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.

An administrator has initiated the process of deploying changes from a sandbox to the production environment using the Force IDE
Pani-rosa [81]

Option A because the environment should be selected for which the changes are to be applied. In a time Force IDE has many project environments for example maybe a java project and C++ project would be there on sandbox, so the environment selection is important.

Option B because the related changed sets should be specified so that other developers that have access to the project can see the changes being made.

Option D The data fields that are needed to be deployed should also be provided so that the updated version can be seen by other developers.

Rejected Options :

Option C user name and password has nothing to do with the production environment because if the user has it only then it can come and make changes.
