Re: quadratic equation 9 Years Ago by Hiroshe > hey there i am trying to make quadratic equation problem solver. Good for you! Let us know if you run into any problems. Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by sanjulovers can i suggest a more simpler version ( but a bit long) version of the same function????? Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by DavidB If you are planning to submit your own code snippet, you are welcome to do so. But I would suggest you create your own thread for it, within the "Code Snippet" section. Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by sanjulovers I thought it would be easier another way. i.e using only basic elements of c++ Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by ~s.o.s~ David, it seems that your `<` and `>` have been turned into `<` and `>` respectively. Did you post it that way? If not, I'll have to ask Dani to look into it. Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by DavidB > David, it seems that your < and > have been turned into < and > respectively. Did you post it that way? If not, I'll have to ask Dani to look into it. No, I did not post it that way. If you hadn't pointed it out, I wouldn't have even noticed it. Thanks for catching it. Yes, if an admin could edit the code to put the … Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by DavidB > David, it seems that your < and > have been turned into < and > respectively.

Oops, I just noticed a few more errors: Quotation marks (") in the cout statement have been replaced by " and the newline character (\n) has been replaced by… Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by ~s.o.s~ Can you post a clean version again so that I can update the original snippet? It would be too much work editing the original snippet. Also, if you didn't post it that way, this is something for Dani to look into. Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by ~s.o.s~ Actually iamthwee brought it to our notice in [this thread he created](http://www.daniweb.com/community-center/daniweb-community-feedback/threads/456202/parsing-signs). Re: Quadratic Equation Solver - C++ Sub-routine 10 Years Ago by Nutster You are assuming all your pointers are valid. You should check for NULL pointers before assigning to pointer targets. I would recommend using references to return the results instead of pointers. Otherwise, a nice idea. Re: Quadratic Equation Solver Python, Math Module Error 12 Years Ago by Gribouillis Perhaps you're taking the square root of a negative number ? Also your formulas are false. Why not introduce a variable [icode]delta = b * b - 4 * a * c[/icode] to clean up the code ? Re: Quadratic Equation Solver Python, Math Module Error 12 Years Ago by matthewkeating What do you mean? I first find the square root and then divide by 4ac. However I will fix the negative square root.

See module cmath. Re: Quadratic Equation Solver Python, Math Module Error 11 Years Ago by nathan_czh sqrt cannot handle negative numbers, thus the error. If you get a negative number, obiously something is wrong with the inputs Re: Quadratic Equation Solver Python, Math Module Error 11 Years Ago by Gribouillis > sqrt cannot handle negative numbers, thus the error. > If you get a negative number, obiously something is wrong with the inputs This is an old thread, matthewkeating probably found the solution since he wrote this program.

Re: Simple Quadratic Equation Solver - C++ - Do You Have Any Advices Would Like to Give? 15 Years Ago by adam1122 Instead of [icode]exit(0);[/icode], consider returning a bool from your function for success or failure. Then the program can continue. I second the [icode]cin.get()[/icode] thing. It probably doesn't really matter in this case, but it's something to consider. Re: Simple Quadratic Equation Solver - C++ - Do You Have Any Advices Would Like to Give? 15 Years Ago by f.ben.isaac Ok, great... I didn't know that system("pause"); is very expensive 1.suspend your program 2.call the operating system 3. open an operating system shell (relaunches the O/S in a sub-process) 4. the O/S must now find the PAUSE command 5.allocate the memory to execute the command 6.execute the command and wait for a … Re: Simple Quadratic Equation Solver - C++ - Do You Have Any Advices Would Like to Give? 15 Years Ago by mvmalderen [QUOTE=adam1122;842916]Instead of [icode]exit(0);[/icode], consider returning a bool from your function for success or failure.
