Challenge yourself with questions covering:
- Instruction execution stages
- Constant folding and dead code
- Loop-invariant code
- Inline fun
ctions and memory management

Substitution of values for names whose values are constant, is done in
Local optimization
Loop optimization
Constant folding
None
Dead code plays no role in any program operation and therefore it can simply be eliminated.
TRUE
False
Can be true or false
Can't Say
A fragment of code that resides in the loop and computes the same value at each iteration is called a?
Induction analysis
Strength reduction
Loop-invariant code
None of the above
In compiler terminology reduction in strength means
Replacing run time computation by compile time computation
Removing loop invariant computation
Removing common subexpressions
Replacing a costly operation by a relatively cheaper one
Name the function whose definition can be substituted at a place where its function call is made
Friends function
Inline function
Volatile function
External function
What is the effect of the Inline function on executable size?
No effect on executable size
Decreases the executable size
Increases the executable size
None
What is the effect of the Inline function on memory?
Can cause thrashing
Can cause more number of page faults
Both
None
When the inline function is resolved/expanded?
