Question #25886

write a program to read x and print sin x if x>0,square root x f x<0 and absolute x if x/2 is integer.
write c++ program to read two integer numbers,and read the operation to perform on these numbers
write c++ program to read 5 numbers and determine if the numbers sorted ascending or not

Expert's answer

//write a program to read x and print sin x if x > 0,

//square root x if x < 0

//and absolute x if x/2 is integer.

cout << "Input the number: x = ";

cin >> x;

if(x > 0) cout << "Sin(x) = " << sin(x) << endl;

if(x < 0) cout <<"Sqrt(x) = "<< sqrt(-x) << "i" << endl;

if((x - (int)x == 0 )&&((int)x % 2 == 0)) cout<< "fabs(x) = " << fabs(x); &

getch();
