Lab 1 (1 page, 6 Exercises)

Exercise 1

Write a C++ program that outputs on the screen the following text: Welcome to the CS140 ''Computer Programming 1'' Lab.

#include <iostream>

using namespace std;
int main() {
    
    cout<<"Welcome to the CS140 "Computer Programming 1" Lab."<<endl;
    
    return 0;
}

Exercise 2

Write a C++ program that outputs on the screen the following patterns:

*****         *****           *                *

*****         *      *         ***           *     *

#include <iostream>

using namespace std;
int main() {

    cout<<"*****     *****        *         * "<<endl;
    cout<<"*****     *   *       ***       * * "<<endl;
    cout<<"*****     *   *      *****     *   *"<<endl;
    cout<<"*****     *   *       ***       * * "<<endl;
    cout<<"*****     *****        *         * "<<endl;
    return 0;
}

Exercise 3

Write a C++ program that computes the sum of the different grades (Labs, Midterms, Final) obtained in the CS140 course for a given student. The program should ask the user to enter the grade for each evaluation. You should stick to the following output.

Lab 1 (0 - 10): 6

Lab 2 (0 - 10): 7.5

Midterm 1 (0 - 20): 16.5

Midterm 2 (0 - 20): 18.5

Final (0 - 40) : 26.5

Sum = 75

#include <iostream>
using namespace std;
int main()
{
    int lab1,lab2,midterm1,midterm2,final,sum;
    cout<<"Lab1 (0 - 10): ";
    cin>>lab1;
    cout<<"Lab2 (0 - 10): ";
    cin>>lab2;
    cout<<"midterm1 (0 - 20):";
    cin>>midterm1;
    cout<<"midterm2 (0 - 20):";
    cin>>midterm2;
    cout<<"final (0 - 40): ";
    cin>>final;
    sum=lab1+lab2+midterm1+midterm2+final;
    cout<<"Sum = "<<sum;
    
    return 0;
}

Exercise 4

Write a C++ program determines whether a number n given by the user is even or odd.

#include <iostream>
using namespace std;
int main()
{
    int n;
    cout<<"enter the number";
    cin>>n;
    if(n%2==0)
    {
        cout<<"even";
    }
    else cout<<"odd";
    return 0;
}

Exercise 5

Write a C++ program determines whether a number n given by the user is a multiple of 3 or not.

#include <iostream>
using namespace std;
int main()
{
    int n;
    cout<<"enter the number";
    cin>>n;
    if(n%3==0)
    {
        cout<<"multiple of 3";
    }
    else cout<<"not multiple of 3";
    return 0;
}

Exercise 6

Write a C++ program that determines the maximum of 3 numbers a, b, and c given by the user. 

#include <iostream>
using namespace std;
int main()
{
    int a,b,c;
    cout<<"enter 3 numbers:";
    cin>>a;
    cin>>b;
    cin>>c;
    int max=a;
    if(b>max)
    max=b;
    if(c>max)
    max=c;
    cout<<"biggest number is "<<max;
    return 0;
}
