Write a program that takes as input a class score. Output the grade for the class based on the

following guideline:

 Exactly 100 is A+

 90and above is A

 80 and above is B

 70 and above is C

 60 and above is D

 Anything less than 60 is F

 Anything more than 100 or less than 0 is invalid input.

Write a program that accepts a letter grade as input and outputs the teacher’s remarks. Use

only switch, do not use any if’s. Example: If ‘A’or ‘a’, then “Excellent job!”. If ‘F’ or ‘f’, then “You

failed. Please study more next time”.

Create a program that asks the user a series of questions that begin, “Is your number bigger than…” in order to deduce what integer between 1 and 100 they are thinking of. The user should only be able to answer ‘y’ or ‘n’ to each question. (Hint: each time round the loop, you should be seeking to halve the range in which number could lie, so store an upper bound and a lower bound, and change one or the other according to the user’s answers).

 Write a program that uses a do-while loop to add integers by the user. In the loop condition, use a variable of type char, in which you can store the user’s answer to the question, “Do you want to enter another number?” when the loop is terminated, the program should output the total of all the inputs. To extend the program, add a nested while loop to ensure the user answers the “…another?” question sensible (with a ‘y’ or ‘n’).

Taru exam is on the head. So she started learning physics. There she learned about Pascal's law. Now she wanted to try an experiment to get a better understanding of the same.

For, the experiment Taru has N buckets (numbered from 1,2,3...N) which all are initially empty.

She has M number of queries. Each query represents an integer that is of 4 types.

• Query 1: Fill all the buckets with water.
• Query 2: Empty all even valued buckets (2, 4, 6 ... N).
• Query 3: Empty all odd number buckets (1, 3, 5, ... N).
• Query 4: Empty all the buckets. (1,2,3...N).

Write an expression involving a logical operator that is true if limit is 55 and speed is greater than 55

Assign and print the roll number, phone number and address of two students having names "Sam" and "John" respectively by creating two objects of the class 'Student'.

First read in an input value for variable numVals. The. Read numVals integer from input and output each integer on a newline after the string “position-“

Ex input 2, 80, 45,

output position-80

position-45

#include <iostream>

musing namespace std;

int main() {

Int numVals;

for(int i=0;I<numVals;I++)
