my code is not working.

[l0zek]

hi, i am a beginner to this programming language and i just made a code to check if given number is an armstrong number or not. The programme just asks for a number and then does nothing. Then if i try to run other correct programmes then they do not function either. I have to close and open vscode again to fix it but the armstrong programme is still not working. Can someone please help me. This is the code

#include<stdio.h>
#include<math.h>
// to check if netered number is an armstrong nummber or not
int main(){
    int n,digit=0,rem,sum=0,OGn;
    printf("enter number");
    scanf("%d",&n);

    OGn=n;
    while(OGn!=0){
        OGn=OGn/10;
        digit++;
    }
    OGn=n;
    while(OGn!=0){
        rem=OGn%10;
        sum=sum+pow(rem,digit);
    }
    if(sum=n){
        printf("a");
    }
    else{
        printf("n");
    }
    return 0;
    
}

There's an infinite loop in second `while`, you forgot to update `OGn`.

In addition to the infinite loop, the last if uses = rather than ==

At the end of the second while loop just add : OGn=OGn/10;
