#include<iostream> using std::cin; using std::cout; using std::endl; bool ISPositive(int i) { if(i<0) return false; else return true; } int main(void) { int num; bool result; cout <<"숫자입력 : "; cin >> num; result = ISPositive(num); if(result==true) printf("Positve number\n"); else printf("Negative number\n"); return 0; }
#include<iostream> using std::cout; using std::endl; int main(void) { int BOOL=true; cout << "Bool : " << BOOL <<endl; BOOL = false; cout << "Bool : " << BOOL <<endl; return 0; }
