Exercise 5
Program that calculates the average of 5 numbers that can be input by user.
#include iostream.h
main()
{
int num1, num2, num3, num4, num5, average;
cout<<"enter number 1";
cin>>num1;
cout<<"enter number 2";
cin>>num2;
cout<<"enter number 3";
cin>>num3;
cout<<"enter number 4";
cin>>num4;
cout<<"enter number 5";
cin>>num5;
average=(num1+num2+num3+num4+num5)/5;
cout<<"average for five number is=" , average;
}
Exercise 6
Program that will calculate the area of rectangular, triangle and circle.
#include iostream.h
main()
{
double area_rect , area_triangle, area_circle, base , height, width, radius;
const double =3.14;
cout<<"Calculate area of rectangular.";
cout<<"Enter height=";
cin>>height;
cout<<"Enter width";
cin>>width;
area_rect=height * width;
cout<<"area of rectangular=", area_rect;
cout<<"Calculate area of triangle.";
cout<<"Enter base=";
cin>>base;
cout<<"Enter height";
cin>>height;
area_triangle= 1/2 * base * height ;
cout<<"area of triangle=", area_triangle;
cout<<"Calculate area of circle.";
cout<<"Enter radius=";
cin>>radius;
area_circle= 3.14;
cout<<"area of circle=", area_circle;
