make a separate function. [code] bool isPrime(int i) { /* logic here */ }; //somewhere inside main if( isPrime(i) == true ) cout <<" Prime \n" ; else cout <<" not a prime\n"; [/code] Of course this code depends on isPrime function. You should try to create that on your …

what is your program supposed to do?

I think you want it to be this : [code] static float calcTaxes(float grossPay) { float netPay ; if (grossPay <= 300) netPay = (float) (grossPay - (grossPay * 0.15)); if (grossPay <= 450) netPay = (float)(grossPay - (grossPay * 0.20)); else if (grossPay > 450) netPay = (float)(grossPay - …

[code] //assume vec2d is a 2 d vector vector< data_type > copyRow( vec2d[0].begin(), vec2d[0].end()); [/code] That would copy the row 0 onto copyRow vector

How about you just ask your teacher since it will be easier and more straight forward.

[QUOTE=BeyondTheEye;1014631]You might want to change your destructor. [CODE=CPP]delete [] st;[/CODE] instead of [CODE=CPP] delete st; [/CODE] You'll be creating memory leaks if you don't.[/QUOTE] Not memory leak, but undefined behavior.

A side note : one of the main reason call by reference was created is because passing a class object by value is expensive. You can think of Pass by reference like a pointer in disguise.

You could make your code cleaner by using functions, assumming you have learned them already. Not tested. [code] #include<iostream> #include<cmath> using namespace std; bool isPrime(int i) { if(i == 2) return true; for(int j = 2; j < i; j++) //you could optimize but this is for simplicity. if( i …

[QUOTE=soumenpandit;1013101]what is array of pointer[/QUOTE] Well a pointer is an array in some way, so you can think of it as a array of arrays, or a 2d array. [code] //Both Similar char *A[2] = { "hello", "world" }; char B[10][10] = { "hello", "world" }; [/code] They are both …

iostream and cstdlib are called libraries. They contain many methods/functions that will help you from printing to screen to seeding random numbers to sorting arrays, and many more. The #<...> is just the syntax for C++. In java the syntax is import java.SomeLibrary. Each language has is own ways, some …

which part do you need the help with? Mean = average = Sum of Total elements / Number of elements Median is the middle number in a sorted set of numbers Mode is the most occurring number. To find the Mean you can sum up the total and divide by …

Use vectors if you could, if not then something like this will work : Although its not tested, its the general idea. [code] int base= 10; int * Array = new int[base]; bool end = flase; int i = 0; while(!end) { cout <<" Enter a number : " ; …

Easy way out, just put a condition to check if "i" is at .size() - 1; if not then print or else not print.

A few( maybe 2) for loops could solve this problem. Have a for loop, for variable " i" and "a". The equation is pretty forward, unless you don't know what the sigma notation does. What is the "X" variable represents? Is it the user's input ?

Wow, this is funny. Hey, I have a lot of exams right now and I am broke, can you just give me couple of thousands of dollars, so I don't have to work? Just mail it to me.

"Save" the original content, someway, and compare it later on. There is no other way.

Admin, perhaps it would serve this user best, if you move this thread to game development forum.

The compiler just translate it into binary. You could either, get the input as hex, or decimal or octal. You can't get the input as a number and determine if its decimal or hex. Just get it as hex, and the convert it into decimal if you want or need …

[code] int Num = -1; cin >> Num; //get input while( Num < 0 ) //while input is less than 0 or negative { cout <<" Enter a positive number : "; cin >> Num; } [/code]

what is your definition of "trinagle in c " ?

there is a lot of logic errors, but this one is a compile time error : [code] cin << yesorno;[/code] you mean cin >> yesorno , right.

Look at your other post. And don't double post. Be patience.

If this is what you mean. BTW, where is the pointers. And a rule of thumb, when you are using char *, instead of string, you have a bug(In my opinion); [code] //str is the string passed. Key is the key that seperates the word //does not use pointers. void …

Maybe this will help : [code] #include<iostream> using namespace std; int main() { for(int i=5;i>=1;i--) { for(int j=5-i;j>=1;j--) { cout<<"-"; } for(int k=1;k<=i;k++) { cout<<"* "; } cout<<endl; } return 0; } [/code] Look at the output, and trace the loop from i = 5 till i = 1.

Yes. In fact thats very common, using 1d array as a mimic of a 2d. [code] final int ROW = 5; final int COL = 5 char[] Letters = new char[ ROW * COL]; for(int i = 0; i < ROW * COL; i++) Letters[i] = (char)( 'A' + i …

It would help if you created a few function that returns either lowercase, uppercase , number or a punctuations.
