hi this is Fatima..!! i have started C++ programming few days back..!!

i am given an assignment fer homewrk.In the prob i have to take the sqr root but i dun knw how to take square root.

the code is

in the last part if b^2-4ac is greater than and equal to zero then i have to take square root of it..and display the roots but i dun knw how to..!!Code:#include<iostream.h> #include<conio.h> void main() { clrscr(); int roots1,roots,a,b,c; cout<<"Enter value of a="; cin>>a; cout<<"Enter value of b="; cin>>b; cout<<"Enter value of c="; cin>>c; if (b*b- 4*a*c==0) { cout<<"Roots are single,equal"; } else if (b*b-4*a*c>0) { cout<<"Equation has two real roots"; } else if (b*b-4*a*c<0) { cout<<"Equation has two complex roots"; } else if (b*b-4*a*c>=0) { roots=-b+sqrt(b*b-4*a*c)/2*a; roots1=-b-sqrt(b*b-4*a*c)/2*a; cout<<"The roots are"<<roots<<roots1<<endl; } getch(); }
