C++ Programming: Days of the week

Write a program that will ask the user to input an integer then output the equivalent day of the week. 1 is Sunday, 2 is Monday and so on. If the inputted number is not within 1-7, output "Day is not available!"

Solution:
#include <iostream>
using namespace std;

int main()

int day; 
cout<<"Enter a number from 1 to 7: "; 
cin>>day; 
switch (day) 
 { 
 case 1:  
   cout<<"Sunday"<<endl; 
   break; 
 case 2:  
   cout<<"Monday"<<endl;  
   break; 
 case 3:  
   cout<<"Tuesday"<<endl;  
   break; 
 case 4:  
   cout<<"Wednesday"<<endl;  
   break; 
 case 5:  
   cout<<"Thursday"<<endl;  
   break; 
 case 6:  
   cout<<"Friday"<<endl;  
   break; 
 case 7:  
   cout<<"Saturday"<<endl;  
   break; 
 default:  
   cout<<"Day is not available!"<<endl; 
 }
}

C++ Programming: Salary

Write a program that asks the user for the hours worked for the week and the hourly rate. The basic salary is computed as:

salary = hours worked * hourly rate

Bonuses are given:

No. of hours > 45    |   Bonus of 500 pesos
No. of hours > 40 and <=45   |   Bonus of 250 pesos
No. of hours > 35 and <=40   |   Bonus of 150 pesos

Display the basic salary, bonus and the total salary (basic salary + bonus) for the week.

Solution:
#include <iostream>
using namespace std;
int main()
{
float amount, hours, bonus, total;
cout<<"Enter hours worked: ";
cin>>hours;
cout<<"Enter the hourly rate: ";
cin>>amount;

if (hours >45)
bonus = 500;
else if (hours > 40 && hours <=45)
bonus = 250;
else if (hours >35 && hours <=40)
bonus = 150;
else
bonus = 0;

total= (hours*amount) + bonus;
cout<<"The basic salary is "<< hours*amount<<endl;
cout<<"The bonus is "<<bonus<<endl;
cout<<"The total salary is "<<total<<endl;

return 0;
}

C++ Programming: Smallest Number

Problem: Write a C++ program that finds the smallest among the five integers inputted by the user.

Solution #1:
#include <iostream>
using namespace std;
int main()
{
int a,b,c,d,e,smallest;
cout<<"Enter five numbers \n";
cout<<"Number 1: ";
cin>>a;
cout<<"Number 2: ";
cin>>b;
cout<<"Number 3: ";
cin>>c;
cout<<"Number 4: ";
cin>>d;
cout<<"Number 5: ";
cin>>e;
smallest = a;
if (smallest >b)
    smallest = b;
if (smallest >c)
    smallest = c;
if (smallest >d)
    smallest = d;
if (smallest >e)
    smallest = e;

cout<<"The smallest number is "<<smallest<<endl;
return 0;
}

Solution #2
#include <iostream>
using namespace std;
int main()
{
int a,b,c,d,e;
cout<<"Enter five numbers \n";
cout<<"Number 1: ";
cin>>a;
cout<<"Number 2: ";
cin>>b;
cout<<"Number 3: ";
cin>>c;
cout<<"Number 4: ";
cin>>d;
cout<<"Number 5: ";
cin>>e;
if (a<b && a<c && a<d && a<e)
    cout<<"The smallest number is "<<a<<endl;
else if (b<a && b<c && b<d && b<e)
    cout<<"The smallest number is "<<b<<endl;
else if (c<a && c<b && c<d && c<e)
    cout<<"The smallest number is "<<c<<endl;
else if (d<a && d<c && d<c && d<e)
    cout<<"The smallest number is "<<d<<endl;
else 
    cout<<"The smallest number is "<<e<<endl;

return 0;
