WAP to input the number of units of electricity consumed, calculate and print out the charges.

The Electricity board charges according to the following rates:

For the first 100 units – 40 P per unit ( P -> Paise)
For the next 200 units – 50 P per unit
Beyond 300 units – 60 P per unit
All users are charged meter charge also which is Rs. 50/-

void main()
{
int unit;
float charge;
cout << “\n Enter the no. of units , Electricity Consumed :”;
cin >> unit;
if (unit <= 100 )
charge = 50.0 + 0.4 * unit;
else if(unit<=300)
charge = 50.0 +4.0 * 100 + 0.5 * (unit – 100);
else
charge = 50.0 + 4.0 *100 + 0.5 * 200 + 0.6 *( unit – 300) ;
cout << “n The charges is Rs. “ << charge;
getch();

WAP to input acceleration (cm/sec*sec) and time . calculate the final velocity of an object , that is initially static.

#include<iostream.h>
#include<conio.h>



void main()
{
int ac, t, v;


cout<< "Enter acceleration in cm per second square ";
cin >> ac;
cout<< " Enter time to travarse ";
cin >> t;


v = ac * t; 
// formula of final vel = initial vel + acceleration * time (initial vel = 0)


cout << " Final velocity = " << v << " cm / sec*sec ";


getch();
}
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do it blows your whole leg off.
