The assignment is to create a program in which  you need to guess the number the computer was thinking, and if you get it wrong the program tells you if its too high or to small and when you get it right it tells the number of times it took you to get it right.

Here is my code:

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int main (){
int x, secret,y=0;
srand(time(NULL));
secret=(rand()%100+1);
cout<< “I chose  a number between 1-100, can you guess it?: “<<endl;

do {
cout<<“Write your guess:”<<endl;
cin>>x;
y=y + 1;
if(x>secret){
cout<<“Wrong! ” <<x<< ” is too high, try again.”<<endl;
} else {
if (x<secret){
cout<<“Wrong! “<<x<< ” is too low, try again.”<<endl;
}
}
}while(x!=secret);
cout<<“Congratulations you got it right!!”<<endl;
cout<<“It took you “<<y<<” times to get it right.”<<endl;
return 0;
}

1. I included the libraries “cstdlib” and “ctime” so that I could use the srandom function and the time function.
2. Then I named my variables (the integers “x”, “y” and “secret”)
3. I wrote the function of srand and inside the parenthesis I wrote time(NULL) so that the random number is always different.
4. Then I equaled the integer “secret” to the random function “rand” and put %100 +1 to specify that I want a number between 1 and a 100.
5. I added the cout to ask the user for a number.
6. I made a loop called do-while, this means that while a condition is true this loop will repeat, so I did it with the condition that x!=secret, so while the user doesn’t guess the secret number this will repeat itself.
7. Inside the loop I added an if so if x>secret the program tells you your number is too high, and another if so if

So this week my assignment was to ask the user to give me a temperature in Fahrenheit and my program would give the user the temperature in Celsius and tell him the state of water in that temperature.

I included some mastery topics, I used nested ifs, the use of ifs and elses.

It wasn’t hard, I enjoyed this assignment! I thought the use of ifs would be hard but I understood it pretty fast.

If you don’t understand the use of ifs, I’ll explain what I did, so I just put an if and inside that if I added another if and after that if an else. So first I thought okay.. if the degrees in Celsius are more or equal to a 100, water was gas, then inside that if I added if the degrees where less or equal to 0 water was  solid and if it wasn’t neither of them water was liquid.

This is my code:

#include <iostream>
using namespace std;
int main()
{
int F, C;
cout<< “Do you want to convert Fahrenheit to Celsius?”<<endl;
cout<< “And know what is the state of water in that temperature?”<<endl;
cout<< “Let’s begin!”<< endl;
cout<< “What is the temperature in Fahrenheit?”<<endl;
cin>> F;
cout<< “A temperature of “<<F<< ” degrees Fahrenheit is: “<<endl;

C=5*(F-32)/9;
cout<< C << ” degrees Celsius” << endl;
if (C>=100) {
cout<< “Water is in a gas state.”<< endl;
} else {
if (C<=0) {
cout<< “Water is in a solid state.”<< endl;
} else {
cout<< “Water is in a liquid state.”<< endl;
}

}
return 0;
}

And this how it looks once the program runs:
