Real Fancy in C++

A program was written by my friend Thomas to test real fancy in C++. Thank you Thomas for sharing your code to us.

Program Listing

Chef was reading some quotes by great people.

Now, he is interested in classifying all the fancy quotes

he knows. He thinks that all fancy quotes which contain

the word "not" are Real Fancy;

quotes that do not contain it are regularly fancy.

You are given some quotes.

For each quote, you need to tell Chef if it is Real Fancy

or just regularly fancy.

Temperature Checker in C++

A simple program that I wrote using C++ to ask the user to give a temperature and then the program will check the type of temperature based on the given value of the user using if-else if statement.

Program Listing

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

int temp;

cout << "Enter temperature: ";

cin >> temp;

if((temp>=31)&&(temp<=50))

cout << "VERY HOT";

else if((temp>=21)&&(temp<=30))

cout << "WARM";

else if((temp>=11)&&(temp<=20))

cout << "VERY COLD";

else if((temp>=0)&&(temp<=10))

cout << "FREEZING";

getch();

return 0;

}

Area of the Triangle in C++

A simple program that I wrote that will ask the user to give base and height value to compute the are of the triangle using a C++ programming language.

Program Listing

#include<iostream>

#include<cstdlib>

using namespace std;

int main()

{

double b,h;

cout<<"Area of a Triangle Solver"<<endl;

cout<<"base : ";

cin>>b;

cout<<"height: ";

cin>>h;

cout<<"area = "

<<(b*h)/2

<<" square units "

<<endl;

system("pause");

return 0;

*/

using System;

namespace ConsoleApp1
{
   class Program
   {
     static void Main(string[] args)
     {
       const int N = 5;
       int[] numbers = new int[N];
       int num_to_search;
       string buffer;

       for (int i = 0; i < N; ++i)
