PROBELM FACING IN TEST CASES

#1

MY 1 TEST CASE AND 2 ND TEST CASE IS NOT CORRECT WHY ??
PLEASE HELP ME IN THIS.

#include
using namespace std;
bool checkArmstrongNumber(int num);

int main(){
int num;
bool flag;
cout<<"Enter a positive integer: ";
cin>>num;
flag = checkArmstrongNumber(num);
if(flag == true)
cout<<“yes”;
else
cout<<“no”;

return 0;
}
bool checkArmstrongNumber(int num) {
int temp, sum=0, digit;
bool isArm;
temp = num;
while(temp != 0) {
digit = temp % 10;
sum = sum +(digit * digit * digit);
temp = temp/10;
}
if (sum==num)
isArm = true;
else
isArm = false;

return isArm;
}

hello @naval16

this is not required.
check output format of the given problem and then print only that thing which is mentioned in output format.

#3

#include
using namespace std;
bool checkArmstrongNumber(int num);

int main(){
int num;
bool flag;
cin>>num;

//Calling function
flag = checkArmstrongNumber(num);
if(flag == true)
cout<<“yes”;
else
cout<<“no”;

return 0;
}
/* User defined function that checks whether the passed

  • integer number is Armstrong or not
    */
    bool checkArmstrongNumber(int num) {
    int temp, sum=0, digit;
    bool isArm;

    temp = num;
    while(temp != 0) {
    digit = temp % 10;
    sum = sum +(digit * digit * digit);
    temp = temp/10;
    }
    if (sum==num)
    isArm = true;
    else
    isArm = false;

    return isArm;
    }

IN THIS ALSO , FACING SAME PROBLEM .
ALL TEST CASES ARE WORKING PROPERLY EXCEPT 0 AND 1

MINE CODE IS THIS PLEASE HELP ME IN THIS .

pls check this .

#6

#include
using namespace std;
int fastPow(int a, int b)
{
if(b==0)
return a;

int smallAns = fastPow(a, b/2);
smallAns *= smallAns;
if(b & 1)
     return smallAns*a;

 return smallAns;

}
bool isArmstrong(int n)
{
int noOfDigits = 0;
int m = n;
while (m)
{
noOfDigits++;
m /= 10;
}

m = n;
int sum = 0;
while (m)
{
    int r = m % 10;
    sum += fastPow(r, noOfDigits);
    m /= 10;
}

return n == sum;

}
int main()
{
int num;
cin>>num;
isArmstrong(num) ? cout<<“no”:cout<< “yes” ;

return 0;
}

please help me in this
