If variable x has value 2 and y has value 1, which values could result from the following Jack expression?

x + 3 * 4 - y

The result of the given expression is 13.

Explanation:

Here x and y are the two variable which has value 2 and 1 respectively.

x+3*4-y

Here operator * is more precedence then that + operator so

=2 + (3*4) - 1

2+12-1 now + operator is more precedence then that - operator so

= (2+12) - 1

= (14-1)

=13

Following are the program in C language

#include / / header file

int main () / / main function

{

int x=2, y=1; / / variable declaration

printf ("%d", x+3*4-1); b/ / final result

return 0;

}

Output:13
