Working on homework, hit a snag

Hey guys,

I'm in my first year of community college, trying to learn C++ for the first time. I'm running into a snag on my homework though. I've got 99% of the code, but continually get the same error when i try to compile it.

The code is supposed to Ask whether someone is an Instate student. If yes, tuition =

here's the code:

Code:

---

#include <iostream>
using namespace std;


int main()
{
    int numCredHour = 0;
    double totTuition = 0;
    char letter = ' ';
   
   
    cout<<"Are You An In-State Student?"<<endl;
    cin>>letter;
    cout<<"How Many Credit Hours Do You Have?"<<endl;
    cin>>numCredHour;
   
    if(toupper(letter) == 'Y'&& numCredHour < 10)
    {
          totTuition=numCredHour*50;
          cout<<"Your Total Tuition is: $"<<totTuition<<endl;
          }
            else(numCredHour>10);
            totTuition=500;
              cout<<"Your Total Tuition is: $500"<<endl;
    if (toupper(letter) == 'N' && numCredHour<15);
    {
          totTuition=numCredHour*400;
          cout<<"Your Total Tuition is: $"<<totTuition<<endl;
          }
    else (numCredHour>15);
          totTuition=6000;
          cout<<"Your Total Tuition is: $6000"<<endl;
system("pause");
return 0;
}

---

The error code i get is:

Quote:

---

30 C:\Users\******\Prog1.cpp expected primary-expression before "else"

---

and

Quote:

---

30 C:\Users\******\Prog1.cpp expected `;' before "else"

---

Any ideas as to what might fix my issue would be greatly appreciated. I'll be checking back here every couple of minutes while I work on the next few programs. Thanks for any and all who help!

Code:

---

            else(numCredHour>10);
            totTuition=500;
              cout<<"Your Total Tuition is: $500"<<endl;

---

in line 1 the semicolon must be removed and actually i want to remind you to use braces when you are a beginner.When not using braces the compiler assumes that body of the if statement is only the very next line.No error is going to be produced ,but a possible logical error is on the way

Okay, I think I get what you are saying... So it should look more like this:

Code:

---

#include <iostream>using namespace std;


int main()
{
    int numCredHour = 0;
    double totTuition = 0;
    char letter = ' ';
   
   
    cout<<"Are You An In-State Student?"<<endl;
    cin>>letter;
    cout<<"How Many Credit Hours Do You Have?"<<endl;
    cin>>numCredHour;
   
    if(toupper(letter) == 'Y' && numCredHour < 10)
    {
          totTuition=numCredHour*50;
          cout<<"Your Total Tuition is: $"<<totTuition<<endl;
          }
            else(numCredHour>10)
            {
            totTuition=500;
              cout<<"Your Total Tuition is: $500"<<endl;
              }
    if (toupper(letter) == 'N' && numCredHour<15)
    {
          totTuition=numCredHour*400;
          cout<<"Your Total Tuition is: $"<<totTuition<<endl;
          }
    else (numCredHour>15)
    {
          totTuition=6000;
          cout<<"Your Total Tuition is: $6000"<<endl;
          }
system("pause");
return 0;
}

EDIT: After re-writing and compiling I get error codes stating i need a ; before each {

Can you please post what the compiler actually says? :)

Not a problem :) Dev -C++ compiler is what i am using.

> else (numCredHour>15)
else doesn't have an expression.

You might have meant
else if (numCredHour>15)

But the final else is just that - everything else not matching any previous if / else if

Code:

---

if (toupper(letter) == 'N' && numCredHour<15)
{
    totTuition=numCredHour*400;
    cout<<"Your Total Tuition is: $"<<totTuition<<endl;
}
else (numCredHour>15)
{
    totTuition=6000;
    cout<<"Your Total Tuition is: $6000"<<endl;
}

A quick review shows this mistake - the proper syntax is as follows:

Code:

---

if (condition)
{
    // executes if condition is TRUE
}
else
{
    // executes if condition is FALSE
}

---

Whereas you have:

Code:

---

else (numCredHour>15)

---

That extra line after the "else" statement does not belong there.

If you want the "else" to test another condition, then the proper syntax would be:

Code:

---

if (condition1)
{
    // executes if condition1 is TRUE
}
else if (condition2)
{
    // executes if condition1 is FALSE and condition2 is TRUE
}

---

[EDIT] Too slow...

I love you guys! Everyone was a lot of help. here's the new and updated program code that works flawlessly so far through 5 examples :) Again, thank you!

Code:

---

#include <iostream>
using namespace std;


int main()
{
    int numCredHour = 0;
    double totTuition = 0;
    char letter = ' ';
   
   
    cout<<"Are You An In-State Student?"<<endl;
    cin>>letter;
    cout<<"How Many Credit Hours Do You Have?"<<endl;
    cin>>numCredHour;
   
    if(toupper(letter) == 'Y' && numCredHour < 10)
    {
          totTuition=numCredHour*50;
          cout<<"Your Total Tuition is: $"<<totTuition<<endl;
          }
            if(numCredHour>10 && toupper(letter) == 'Y')
            {
            totTuition=500;
              cout<<"Your Total Tuition is: $500"<<endl;
              }
    if (toupper(letter) == 'N' && numCredHour<15)
    {
          totTuition=numCredHour*400;
          cout<<"Your Total Tuition is: $"<<totTuition<<endl;
          }
    else if(numCredHour>15)
    {
          totTuition=6000;
          cout<<"Your Total Tuition is: $6000"<<endl;
          }
system("pause");
return 0;
}

If you know of a better way for me to write this up, any and all advice is welcome. Knowledge is my drug :)

EDIT: Found a little snag in it, but fixed it with the advice you guys gave me. Changed the code i had here, and put up the new one. THanks again for all the help

It also help to format your code consitently so you can actually see the blocks clearly. See this

My only excuse is that i just arrived in swiss for a scholarship and i am 'out of my environment'...

Thanks! That helps a lot! my main problem was i was using tabs. lol Now I know why it wasn't acting right! and 'white space' does definitely clean it up.

EDIT: If I run into any more snags, I'll definitely come back to this forum. Everyone was a big help! Wish me luck on the last 3 programs.

I recall a very very old thread:

I honestly don't know why I remember it through...
