CS201 VU Assignment No. 2 Spring 2012 Solution

Problem Statement:    Temperature Calculation system    

Write a program that displays average, highest and lowest temperatures.

Detailed Description:

  • The program will take temperature readings as input from user for specified number of consecutive days.
  • Program will store these temperature values into an array.
  • Then it will pass this array to three different functions.
  • One function will return highest temperature, one will return lowest temperature and third one will return average temperature.
  • All these functions will be called inside main() function where these temperature results will be displayed to the user.Enter the number of consecutive days to read their temperature : 5Enter temperature for day 1: 50Enter temperature for day 2: 80

    Enter temperature for day 3: 30

    Enter temperature for day 4: 92

    Enter temperature for day 5: 47

    The average temperature is 59.80

    The highest temperature is 92.00 The lowest temperature is 30.00

    NOTE:

    The array containing temperature values must be passed to three different functions to return average, highest and lowest temperatures. Marks will be deducted if assignment is solved with some other technique.

Solution:

#include <cstdlib>
#include <iostream>

void high_Tenp(int [],int);

void low_Tenp(int []);

void Average_Tenp(int [],int);

using namespace std;

int main(int argc, char *argv[])
{

cout<<"tt***********************************"<<endl
<<"tt TEMPRATURE CALCULATION SYSTEM "<<endl
<<"tt***********************************"<<endl<<endl;
int n;

cout<<"Enter the number of consecutive days to read their temperature : ";

cin>>n;

int x[n];

int i, j, tmp;

for(i=0;i<n;i++)
{

cout<<endl<<"Enter temperature for day "<<i+1<<" : ";

cin>>x[i];

}

for(i=0; i<n; i++)
{

for(j=0; j<n-1; j++)
{

if (x[j] > x[j+1])
{

tmp = x[j];

x[j] = x[j+1];

x[j+1] = tmp;

}

}

}

Average_Tenp(x,n);

high_Tenp(x,n);

low_Tenp(x);

system("pause");

}

void high_Tenp(int a[],int arraysize)
{
cout<<"The Higest Temprature is : "<<a[arraysize-1]<<endl;
}

void low_Tenp(int a[])
{
int b=0;
cout<<"The Lowest Temprature is : "<<a[b]<<endl;
}

void Average_Tenp(int a[],int arraysize)
{
int i;

double c=0;

for ( i = 0 ; i < arraysize ; i ++)
{
c=c+a[i];
}
c=c/i;
cout<<endl<<"The Average Temprature is : "<<c<<endl;
}

void swap(int *x, int *y) //function using pointers to interchange the values

{

int tmp;

if(*x > *y)

{

tmp = *x;

*x = *y;

*y = tmp;

}

}
