First ever for loop

[ryanvkeller]

I've never used a for loop before but im trying to use a for loop now instead of a while loop to print the numbers from n1 to n2 but when i set n1 to 5 and n2 to 10 it outputs 11 not al the numbers in between....


cout<<" Enter a number to start the count at. \n";
cin>>n1;
cout<<"Now enter a number to stop the count at. \n";
cin>>n2;

for (i=n1; i<=n2; i++);
cout<<i<<" ";

The semicolon doesn't belong there.

[ryanvkeller]

which one?

After the for loop.

Like if statements, you don't want ; after them.

[Athar]

Let's rephrase that to a question: according to you, how is the compiler supposed to know that cout<<i<<" "; is supposed to be part of the for loop instead of a statement that is executed after the for loop?

Oh ok i see! Thanks fire draco and athar

If we use your code as an example this should be the syntax

cout<<" Enter a number to start the count at. \n";
cin>>n1;
cout<<"Now enter a number to stop the count at. \n";
cin>>n2;

for(int i=n1; i<=n2, i++)
{
    cout << i << " "; 
}

Never put a semi colon after the closing curly brace or the initialising condition parentheses.
