A program contains a global 1D array Number consisting of 20 elements of type REAL A procedure Store () will input a sequence of up to 20 real values, one value at a time. These values will be assigned to elements of the array using four steps: Step 1: store the first value in the sequence in the first element of the array Step 2: check each subsequent value input. If this value is larger than the previous value input, then assign the value to the next array element, otherwise go to step 4 Step 3: repeat from step 2 unless the array is full Step 4: output the count of the number of values stored in the array together with a suitable message.

1. (a)Complete the pseudocode for Store() All variables used in the algorithm must be declared. PROCEDURE Store() ENDPROCEDURE[6]
2. (b)(i)The requirements of the program change: • the number of values in the sequence is unknown, but may be higher than 20 • the values will need to be accessed by another program as data. The data will be stored in a text file instead of an array. Give two benefits of using a text file instead of an array.[2]
3. (b)(ii)State any change that will need to be made before each value is written to the file.[1]
