Question

solve the linear congruence 17x≅9(mod 276), by using Chinese Remainder Theorem.

Answer 1

#include <stdio.h>
#include <iostream>


using namespace std;


int main()
{
cout << "Enter number of subjects: ";
int n = 0;
cin >> n;
double grad = 0;
cout << endl;
for (int i = 0; i < n; ++i)
{
cout << "Enter grade of " << (i+1) << " subject: ";
double g = 0;
cin >> g;
grad += g;
}
grad /= n;
cout << endl << "Your average is " << grad << endl;


cin.get();
cin.get();
return 0;
}
