Write a
C++ program that stores the number 105.62 in the variable firstnum,
89.352 in the variable secnum, and 98.67 in the variable thirdnum.
Have your program calculate the total of the three numbers and their average.
The total should be stored in the variable total and the average in the
variable average. Use the cout object to display the total and
the average.
STEP#1 Start
STEP#2 Declare
the variable Firstnum, Secnum, Thirdnum, Total,
Average
STEP#3 Assign
value 105.62 to Firstnum
STEP#4 Assign
value 89.352 to Secnum
STEP#5 Assign
value 98.67 to Thirdnum
STEP#6 Calculate
Total and Average
STEP#7 Total=
(Firstnum+Secnum+Thirdnum)
STEP#8 Average=
(Total/3)
STEP#9 Display
the Total
STEP#10 Display
the Average
STEP#11 End
#include
<iostream>
using
namespace std;
int main()
{
float radius,area,circum;
radius=3.5;
area=3.14*(radius*radius);
circum=2*3.14*(radius);
cout<<area<<"\n";
cout<<circum<<"\n";
return 0;
}
