Look at the following statement While (x++ < 10) which operator is used first?

<

#include <iostream> using namespace std; void largest(int, int, int, int &); void larger (int, int, int &); int main(int argc, const char * argv[]) { int largest_Number; int num1; int num2; int num3; cout <<"Enter a number; "; cin >> num1; cout <<"Enter a number; "; cin >> num2; cout <<"Enter a number; "; cin >> num3; largest(num1, num2, num3, largest_Number); cout << "The largest number is: "<< largest_Number; return 0: } void larger(int X, int Y, int & E) { if(X>Y) { ____________ } else { ____________ } } void largest(int A, int B, int C, int & D) { larger(A, B, D); int largest1=D; larger(largest1, C, D); }

E=X; E=Y;

Which of the following statements about global variables is true

subscript numbering in C++

begins with 0

This statement causes a loop to terminate early

prefix

This operator increments the value of its operand, then uses the value in context.

prefix increment

linux command pwd means
