4. Develop the following template into an embedded C program. / Global variables here- avoid declaring too many globals unnecessarily as it is not considered a good programming practice. ' nt creditRatingAlice 750; Il 0 represents "defaulted" and 1 represents paid" for the payment history int monthlyPaymentHistoryAlice 24] 1,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,0,1,1,1,1,1,0,1] void main (void) Imain), while looping endlessly, sets a global flag creditStatus to the value returned by the function II rewardsOrAlarm). Function called when Alice makes a monthly payment or defaults on the monthly payment. Returns nothing, updates global variable creditRatingAlice. 7 void updateCrediRatingAlice (int opcode,0 if default, 1 if paid */) { Il each monthly payment increments rating by 10 points all the way up to 800 Il every default decrements rating by 10 points down to 700 Function that raises an alarm when Alice's rating is 700 for 2 consecutive months, Returns 0 if alarm, 1 if reward. or rewards her if she has maintained a rating of 800 for 2 consecutive months. *Reads montlyPaymentHistoryAlice for input. Page 2 of 4 int rewardsOrAlarm 0 Il Read next value in monthlyPaymentHistoryAlice. Note that this function needs to keep track of the Il last array element accessed so that when it reaches the last it can rewind to the first in a round Il robin fashion to read a value from the monthlyPaymentHistoryAlice array forever. Il Pass the read value in monthlyPaymentHistoryAlice to function updateCreditRatingAlice int x) l/ Return reward/alarm value
