The “CheckBox” control is used to set true/false or yes/no options. The user can select or deselect the Checkbox. If the user selects the Checkbox, it will return true. When the checkbox is clear, it returns a value false. The check box has 3 states. Which are, “checked”, “unchecked” and “intermediate”. In the intermediate state, the checkbox will have gray colour. The checkbox has several properties like, Appearance, “AutoCheck”, “CheckAlign”, “Checked”, “CheckState”, “Text”, “ThreeState”. Each property has its own purpose. The property “Checked” is used to get or set a value indicating whether the control has been checked or not. The checkbox has three methods which are, “OnCheckedChanged”, “OnCheckStateChanged”, and “OnClick”.

Match each of the assembler routines on the left with the equivalent C function on the right. Write the name of the label (e.g., foo) to the right of the corresponding function. Note: shrq is the logical right shift instruction, and sarq is the arithmetic right shift instruction. foo1: leaq 0(,%rdi, 8), %rax long choice1 (long x) { ret return x - 8 >8; foo3: } movq sarq %rdi, %rax $8, %rax long choice4 (long x) ret { return x*256; } foo4: long choice5 (long x) leaq -8 (%rdi), %rax { ret return x-8; } long choice6 (long x) foo5: { leaq -8 (%rdi), %rax return x+8; shrq $63, %rax } ret
