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.

Program Listing

#include <stdio.h>

int main()

int n, i;

float num[100], sum=0.0, average;

printf("Enter the numbers of data: ");

scanf("%d",&n);

while (n>100 || n<=0)

printf("Error! number should in range of (1 to 100).\n");

printf("Enter the number again: ");

scanf("%d",&n);

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.

#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 "

Ordinal Numbers Using Pascal

As I learned computer programming my first programming language that I have learned is Pascal the compiler that I am using during those days in college in Turbo Pascal 5.0. In this program I would like to reminisce the past by writing a program using Pascal as my programming language to accept a number from the user and then convert the number into ordinal equivalent values. In this sample program I am using Turbo Pascal 5.5 that is widely available right now to download free from any charges over the Internet. This problem I encounter during my college days in our programming class.
