Write A Java Program to Input Marks of Five Subjects of a Student and Calculate the Total, Average, And Percentage of All Subjects.

 

write a program to store the marks of 5 subjects and take the total, after that calculate average, to get average divide the variable to 5.0. and to get the percentage  divide the variable into 500.0 and multiply it to 100

3. Data Type Int Variable with Value

 

2. Arithmetic Operator

 

1. My First Code.

         1. Any line starting with // is a comment

        2. #include <iostream> to use cout that allows us to print output on the screen.
        3 using namespace std; statement so we can use nicknames for our variables
        4. int main() {...} A valid C++ program must have the main() function. The curly braces indicate the start and the end of the function.
        5. cout in our program to print output on the screen.
        6. cout << "Hello World!"; The execution of code beings from this function.
        7. The return 0; statement is the "Exit status" of the program.
        Note: ; is used to indicate the end of a statement.

        CODE


        #include <iostream> // to use input and output   
 
       using namespace std; // use nickname to variables

        int main() // main function

        { // open curly braces or tag

        cout<<"Hello Boyswillcode!"<<endl;

       // cout<< is the code for saying print out
      // endl means endline

        return 0; // return the value from zero

        } // closing tag or curley braces

A program that reads an integer that is typed in by the user and computes and prints the square of that integer.

 Section 2

1. Example of a while loop that simply prints out the numbers 1, 2, 3, 4, 5:

2.  Simple program that will compute the amount of interest that is earned on an investment over a period of 5 years.  

3. This program prints out a 3N+1 sequence starting from a positive integer specified by the user.  It also counts the number of terms in the sequence, and prints out that number. 

4. This program reads a sequence of positive integers input by the user, and it will print out the average of those integers.

12.  program that will compute the amount of interest that is earned on an investment over a period of one year. with user input 

9. Write A Java Program To Input Principle (Amount), Time, And Rate (P, T, R) And Find Compound Interest.

A variable

        int numberOfStudents;

        String name;

        double x, y;

        boolean isFinished;

        char firstInitial, middleInitial, lastInitial;

public class BSIT

{



    public static void main(String[] args)

    {

        int numberOfStudents = 123;

        String name = "bOYSWILLCODE";

        double x = 7.8 , y = 78.5;

        boolean isFinished = true;

        char firstInitial = 'B', middleInitial = 'W', lastInitial = 'C';



        System.out.print("My Student Id is: " + numberOfStudents + " and ");

        System.out.print(" My name is: " + name);

        System.out.print(" My Height is: " + x + " and ");

        System.out.print(" weight is: " + y);

        System.out.print("Am I Really Finish? " + isFinished + " Your Initial is: ");

        System.out.print(firstInitial);

        System.out.print(middleInitial);

        System.out.print(lastInitial);



    }



}

variables with default value

public class BSIT

{



    public static void main(String[] args)

    {

        int numberOfStudents = 123; // variable with default value 

        

        // to add variable to display use the " + " sign without quotation

        System.out.print("My Student Id is: " + numberOfStudents); 

        

    }



}

Output
  My Student Id is: 123
