Tax Rate Table

[Nickolas Baker]

First time programmer here. Maybe I am going about this the wrong way, but I am trying to figure out how to fill in the rest of the table. Here is the code:

#include <iostream>
#include <iomanip>

using namespace std;

int main ()
{
double s,
t;

cout << setprecision(2)
<< setiosflags(ios::fixed)
<< setiosflags(ios::showpoint);

cout << " Amount Tax Rate" << endl;
cout << " ---------------------------------------------------------------------" << endl;
cout << " 4.0% 4.5% 5.0% 5.5% 6.0% 6.5% 7.0%" << endl;
cout << endl;

{
for (t = .04; t <= .07; t += .05)
for (s = 100; s <= 1000; s += 100)
cout << " " << setw(10) << s << setw (10) << t * s << endl;
}
return 0;
}

I understand why you're doing the for loops the way you are, but the way you're handling it is confusing you.
for (t = .04; t <= .07; t += .05)
This will only fire once, you're increasing it by 5%. It should read, if I'm understanding the intent properly:
for (t = .04; t <= .07; t += .005)
With this, it will increase the tax by 0.5% per iteration, allowing you to calculate the 4.5%, 5.0%, 5.5%, etc tax brackets.

This is why you increment counters and calculate variables.

const int s = 100;
double t[7] = {.04, .045, .05, .055, .06, .065, .07};

for(int i = 0; i < 7; i++){
    for(int j = 1; j <= 10; j++){
        cout << " " << setw(10) << s * j << setw(10) << t[i] * (s * j) << endl;
    }
}

Thank you. For some reason the program is calculating but the output is not a table form? any suggestions?

Try this:
cout << " " << setw(10) << s * j << setw(10) << t[i] * (s * j) << "\n";

still one big column

Post what you're getting and what you're looking for.

this is the current output:

1000 70.00

This is what I need, not going to fill in the whole table. I hope you get the idea.

Amount Tax Rate
---------------------------------------------------------------------
4.0% 4.5% 5.0% 5.5% 6.0% 6.5% 7.0%
100 4.00 4.50 5.0 5.5
200 8.00
300 12.00
400 16.00
500 20.00
600 24.00
700 28.00
800 32.00
900 36.00
1000 40.00

I do get the idea; you set your for loops backwards.

const int s = 100;
double t[7] = {.04, .045, .05, .055, .06, .065, .07};

for(int j = 1; j <= 10; i++){
    cout << "" << setw(10) << s * j;
    for(int i = 0; i < 7; j++){
        cout << " " <<  setw(10) << t[i] * (s * j);
    }
    cout << endl;
}

I got it working. tyvm
