Answer to Question #7268 in C++ for Haniff Halmi

Question #7268

Write a program that will read daily temperature reading for the month of January 2012. Your program should contain the following functions:

(a) main() function contains instructions of reading input needed and print all the related information.
(b) NORMAL() function calculates the number of normal days (temperature between 60F and 84F)
(c) AVERAGE() function calculates the average temperature in January 2012.
(d) DAYS() function calculates the number of days which has temperature more than the average.

Expert's answer

#include <iostream>
using namespace std;

const int
n=31;

int NORMAL(int * deg){
int res = 0;
for( int i=0; i<n;
i++){
if(deg[i]>=64 && deg[i]<=80)
res++;
}
return
res;
}

double AVERAGE(int * deg){
double res = 0;
for( int i=0;
i<n; i++){
res +=deg[i];
}
return res/n;
}

int DAYS(int *
deg){
int res = 0;
double e = AVERAGE(deg);
for( int i=0; i<n;
i++){
if(deg[i] > e)
res++;
}
return res;
}

int
main(){
int * temp = new int [n];
cout<<"Input 31 value of
tempetarute in January 2012\n";
for( int i=0; i<n; i++
){
cout<<i+1<<":
";
cin>>temp[i];
}
cout<<"The number of normal days:
"<<NORMAL(temp)<<endl;
cout<<"The average temperature
value: "<<AVERAGE(temp)<<endl;
cout<<"The number of days
which has temperature more than the average:
"<<DAYS(temp)<<endl;
system("pause");
return 0;
}
