What’s wrong with this please?

Question

#include <iostream>
using namespace std;

int main()
{
int a=1; {
while (a<5);
cout << "a is less then 5"; endl
}
a++;
return 0;
}

Answer 1

and you added the “greater then” ( for lack of better term) symbol before endl

Answer 2

The whole code would be this:
#include <iostream>
using namespace std;

int main()
{
int a=1;
while (a<5) {
cout << "a is less then 5" << endl;
a++;
}
return 0;
}
You probably noticed that I indented some lines; that is because it shows which lines are in functions and loops

Answer 3

but the code recognizes indentations or i dont have to?

Answer 4

You don’t have to to indentations, ut it is a good practice to. And how cout works is you seperate things you want to print by <<s. For example, to print 1 + 1 = 2 would be:
cout << "1 + 1 = " << 2;

Answer 5

Should be:
int a=1;
while (a<5) {
cout << "a is less then 5" << endl;
a++;
}

Answer 6

only one set of brackets?

Answer 7

why cant it just be
cout << “1+1=2”; ?

Answer 8

It can be like that, just I’m showing you how to print multiple things at once instead of:
cout << a;
cout << b;
Where it can be:
cout << a << b;

Answer 9

oh so that was sort of if like ‘2’ was the int i set at the begining?

Answer 10

Yes.
