Write complete C++ program that will read three integer values x, y and z from keyboard then compute the result of the following expressions.
x+'A'%3*y-z
x+'A'%3*(y-z)>(x+'A')%3*y-z
(x^2+y^2)^1/2 >10&&z++*3<15

I was thinking before that the ^ operator in the third expression was being used to represent exponientation (as in several other languages such as VB) but, on reflection, I think it's probably being used in its normal C++ sense of the 'exclusive or' operator.

So, I'd change the program to:

#include

using namespace std;

int main()
{
int x, y, z;

cout << "Enter x : ";
cin >> x;

cout << "Enter y : ";
cin >> y;

cout << "Enter z : ";
cin >> z;

int result = x + 'A' % 3 * y - z;
cout << "The value of "<< "x+'A'%3*y-z" << " is " << result << endl;

int result2 = x + 'A' % 3 * (y - z) > (x + 'A') % 3 * y - z;
cout << "The value of "<< "x+'A'%3*(y-z)>(x+'A')%3*y-z" << " is " << result2 << endl;

int result3 = (x ^ 2 + y ^ 2) ^ 1/2 > 10 && z++ * 3 < 15;
cout << "The value of "<< "(x^2+y^2)^1/2 >10&&z++*3<15" << " is " << result3;

return 0;
}

Try:

#include
#include

using namespace std;

int main()
{
int x, y, z;

cout << "Enter x : ";
cin >> x;

cout << "Enter y : ";
cin >> y;

cout << "Enter z : ";
cin >> z;

int result = x + 'A' % 3 * y - z;
cout << "The value of "<< "x+'A'%3*y-z" << " is " << result << endl;

int result2 = x + 'A' % 3 * (y - z) > (x + 'A') % 3 * y - z;
cout << "The value of "<< "x+'A'%3*(y-z)>(x+'A')%3*y-z" << " is " << result2 << endl;

int result3 = sqrt((double)(x * x + y * y)) > 10 && z++ * 3 < 15;
cout << "The value of "<< "(x^2+y^2)^1/2 >10&&z++*3<15" << " is " << result3;

return 0;
}
