for statements

I know I don't need this many for statement but I can't figure out how they should be combined.


main()

{

cout<<"\n\n\n";
cout<< "*";
cout<<"\n";

for (int s1=0; s1<2; ++s1)
cout<<"*";
cout<<"\n";

for (int s2=0; s2<3; ++s2)
cout<<"*";
cout<<"\n";

for (int s3=0; s3<4; ++s3)
cout<<"*";
cout<<"\n";

for (int s4=0; s4<5; ++s4)
cout<<"*";
cout<<"\n";

for (int s5=0; s5<6; ++s5)
cout<<"*";
cout<<"\n";

return 0;

You only need 2 loops. They should be nested 1 inside the other. 1 controls printing of '*' and the other controls printing of '\n'.
See if you can work it out.

Your code should be "s5++", not "++s5"

Thought you should know.

why? it doesn't make a difference in this case. just a loop update, and you can increment either it way you want, whether it be post- or pre- increment.

nested for loop...have the outer loop control the \n, and the inner control the *

here's an example of what you could do (comin' up with this off the top of my head)

Code:

---

int main()
{
        cout<<"\n\n\n";
        for(int a=1;a<=6;a++)
        {
                for(int b=0;b<a;b++)
                        cout<< '*';
                cout<< endl;
        }
        return 0;
}

that theoretically works (i'm at school right now, so i don't have a compiler handy)

hope that helps, and i'm assuming this is for an assignment or something, because i had a problem somewhat like this when i was in programming...........

1st what is a signature virus---there's one attached to one of the replies

sometimes i think it's where i place my parenthese.

should i use a space and a * loop. when i do that it prints continous stars

{

cout<<"\n\n\n";
{
for (int r=1; r<=11; ++r)

{
for (int c=1; c<=r; ++c)
cout<<"*";
cout<<"\n";
}
}

cout <<"\n\n";
{ for (int r2=1; r2<=11; ++r2)

{
for (int c2=11;c2>=r2;--c2)
cout<<"*";
cout<<"\n";
}
}
cout<<"\n\n";
{for (int r3=1; r3<=11; ++r3)//loop for rows

{for (int sp=1; sp<=1; ++sp)//loop for spaces
cout <<" ";
{for (int c3=10;c3>=r3;--c3)// loop for stars
cout<<"*";
cout<<"\n";
}
}
}
return 0;
}

Its not a real virus. Not quite sure what the purpose of it is though.

it's just kinda funny to see how many people will add it to theirs :)

What would be a better invention, is a code tag virus. Lyanette, please make use of the tags, your code is too hard to read without them.
