Although the memory's not deallocated in the main function, it's not a big issue in this test problem.
void counterspell(Spell *spell) { Fireball *foo1 = dynamic_cast<Fireball*>(spell); Frostbite *foo2 = dynamic_cast<Frostbite*>(spell); Waterbolt *foo3 = dynamic_cast<Waterbolt*>(spell); Thunderstorm *foo4 = dynamic_cast<Thunderstorm*>(spell); if(foo1 != NULL) { foo1->revealFirepower(); } else if(foo2 != NULL) { foo2->revealFrostpower(); } else if(foo3 != NULL) { foo3->revealWaterpower(); } else if(foo4 != NULL) { foo4->revealThunderpower(); } else { string X = spell->revealScrollName(); string Y = SpellJournal::read(); int m = X.size(); int n = Y.size(); int L[m+1][n+1]; int i, j; for (i = 0; i <= m; i++) { for (j = 0; j <= n; j++) { if (i == 0 || j == 0) L[i][j] = 0; else if (X[i-1] == Y[j-1]) L[i][j] = L[i-1][j-1] + 1; else L[i][j] = max(L[i-1][j], L[i][j-1]); } } cout << L[m][n] << endl; } }
