Question

Read the following code and determine what is the decimal values of num1 and num2 after execution of the code.

short num1 = 25, num2 = 0x7A, temp ;

short *x; temp = num2; // num1 = ? num2 = ?

x = &num1; // num1 = ? num2 = ?

num2 = num1; // num1 = ? num2 = ?

*x = temp; // num1 = ? num2 = ?

Answer 1

short num1 = 25, num2 = 0x7A, temp;
short *x; temp = num2; // num1 = 25 num2 = 0x7A
x = &num1; // num1 = 25 num2 = 0x7A
num2 = num1; // num1 = 25 num2 = 25
*x = temp; // num1 = 0x7A num2 = 25
