Most of my problems are showing not shwoing anyputput just compiling

#1

thats my code please help

#2

@chemant077 use this function for calculating the Euler toitent function

int phi(int n)
{

int result = n; // Initialize result as n 



// Consider all prime factors of n and subtract their 

// multiples from result 

for (int p = 2; p * p <= n; ++p) { 

      

    // Check if p is a prime factor. 

    if (n % p == 0) { 

          

        // If yes, then update n and result 

        while (n % p == 0) 

            n /= p; 

        result -= result / p; 

    } 

} 



// If n has a prime factor greater than sqrt(n) 

// (There can be at-most one such prime factor) 

if (n > 1) 

    result -= result / n; 

return result;

}
