The following code is correct. Perform a program trace of the following code and show what the output will be. (Note: For the program trace and the output, write your answer next to each line in the code as shown below): #include using namespace std; void boo(); int var 0; void boo() ( var++; var } int main() { int x, a; double f; x=1; x++; ++x; x x x f a = x++; f = x / a; var++; boo(); var cout < < "x is " < < x < < endl; cout < < "a is " < < a < < endl; cout < < "f is " < < f < < endl; cout < < "var is " < < var < < endl; output output- output = output =
