I am working on this problem for my one of my classes and can't seem to get it to work. Any suggestions?

We use Gnu 2.1.73 and SciTE





fprintf('\nThis program solves the equation ax^2+bx+c=0 for x.\n\n');


a = input('Enter the coefficient a: ');


b = input('Enter the coefficient b: ');


c = input('Enter the coefficient c: ');





if(a==b==c==0)


fprintf('all possible solutions\n');


elseif(a==b==0)


fprintf('no possible solutions\n');


elseif(b^2-4*a*c %26lt; 0)


fprintf('no real solutions\n');


elseif(b^2-4*a*c ==0)


x = -b/(2*a)


fprintf('%3.2f.\n', x);


elseif(b^2-4*a*c %26gt; 0)


x1 = (-b+(((b^2)-4*a*c)^(1/2)))/(2*a)


x2 = (-b-(((b^2-4*a*c)^(1/2))))/(2*a)


fprintf('The quadratic equation has two solutions:');


disp([x1 x2]);


end;

Hey,





I have a few suggestions. I am not familiar to SciTE, but it resembles Matlab which I've worked with.





Try setting a variable for your equation for the elseif comparisons.





ie. d = ax^2+bx+c





Then use elseif(d %26lt; 0);





You could also use if(d==0)


This would correct any issues dealing with the variables. In Matlab they have this horrible "dot notation". Where when a defined variable is altered you need to add a period/dot before it. Make sure there isn't anything like that required.





Also make sure you are using your if arguments correctly. Does the syntax support "and/or" arguments such as %26amp;%26amp; / || ?
Reply:...dunno what Gnu 1.1.73 and SciTE are, but your solution equations seem to be unfinished.
Reply:Try again.
Reply:I don't know what is "Gnu 2.1.73 and SciTE" but you can check these items:


1- when (a=b=c=0) is true, then (a=b=0) will be true too. hence you will have both "all possible solutions" and "'no possible solutions" in output.


2- can you use an empty line?(as you have used in 5th line)


3- is it possible to use more than one "elseif" for each "if"?


4- don't you need any other command when you use "if"? (for instance an "endif" command)
