An electric power substation measures voltages hourly for 72 continuous hours before they send off a report to the manager. Write a C program to generate this report that reads in 72 integer voltage readings from standard input in order to determine:

the mean voltage over the time period

the hours at which the recorded voltage varies from the mean by more than 10%

any adjacent hours when the change from one reading to the next was greater than 15% of the mean

the hours when a brownout occurred

You must store the voltage readings in an array. You may assume that all of the values inputted are legal (i.e. 0 If there are no hours that meet one of the criteria you should print the string [none] (without the quotes).

Fix the code please, so that it can print None:

#include

void printHour10Mean(int voltage[], int n, double mean, double mean10) { printf("hours that vary >= 10%% from mean: "); int i = 0;

int first = 1; for(i = 0; i

if (diff > mean10) { if (first == 1) { printf("%d", (i+1)); first = 0; } else { printf(",%d", (i+1)); }

} } printf(" "); }

void printHour15MeanNeighbour(int voltage[], int n, double mean, double mean15) { printf("hours of neighbors that vary >= 15%% of mean: "); int i = 0;

int first = 1; for(i = 1; i

if (diff > mean15) { if (first == 1) { printf("(%d,%d)", i, (i+1)); first = 0; } else { printf(",(%d,%d)", i, (i+1)); } } } printf(" "); }

void printBrownOutHour(int voltage[], int n, double mean, double brownout) { printf("hours brownout occurred: "); int i = 0;

int first = 1; for(i = 1; i

if (diff

int main() { int n = 72; int voltage[n];

printf("EGRE245 Project #5 Spring 2017 - Yaqoub Alqallaf ");

int i; double mean = 0; for (i = 0; i

double mean10 = mean*.1; double mean15 = mean*.15; double brownout = 120*(1-.108); printf("Number of voltages: 72 "); printf("Mean voltage: %.2f (10%% of mean: %.2f; 15%% of mean: %.2f) ", mean, mean10, mean15); printf("Brownout threshold: %.2f ", brownout);

printHour10Mean(voltage, n, mean, mean10); printHour15MeanNeighbour(voltage, n, mean, mean15); printBrownOutHour(voltage, n, mean, brownout); }
