Dev-c++ Not Recognizing Cin

  • C - cin.ignore(numericlimits::max, ' '); max not recognize it I'm taking an intro to C, and I'm using VStudio 2013 on Win7. I try to avoid the wrong data input from my menus, and it's working in all of them except this one.
  • For the future, if you have some header file missing, normally the problem is that you do not have the corresponding -dev package. To try to find it, it is a good thing to install apt-file and search for it (this is an unrelated example, because iostream.h has too much hits).

Dev-c++ Not Recognizing Cin

Main Question or Discussion Point

The cin object in C is an object of class istream. It is used to accept the input from the standard input device i.e. It is associated with the standard C input stream stdin. Cin: Extracting Input from User Using Keyboard In C Extraction operator is used to accept value from the user.User can able to accept value from user and that value gets stored inside value container i.e. Syntax: Get Value from User cin variable; Explanation: Extraction Operator Include header file to.

I'm pretty sure I wrote the correct code for the quadratic formula and yet Dev-C++ continues to find a problem with my code. I will post the code I've written:
#include<iostream.hpp>
#include<math.h>
int main()
{
double root1,root2,a,b,c,root;
cout << 'Enter the coefficients a,b,c: '; ! This is the line where Dev-C++ finds an error
cin >> a >> b >> c;
root=sqrt(b*b-4.0*a*c);
root1=.5*(root-b)/a;
root2=-.5*(root-b)/a;
cout << 'The solutions are ' <<root1 << ' and ' <<root2 << 'n';
return(0);
}

I am writing a program that generates 2 random #'s then asks the user to give the product of the 2. I have everything (close to) working except the input. I even added a 'cheat' to display the answer prod and when inputting the exact same #, it is registering as incorrect.

here is the rest of the code, I just posted the relevant sections. That's why you got the errors.
