    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.
    Free the weed!! Class B to class C is not good enough!!
    And the FAQ is here :- http://faq.cprogramming.com/cgi-bin/smartfaq.cgi

    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...........

    Angry but i can't figure out the mirror images

    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.

    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.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
