Weather Calculator Program in C ++

A weather analysis program uses the following array to store the temperature for each hour of the day on each day of a week.

int temp[7][24];

Each row represents a day (0 = Sunday, 1 = Monday, etc.) and each column represent sa time (0 = midnight, 1 = 1 a.m., … , 12 = noon, 13 = 1 p.m., etc.).

- A) Write code to find Tuesday’s average temperature.
- B) Write code to find the average weekly noon temperature.

**Solution**

int main()

{

int temp[7][24];

/* tuesday = 2, noon = 12; */

cout<<“enter the two dimensional array with rows as days of the week and time as columns”;

for(int i=0;i<7;i++)

{for(int j=0;j<24;j++)

{cin>>temp[i][j];

}

} /* 00 will show position sunday and 12 noon

01 ->sunday 1 am

02->sunday 2 am

temp[1][0]->monday 1 am

temp[2][0]->tuesday 1am

temp[2][1]->tuesday 2 am

temp[2][2]->tuesday 3 am

similary we can find for all tuesdays in the array */

int tuesday_sum = 0, tuesday_averagetemp;

int noon_total=0, noon_average;

for (int i = 0; i<24; i++)

{

tuesday_sum += temp[2][i]; /* we have used 2 as it signifies tuesday */

}

tuesday_averagetemp = tuesday_total/24;

cout<<“Average temperature for tuesday is: “<<tuesday_averagetemp<<endl;

/* calculate average weekly noon temperature.Here we will fix the j variable as 12 as it detemines the time at 12 pm(noon) and we will increment i for days sunday to saturday from i=0 to i=6 */

for (int i=0; i<7; i++)

{

noon_total += temp[i][12];

}

noon_average = noon_total/7;

cout<<“” the average weekly noon temperature is “;

cout<<noon_average;
