Sheet 1

1-Write a program to find area of a square Use the equation: A = S*S


where is the side length

2-Write a program to find area and circumference of a circle Use the


equations

A=pi*R *R

C=2*pi*R

Where: pi =3.14 , R is the radius of the circle

3-Write a program to read three marks for a student and find the
average mark

4-Write a program to read the temperature in Celsius C and convert it


Fahrenheit F. Use the equation:

F = C*9/5+32

5- Write a program to read x,y,z and w and find the value of a and b
5 x y 4.5( x  2.3 y ) 2
a  and b
z 2.7 w zw

6-Wtite a program that calculates how far a satellite travels in one


rotation about the earth, given the satellite’s altitude in kilometers.
Use 12.730 km as the earth’s diameter.

7- Evaluate each of the following expressions, assuming in each case


that m has the value 25
and n has the value 7:
a) Z=m -8 – n b) Z=m + n * 3
c) Z=m%n d) Z=m%n++
e) Z=m%++n f) Z=++m – n
g) Z= ++m/2+++n/2

8- Trace the following program

#include<iostream>

using namespace std;

main ( )

{ int x=1,y=2,z=3;

z += ++x+10/2*5+y--;

cout<<” x=”<<x<<”\n y=”<<y<<”\n z=”<<z;

9-Write a program that prompts the user for the Cartesian coordinates
of two points (x1 , y1) and (x2 , y2) and display the distance between
them computed using the following formula:

𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒 = √(𝑥1 − 𝑥2 )2 + (𝑦1 − 𝑦2 )2
