Question

Consider a sequence of method invocations as follows: main calls m1, m1 calls m2, m2 calls m3 and then m2 calls m4, m3 calls m5. If m4 has just terminated, what method will resume execution?

Answer 1

M2 is the answer for the above question.

Step-by-step explanation:

• The above question states the scenario, where firstly main function calls the M1 function.
• Then M1 function calls the function M2.
• Then M2 function calls the function M3.

• Then M3 function calls the function M5.
• Then Again M2 function will resume and calls the function M4.
• Then Again M2 function will resume because when the M4 will ends it return to the statement of the M2 function from which the M4 function has been called.
• It is because when any function ends its execution it returns to that line of a statement from which it has been called. This is the property of programming language to call the function.
• So when the M4 will terminate its execution then the M2 function will resume again.
