Look at this program: int main() {    int x = 4;    displayMessage();    return 0; } void displayMessage() {    for(int x = 1; x <= 100; x++)      cout << "I love computer science" << endl; } What will the output be?     Answers: Nothing. It won't compile because you can't define the variable x inside a loop heading.   Nothing. It won't compile because the displayMessage function is being called before it has been defined   "I love computer science" 100 times   "I love computer science"   Nothing. It won't compile because you can't call a void metho

A rod is used to hang a load (force) of 1000 N.There are 4 ingredients with their respective strengths.Create a program to create a bar diameter table, if using the 4 materials.Example: Copper Steel Material. Aluminum. Bronze                 Strength(N/mm2) 2000. 1600. 1400. 1700Rod Diameter:                  Ingredient. Copper Steel. Aluminum. BronzeDiameter. (mm) …. …. …. …..Note: Strength is the maximum stress the material can withstandStress S = force/sectional area S=force/A A = force/SmaxCross-sectional area A = 3.14 x d2 /4 d = root(4xA/3.14)Instructions: Make a list to store the ingredient names and strengths Create in a python program

Computer Science Part C: Interactive Driver Program Write an interactive driver program that creates a Course object (you can decide the name and roster/waitlist sizes). Then, use a loop to interactively allow the user to add students, drop students, or view the course. Display the result (success/failure) of each add/drop.

Online Billing System in Java This java project is based on calculating online bills without any manual calculation. The user just needs to feed the item name, its price, and quantity. The system will generate a bill showing the amount of money to be paid.
