#include<iostream>
using namespace std;
 
int main()

C++ Else If

int time = 22;
if (time < 10) {
  cout << "Good morning.";
} else if (time < 20) {
  cout << "Good day.";
} else {
  cout << "Good evening.";
}
// Outputs "Good evening."

if else in c++

// C program to illustrate If statement
#include <stdio.h>

    return 0;   
}

C++ Else

c++ if else if

if(boolean_expression 1) {

If Else in C++

int time = 20;
string result = (time < 18) ? "Good day." : "Good evening.";
cout << result;
