Question 1

The following statements exit a macro if the count argument is blank:&#10;IFB &#10;EXITM&#10;ENDIF

Accepted Answer

The IFB macro condition checks if the count argument is blank or not. If it is blank, the EXITM macro instruction is executed and the macro is exited. Therefore, the statement exits the macro if the count argument is blank.

Question 2

The following statements permits assembly if the symbol Win32 has been defined:&#10; IFDEF Win32

Accepted Answer

This is because the statements inside the IFDEF block will only be assembled if the symbol Win32 has been previously defined using a #define directive. If Win32 has not been defined, the assembler will skip over these statements.

Question 3

The IFNDIF directive permits assembly if two arguments are equal.

Accepted Answer

The IFNDEF directive is used to assemble a block of code if a specified identifier has not been defined, not for checking the equality of two arguments.

Question 4

A structure variable cannot be declared inside another structure.

Accepted Answer

A structure variable can indeed be declared inside another structure, allowing for nested or complex data structures. This is a common practice in programming to create more organized and hierarchical data models.

Question 5

The following statements create five uninitialized DWORD variables in which each variable name is a member of the following list: monday,tuesday,wednesday,thursday,friday:
FOR varName,
DWORD varName <>
ENDM

Accepted Answer

The statements create uninitialized DWORD variables with names monday, tuesday, wednesday, thursday and friday using a macro in which the variable names are passed as parameters.

Question 6

The following macro moves any 32-bit memory operand to any other 32-bit memory operand:
mMove32 MACRO destination,source
push eax
mov eax,source
mov destination,eax
pop eax
ENDM

Accepted Answer

The macro uses the EAX register to temporarily hold the value of the source operand before moving it to the destination operand. This can work for any 32-bit memory operands.

Question 7

All fields in a UNION begin at the same offset.

Accepted Answer

In a union, each field shares the same memory space, so they all begin at the same offset.

Question 8

An array can be declared as a structure member.

Accepted Answer

Yes, an array can be declared as a structure member. This allows for organizing related data into a single structure.

Question 9

When a macro is invoked,the CALL instruction executes if the macro uses the ASPROC operator.

Accepted Answer

The ASPROC operator in macro definitions is used to indicate that the macro should be treated as a procedure call, but it does not directly involve the CALL instruction. The macro expansion mechanism handles the invocation, not the CALL instruction typically used for calling procedures or functions in assembly or high-level languages.

Question 10

When defining a structure variable,you can specify default values for zero or more structure fields.

Accepted Answer

When defining a structure variable in C++, you can specify default values for zero or more structure fields. This can be done using the following syntax:

struct myStruct {
   int field1 = defaultValue1;
   float field2 = defaultValue2;
   char field3 = defaultValue3;
};

Here, you can specify the default values for each field when the struct is defined. If no value is specified, then the default value for that data type will be used.
