Question Aim: To calculate the volume of a sphere

King Mohamed cpp-programming ,

Question: Write a block of code that prompts user to enter the radius, then compute and output the volume of a sphere. (Recall that volume V of a sphere of radius r is given by V = (4/3)PIr3 and assume PI = 3.14

Solution

if(r <= 0) This condition ensures that the radius cannot be zero or negative

Question 5: Write c++ program check if the employee is eligible for bonus or not

King Mohamed cpp-programming ,

Question 5: The current year and the year in which the Songea Teachers College employee joined the institution entered through the keyboard. if the number of years for which the employee has saved the college is greater than 10years,then the bonus of Tsh.250,000/= is given to the employee. if the years of the service is not greater than 10year,then the program should not do anything

Write c++ program check if the employee is eligible for bonus or not

Solution

#include<iostream>

using namespace std;

int main(){

int a,b,d;

cout<<"Enter the current year\n";

cin>>a; /*a implies the current year*/

cout<<"Enter the year an employee joined the institution\n";

cin>>b; /*b implies the year of joining the institution*/

d = a - b; /*Gets the difference of two years*/

if(b > a){

cout<<"The current year cannot be less than the year in which an employee joined the institution\n";

}else{

if(d >= 10){

cout<<"\nAn employee is eligible for the bonus of Tsh.250,000/=\n";

}else{

cout<<"\nAn employee is not eligible for the bonus of Tsh.250,000/=\n";

}

return 0;

cout<<"Enter the number of books to be sold\n";

cin>>n;

cout<<"Enter the price per book to be sold\n";

cin>>price;

if(n >= 1000){

the_discount = price * DISCOUNT;

n_price = price - the_discount;

cout<<"Total books: "<<n<<endl;

cout<<"Original price per book: "<<price<<endl;

cout<<"Price after discount: "<<n_price<<"\n\n";

cout<<"Total costs: "<<(n_price*n)<<".00"<<endl;

}else{

cout<<"Total books: "<<n<<endl;

cout<<"Original price per book: "<<price<<endl;

cout<<"Price after discount: "<<"No discount"<<"\n\n";
