Write and test a program that solves quadratic equations. A quadratic equation is an equation of the form ax2+ bx + c =0 ,where a,b and c are given coefficient and x is the unknown The coefficients are real number inputs ,so they should be declared of type float or double Since quadratic equations typically have two solutions ,use x1 and x2 for the solutions to be output These should be declared of type double to avoid inaccuracies from round-off error

protected access specifier allows access to the super class(i.e., the class which is declared as protected) and provides access only to the first level of inheritance(i.e., the base class which is first derived from the protected super class). isn't it?..

The code shown below in the description runs here when I try it, but when I wrote it on code blocks it gave me 5 errors.. 1. expected imitializer before '<' token. (line 19). 2. reference to 'pair' is ambiguous. (line 26). 3. expected primary-expression before double. (line 26). 4. expected ';' before 'double'. (line 26). 5. 'obj' was not declared in this scope. (line 27). Any help please?

In the short code below, I declared an array of five elements. But I'm getting confused on how to use it in a while loop. My main question is , if the user inputs a userchoice1 value that is less than 1, I want the code to keep looping until the user inputs a number that is not less than 1. But I don't know if the 7th line (userchoice1 [x]++) shows the right way to loop it.
