Making a table with range of values
I'm fairly new to programming, and i've run into a little wall haha. I need to make a table reporting maximum heat loss displaying height on the top, and radii on the left. both values begin with a minimum value then increase to x values depending on the user input. I need help with the looping, and where to put the loop and how? THX, all help appreciated.
Heres my code- (This code is the first part, which was to just report the heat loss)

thx alot Dr loop tutorials helped me out haha it looks like i gotta use a for loop
ur post wont let me open 1 & 2 tho, and i'm using system("pause") becasue i'm using Dev C++

hey im having trouble with the same issue
is it possible if u can post your code including the do while part

No, if you want help, post you current code here with an attempt at loops(and read the tutorials first)
@Zero
Here are the first and second links again:

They both should work now.

thx alot for helping me with this code, but for some reason the one you gave me isn't working
Typically you should ignore posts from people of post count less than 100, Not saying you should ignore ALL, just some obvious ones. Because chances are they will hinder you rather than help, that said. Could you post what you have done so far in code tags, or perhaps ask us specific questions as to what you are stuck on and we would be glad to help.
well, taking this one step at a time, im trying to display radii across the top beginning with the user initial input and then incrementing to a user defined value example:
user inputs starting value 30 for radius for a total of 10 values in increments of 1, or whatever
the for loop i tired is infinite and doesnt even increase, haha i've been at this allllllll day and have been progressing so little
heres the loop i tried:
for( height==height; n_value; height + x);
cout << height;
thats what i put after the calculations,
note: height is the inital height value, n_value is how many values of height the user wants calculated, and x is the increment number. I need radii on the top and height on the left, but i'm trying to get the loop going for the first line.
all help appreciated

well height should be initialized to 0 if you want the loop to increment, as it is at the moment an infinite loop due to the condition. For loops work like this:
for ( initialization ; condition ; increment )
1, 2 or 3 of the section can be blank, but having a condition such as n_value will not check anything.
So say n_value = 5; then all the loop is doing is checking the initialization which is fine, height = height ;
then the condition n_value which is true because it is not void. Then it is incrementing height, and checking the condition again which is true because n_value still equals 5.... infinite.
This loop will count to ten:
for ( int i = 0; i < 10; i++ )
cout << i << endl;
first pass, i is zero, the condition is true 0 is less than 10, so it prints out 0;
2nd pass, i gets incremented to 1, condition is true 1 less than 10, so it prints 1;
3rd is 2, condition true 2 less than 10, so prints 2..
and so on...
for ( initialization ; condition ; increment )

i understand the example you gave, but its just i want the first number displayed to be
user input height, and then increment to user specified number of values,
user input height, and then increment to user specified number of values,
im getting somewhere now haha
{
for (height=0.0; height>0; height+=x)
cout << height << endl;
}
now its not incrementing, but since height > 0, its not incrementing to the user specified number of values the user wants, but im getting a lil closer lol
{
for (height=0.0; height>0; height+=x)
cout << height << endl;
}
now its not incrementing, but since height > 0, its not incrementing to the user specified number of values the user wants, but im getting a lil closer lol
that's now not even going to work because the initialization will happen : height = 0;
then the condition will check: height greater than 0, which is false. thats the end.
I've been busy babysitting, but I'll try and look at the actual problem you need to solve later on when I get some time, or hopefully someone else can give you some guidance.

thx for the help, but yeah, i ran it with that infinite loop and it kept adding whatever x was, and in my input, 1,
got the same problem. my code is below. i have no idea how to create this "multiplication table" of values. i believe u are supposed to use variables for # of columns and rows.

thx alot for the error messages, as i never even thought about that, but yeah I need it to loop until a user specified number. quick question... are you making this same program too???
