Top 10 Questions for Assembler Brazer Interview

1. Explain the difference between a macro and a subroutine?

• A macro is a string of characters that is replaced by another string of characters before the assembly process begins. A subroutine is a set of instructions that can be called from multiple locations in a program.
• Macros are expanded by the preprocessor, while subroutines are executed by the CPU.
• Macros can be used to define constants, data structures, and other code elements, while subroutines can be used to perform specific tasks.
• Macros are generally more efficient than subroutines, because they are expanded at compile time, while subroutines are executed at runtime.

2. What is the difference between a label and a symbol?

subheading of the answer

• A label is a user-defined identifier that is used to mark a specific location in an assembly language program.
• A symbol is a name that is assigned to a value, such as a variable, a constant, or a subroutine.

subheading of the answer

• Labels are used to mark the beginning of instructions, data, or other code elements.
• Symbols are used to represent values that are used in the program.
• Labels are local to the assembly language program in which they are defined, while symbols can be global and can be used in multiple programs.

3. What is the purpose of the EQU directive?

• The EQU directive is used to define a constant.
• A constant is a value that cannot be changed during the execution of a program.
• Constants are often used to store values that are known at compile time, such as the size of an array or the value of a register.
• The EQU directive is similar to the #define directive in the C programming language.

4. What is the difference between the INC and DEC instructions?

• The INC instruction increments the value of a register or memory location by one.
• The DEC instruction decrements the value of a register or memory location by one.
• Both instructions can be used to add or subtract one from a value.
• The INC instruction is often used to increment a counter, while the DEC instruction is often used to decrement a counter.

5. What is the purpose of the JMP instruction?

• The JMP instruction is used to jump to a specific location in a program.
• The JMP instruction can be used to branch to a subroutine, to skip over a section of code, or to implement a loop.
• The JMP instruction is similar to the goto statement in the C programming language.

6. What is the difference between the CALL and RET instructions?

• The CALL instruction is used to call a subroutine.
• The RET instruction is used to return from a subroutine.
• The CALL instruction pushes the return address onto the stack, and then jumps to the subroutine.
• The RET instruction pops the return address from the stack, and then jumps to the return address.

7. What is the purpose of the PUSH and POP instructions?

• The PUSH instruction is used to push a value onto the stack.
• The POP instruction is used to pop a value from the stack.
• The stack is a data structure that is used to store values temporarily.
• The PUSH and POP instructions can be used to pass arguments to subroutines, to store local variables, and to implement recursion.

8. What is the difference between the ADD and SUB instructions?

• The ADD instruction is used to add two numbers.
• The SUB instruction is used to subtract two numbers.
• Both instructions can be used to perform arithmetic operations.
• The ADD instruction is often used to add two numbers together, while the SUB instruction is often used to subtract one number from another.

9. What is the purpose of the CMP instruction?

• The CMP instruction is used to compare two numbers.
• The CMP instruction sets the flags in the CPU to indicate the result of the comparison.
• The flags can be used to determine if the first number is equal to, greater than, or less than the second number.
• The CMP instruction is often used to compare two numbers before branching to a specific location in a program.

10. What is the purpose of the JZ and JNZ instructions?

• The JZ instruction is used to jump to a specific location in a program if the zero flag is set.
• The JNZ instruction is used to jump to a specific location in a program if the zero flag is not set.
• The zero flag is set when the result of a comparison is zero.
• The JZ and JNZ instructions can be used to implement conditional branching.
