Artemon [7]

Yeah, Your steps ar correct. Let's analyse those steps more easily by the following steps:

\Large{ \boxed{ \bf{ \color{aqua}{Freeze \: panes:}}}}

Freeze panes is a feature in spreadsheet applications, such as Microsoft Excel, LibreOffice Calc, and Google Sheets. It "freezes" a row or column, so that it is always displayed, even as you navigate the spreadsheet.

❍ Freezing panes is especially useful if your spreadsheet has a header row, that you want to always be visible.

  • Select the row below the row(s) you want to freeze. In our example, we want to freeze rows 1 and 2, so we'll select row.
  • Click the View tab on the Ribbon.
  • Select the Freeze Panes command, then choose Freeze
  • Panes from the drop-down menu. ...
  • The rows will be frozen in place, as indicated by the gray line.

       // to set all the locks to a false NOTE:  first locker is the number 0. Last locker is the 99.

       for (int_i=1;i<locker_length; i++)

       {

       locker[i] = false;

       }

       // first student opens all lockers.

       for (int i=1;i<locker.length; i++)        {

       locker[i] = true;

       }

       for(int S=2; S<locker.length; S++)

       {

          for(int k=S; k<locker.length; k=k+S)

          {

              if(locker[k]==false) locker[k] = true;

              else locker[k] = false;      

          }            

       }

       for(int S=1; S<locker.length; S++)

       {

           if (locker[S] == true) {

               System.out.println("Locker " + S + " Open");

           }

Write a program that defines a type for a structure that stores information on a student in ENG EK 125. Declare two variables to
Mashcka [7]

Answer:

Following are the program in the C Programming Language.

#include<stdio.h> //header file

#include<string.h> //header file

struct student//creating structure

{

 //set integer variables

int marks;

int roll;

};

//define function

void initial(struct student *stu)

{

 //set integer type variables

int marks=420;

int roll_no=45,i;

stu->marks=marks;//assigning the values

stu->roll=roll_no;//assigning the values

}

//define main method to call the function

int main()

{

struct student stu;

initial(&stu);//calling the function

printf("Total marks : %d\n",stu.marks); //print output

printf("Roll No. : %d\n",stu.roll); //print output

return 0;

}

<u>Output:</u>

Total marks : 420

Roll No. : 45

Explanation:

Here, we define the structure "student" with a struct keyword for creating a structure.

  • inside the structure, we set two integer type variable "marks", "roll".

Then, we define a function "initial()" and pass an argument in the parameter of the function.

  • inside the function, we set two integer type variable "marks", "roll_no" and assign the value in the variable "marks" to 420 and variable "roll_no" to 45.
  • Assign the value in the structure's integer variables from the function's variable.

Finally, we set the main method inside it we call the function "initial()" and pass the value and then, we print the output with message.

// class definition

class Main

{

   // method that return sum of two sale value

   public static int Add(int euroSales,int asiaSales)

   {

       // return the sum

       return euroSales+asiaSales;

   }

   //main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // variables

       int euroSales=100;

       int asiaSales=150;

       int eurasiaSales;

        // call the function

       eurasiaSales=Add(euroSales,asiaSales);

        // print the sum

       System.out.println("total sale is:"+eurasiaSales);

   }catch(Exception ex){

       return;}

}

}

Explanation:

Declare and initialize two variables "euroSales=100" and "asiaSales=150". Declare another variable eurasiaSales. Call the method Add() with euroSales and asiaSales as parameter. This method will add both the value and return the sum.This sum will be assigned to variable eurasiaSales.Then print the sum.

Output:

total sale is:250
