A If the same value as X exists in two places of the array, the 1st and N-th elements, k is set to N B If the same value as X is not in the array, k is set to N C If the same value as X exists in two places of the array, the 1st and N-th elements, k is set to D If the same value as X is not in the array, k is set to Question 13 In below definitions on the global data, which one is incorrect? A Every module in the program can access and change data B Variables which are defined within the sub module C Data that can be used by all the modules in a program D Lifetime of a global variable spans the execution of the whole program Question 14 refers to testing by a select group of potential users in the final stage of testing a program A Beta testing B Attempt at translation C Manual testing D Desk checking Question 15 Please choose correct definition of the module parameters A Reference parameters pass a copy of the value of a parameter from one module to another B Formal parameters are the one that appear when a submodule is defined C Variables and expressions that are passed to a submodule in a particular call are called formal parameters D Value parameter pass the memory address of a parameter from one module to another Question 16 The function f(x) has real arguments and returned values Consider the procedure consisting of steps ~5 as shown below using this function After starting execution and repeating the procedure a sufficient number of times, y in step stops changing Which of the following expressions holds at this point?
