isarmstrong(int armstong=371){
if(isarmstrong){
cout<<“true”<<endl;
}
else{
cout<<“false”<<endl;
}

}

int main(){
int armstong=371;
isarmstrong(armstong=371);
return 0;

}

#7

Yes, but What do you think this line does

if(isarmstrong)
#8

i am writing function using bool operator and bool operator returns only true or false value. so in this statement i am comparing the number 371 (which is written in function) if it is true then cout<<---- else cout<<----…
what is wrong in it?

#9

No, this is not how you do this.

#10

What is that you want to do?

Take a number and see if it is equal to 371 or not?

#11

see this is the code which i have written in sublime text editor

and it is working fine on my pc but not working good on online judge.

#12 
#include<iostream>
using namespace std;
bool isarmstrong(int armstong=371){
	if(isarmstrong){
		cout<<"true"<<endl;
	}
	else{
		cout<<"false"<<endl;
	}
    return true;
}

int main(){
	int armstong=371;
	isarmstrong(armstong=371);
	return 0;
}

This will work on online judge as well, but I am not sure if it will work in the same way as you want.

#13

this is also not working on online judge. i submitted it and it shows the message that wrong answer.

#14

Yes, because it is definitely wrong.

#15

Here is the correct code

#include <iostream>
using namespace std;

int main() {
    int num, originalNum, remainder, result = 0;
    cin >> num;
    originalNum = num;

    while (originalNum != 0) {
        // remainder contains the last digit
        remainder = originalNum % 10;
        
        result += remainder * remainder * remainder;
        
        // removing last digit from the orignal number
        originalNum /= 10;
    }

    if (result == num)
        cout << num << " is an Armstrong number.";
    else
        cout << num << " is not an Armstrong number.";

    return 0;
}

If this is your first time programming, then leave this problem for some time and try it after some time.
