// C++ program to find all angles of a triangle if two angles are given
#include <iostream>
using namespace std;

int main() {
    int p, q, r;
    
    // p, q, and r is all angles of the triangle

    cout << "Enter the two angles of triangle::\n";
    cin >> p >> q;

    // Compute third angle
    r = 180 - (p + q);

    // Output
    cout << "\nThird angle of the triangle = " << r;
    return 0;
