Pretty new to C++, please help

[buddha6279]

Hello, I am new to C++ and thus far have been able to do all the program excercises in my book, but I can't get the following program scenario to build and execute.

I am trying to calculate a salesperson's salary total, the base salary is 400$, plus a bonus of either 5% or 10% of their gross sales for that week.The standard commision is 5% but it is increased to 10% if the weekly sales total is over 1000$

# include <iostream.h>

int main ()
{
cout << "What are your total sales for the week? ";
cin >> Sales;

// do I use an if statement after the code above? So if the user inputs 1100$ it knows to give the 10% bonus? And after that, to have the total salary displayed on the screen, the 400 base salary, plus whatever the comission would be. I'm just really confused on how to program the math operations inside the if statement. PLEASE HELP! THANK YOU!

return 0;

}

math functions inside if statements are very important and pretty easy to use once you get use to how they work.

you can use an if statement, or a switch statement. An if statement for the problem would look like...

cin >> sales;

if ( sales > 1000 )
{
salary = baseSalary + ( sales * .1 )
}

else if ( sales < 1000 )
{
salary = baseSalary + ( sales * .05 )
}

the first if condition is looked at, if it's not valid, it goes to the next one. Inside of each if, you put their commision plus their base salary. The left hand side (the variable) gets the result of the operations on the right.

if(sales > 1100)
  commission = 0.10;
else
  commission = 0.05;
 
total = base + (commission*sales);
// total = 400 + (5% or 10%)*sales

if ( sales > 1000 )
{
salary = baseSalary + ( sales * .1 )
}

else if ( sales < 1000 )
{
salary = baseSalary + ( sales * .05 )
}

This code notably results in a sales person with sales of extactly 1000 getting no bonus at all, salary is left uninitialised.
