If statements??

[Arenal]

i do not get If statements at all in C++,
i use them like it says to and i get errors
let me show you

#include <iostream>

using namespace std;

int main()
{
    if (5<4);
       Execute the next statement;
    {cout<<"HEY I UNDERSTAND IF's!!";}
    cin.get();
}

What is the (count<< part ??
other than that it seem fine, is this is , i mean there has to be an output how will you show the result.

[Arenal]

(cout is changed but i dont know what you mean by

"i mean there has to be an output how will you show the result.
"

[erhan28]

You said if 5<4. What is greater than 4? This cant be the complete code. and the output i mean, how are you going to show the "hey I know if statements". like in java its
system.out"BLAHBLAHBLAH"

[Arenal]

with iostream, it shows it on command prompt, and why would you need something greater than 4, it shouldn't show the cout b/c it's false

[erhan28]

oh ok,
you need an else or it will do nothing if the number is lees than 4.
I would show you an example but i forgot a lot about java, and java is simalar to c++.
yea try an else statement and write like "NOTTRUEBLAH" or anyother message to see if it is working.

Edit:
Some time I would script a program and keep getting errors because the program i use to type it f**ed up. SO I copy/ pasted on a new program with the exact same code and it worked, so try that too.

In Java a simple if statement would be like:

If (intNum < 4){
  //Process code here
  //intNum is less than 4
}
Else If (intNum > 6){
  //Sample Else If
  //intNum is greater than 6
}
Else{
  //Sample Else code
  //intNum is either 4, 5 or 6
}

I’m sure it’s very similar to C++.

You included a semicolon after the if statement:

if(4<5);
{
statements
}

You can't have that semicolon ( ; ) there.

A proper C++ if statement:

#include <iostream.h>

int main(void)
{
   int number=5;
   if(number<10)
   {
       cout << "The statement is true!\n";
   }
   return 0;
}

I don’t program C++, but what if you changed your if statement to this:

int main()
{
  if (5 < 4){
    //Execute the next statement;
    cout<<"HEY I UNDERSTAND IF's!!";
    cin.get();
  }
}

That’s what I was thinking, but wasn’t sure if it was (which it is) the same as in Java.

Also, for reference, a simple Google showed this:
