Need Help, Not sure what I'm doing wrong

[Cambycis]

I have to write a program for class and i have everything done but get an error on the very last line and i'm not really sure why. Here is what i have so far.

#include <iostream>


using namespace std;

int main()
{
int num1 = 0;
int num2 = 0;
{
cout << "Enter Two Numbers To Compare " << endl;
cin >> num1 >> num2;
if (num1<num2)
{
cout << num2 << " is the larger number" << num1 << " and " << num2 << " is the smallest number" << endl;
}
else if (num1>num2)
{
cout << num1 << " is the larger number" << num2 << " and " << num1 << " is the smallest number" << endl;
}
system ("PAUSE");
return 0;
} <------this is where i'm getting the error when i try to compile it

Count your brackets.

[vlad from moscow]

This brace is excess

int num1 = 0;
int num2 = 0;
{

Also your program say nothing if the two numbers are equal.:)

Thanks got it to run but now i'm not getting the output i need but atleast its working. He didn't say anything about if it equaled just which is larger but i will try and figure that one out as well.

output:
Enter two numbers to compare
1
5
5 is the larger number1 and 5 is the smallest number

#include <iostream>


using namespace std;

int main()
{
int num1 = 0;
int num2 = 0;

cout << "Enter Two Numbers To Compare " << endl;
cin >> num1 >> num2;
if (num1<num2)
{
cout << num2 << " is the larger number" << num1 << " and " << num2 << " is the smallest number" << endl;
}
else if (num1>num2)
{

cout << num1 << " is the larger number" << num2 << " and " << num1 << " is the smallest number" << endl;
}
system ("PAUSE");
return 0;
}

I need to display which number is larger and which number is smaller. And i am very much a begginer at this.

[vlad from moscow]

Replace this code

if (num1<num2)
{
cout << num2 << " is the larger number" << num1 << " and " << num2 << " is the smallest number" << endl;
}
else if (num1>num2)
{

cout << num1 << " is the larger number" << num2 << " and " << num1 << " is the smallest number" << endl;
}

with this one

if (num1<num2)
{
cout << num2 << " is the larger number" << " and " << num1 << " is the smallest number" << endl;
}
else if (num1>num2)
{

cout << num1 << " is the larger number" << " and " << num2 << " is the smallest number" << endl;
}

ahhhh, i see what i did now. Thank you very much for the help. Now on to the second one.

[Cambycis]

Project 2 was create a program that will accept a number as input and output whether the number is even or odd. Got it to work just want to make sure it all looks right. Thanks

using namespace std;

int main(int argc, char *argv[])
{

int num;

cout << " Enter number to evaluate " << endl;
cin >> num;
if (num%2==0)
{
cout << num << " is an even number" << endl;
}
else
{
cout << num << " is an odd number" << endl;
}

system("PAUSE");
return EXIT_SUCCESS;
}

Project 3 i'm completely lost
Given the approriate dimensions (ft) to a room and a cost of flooring per square foot, output the total cost of the flooring. The room can be rectangular or circular. the program should hand either case.

[Cambycis]

Can you tell me how this looks so far?

#include <cstdlib>
#include <iostream>

using namespace std;

int main()
{
int choice = 0
double lenght, width, area, costPerSqFt;

cout << Select 1 for rectangle and 2 for a cirle: "
cin >> choice;

if (choice == 1)
{
cout << "Enter the lenght" << endl;
cout << "Enter the width" << endl;
cout << "Enter the costPerSqFt" << endl;

Total Cost = (lenght*width*costPerSqFt)
}

if (Choice == 2)
{
cout << "Enter area of circle" << endl;
cout << "Enter the diamter of the circle" << endl;

Total Cost = (area*diameter=2r*3.1416)

}

cout << "The cost is $" endl:

system("PAUSE");
return EXIT_SUCCESS;
}

[Phil123]

if (choice == 1)
{
cout << "Enter the lenght" << endl;
cout << "Enter the width" << endl;
cout << "Enter the costPerSqFt" << endl;

Total Cost = (lenght*width*costPerSqFt) // what values are currently stored inside of lenght, width, and costPerSqFt?
}

[Cambycis]

Not sure, i'm kinda confused on this one. I started over and this is what i have now but i'm getting stuck on the What is the cost per sq ft line

using namespace std;

int main()
{

int choice = 0;
double rectagular(double cost);
double circular (double cost);

cout << "Flooring Tool!" << endl;
cout << "______________" << endl;

cout << "Enter 1 for rectangular and 2 for circular" << endl;
cin >> choice;
}
cout << "What is the cost of flooring per sq ft" << endl;
cin >> cost;

if (choice == 1)
totalCost = rectangular(cost);
else
totalCost = circular(cost);
cout << fixed << setprecision(2) << "Total cost of Flooring is $" << totalCost << endl;

system("PAUSE");
return EXIT_SUCCESS;
}

[Cambycis]

i'm lost, i'm to new to this and don't think i'm going to be able to get it done. I know it has to be something simple that i am missing and just can't figure it out.

[Cambycis]

#include <cstdlib>
#include <iostream>
double rectangular(double cost);
double circular(double cost);
using namespace std;

int main()
{
int choice = 0;
double cost, totalCost;
while(choice !=1 && choice!=2){
cout << "1. Rectangual Room" <<endl;
cout << "2. Circular Room" <<endl;
cin >> choice;
}
cout << "What is the cost of flooring per sq ft?: ";
cin>> cost;

if (choice == 1)
totalCost = rectangular(cost);
else
totalCost = circular(cost);
cout << fixed << setprecision(2) << "Total cost of Flooring is: $" << totalCost <<endl; <--this is where i'm getting my problem at
return 0;
}

double rectangular(double cost){
double x,y;

cout << "First dimension(ft): ";
cin >> x;
cout << "Second dimension(ft): ";
cin >> y;
return x*y*cost;
}
double circular(double cost){
double r;

cout << "Enter room radius(ft): ";
cin >> r;
return r*r*PI;
}

Okay, can you describe your problem? Does your compiler give you an error?

Hey Cambycis
it's working fine in my PC.
