I want to input the polynomial f from the console window,

for examples: input f=x*4-y^6+z^3

how can i do it

To be able to answer your question properly we need to know
which version of CoCoA you are using, and which interface.
Normally there should be no problem about inputting a polynomial.

John.

the version I use is cocalib0.9905,I hava installed cygwin in my computer ,which OS is window xp. I use cygwin to build the gmp and the cocoalib0.9905.

in the directory /examples/ have a sample ex-PolyInput1.C ,It have provided a method to input the polynomial f , but these inputing method is not useful .I want to have a method to inputing the polynomial f ,like the user interface of the cocoa.exe in the windows. users can input a random polynomial from the windows console,then the program comput it .

for examples,

I have a program to factorize the polynomial f ,I want to have a good user interface.when the program run .In the windows console,
it told the user ,please input the polynomial f, then the program can factorize it .

how to input the polynomial f form the windows console ,Do you have provide some function to finish it.

just liking have a program(sure ,the program not working,)
//f is a random polynomial .
program
{
std::cout<<"please input the polynomial f"<<endl;
std::cin>>f;
}

The "easy" solution is to implement the program in CoCoAL code and then use the cocoa console program. You can have it start something automatically on start, which would read user input.

If you want to make a separate console program which uses the CoCoALib instead. you will have to write a parser for polynomial input.

There is an example in examples/ex-PolyInput1.C. The input is not as elegant as you'd like: see examples/ex-PolyInput1.in
