Triangle.

Nov 5th, 2009

I have to print a triangle in C++ where the length is double the height and base of the triangle it is to be isosceles

this is my Isosceles code. how do I change the length base and width so that the length is double. We are only allowed to use stuff up to for loops nothing too fancy. Thank you!

What you have there is simply a hard coded triangle. You need to write the code to setup the triangle's height and width. Give it a shot and post your problem once you try it.

I know i have to declare the Variables height base and length

int i, base, hieght, length 
for (i = 0; i< 1; ++1) {
printf("*\n"
"hieght= 10"
"base= 10"
"length= 20"}
int i, base, hieght, length 
for (i = 0; i< 1; ++1) {
printf("*\n"
"hieght= 10"
"base= 10"
"length= 20"}

Here you have declared the variables, but then output just constant expressions...

I'd suggest googling for "basic c++" and trying some of the simple examples you find until you get familiar with the basics. Then you can try to write this triangle program as a demonstration to yourself that you've learned something!

Well i know how to do basic programming, I am in a class. I just do not know what to do next. Hence why I am asking on the forum. They are always my last resort. That is exactly what I do, I do basic programs first and then I elaborate on those. But I am entirely lost on where to go from my basic triangle program.
