Program Listing 5.4: Using the nested if – else if statement

1 #include <iostream.h>

2 #include <stdlib.h>

3 int main()

4 {

5 int temp;

6 cout<<”\nEnter the temperature in deg C: “;

7 cin>>temp;

8 if(temp>100)

9 cout<<”\nThe water is in gas phase.\n”<<endl;

10 else if(temp <=100 && temp>0)

11 cout<<”\nThe water is in liquid phase.\n”<<endl;

12 else

13 cout<<”\nWater is in solid phase.\n”<<endl;

14 system(“pause”);

15 return 0;

16 }

Line 5: Declaration of variable temp as an integer.

Line 7: The

cin input stream requests a value from the user and stores this in

the
