5. Computer Programming
The history of computer programming is a steady move
away from machine-oriented views of programming
towards concepts and metaphors that more closely reflect
the way in which we ourselves understand the world
Programming has progressed through:
– machine code
– assembly language
– machine-independent programming languages
– procedures & functions
– objects

MOV R1, 34 / GET 1st VALUE
MOV R2, 36 /GET 2nd VALUE
ADD R3, R1, R2; /R3=R1+R2
END

8. Machine-Independent Programming Languages –
Fortran
This example program solves for roots of the quadratic equation,
! ax^2 +bx +c =0,for given values of a, b and c.
!
PROGRAM bisection
IMPLICIT NONE
INTEGER :: iteration
DOUBLE PRECISION :: CC, Er, xl, x0, x0_old, xr
! Set convergence criterion and guess for xl, xr.
CC = 1.d-4
xl = 8.d-1
xr = 11.d-1
! Bisection method.
Er =CC +1
iteration = 0
DO WHILE (Er > CC)
iteration = iteration + 1
! Compute x0 and the error.
x0_old = x0
x0 = (xl + xr) / 2.d0
Er = DABS((x0 - x0_old)/x0)*100.d0
WRITE (*,10) iteration, x0_old, x0, Er
10 FORMAT (1X,I4,3(2X,E10.4))

9. Procedures & Functions – Pascal
program ValueArg(output);
{Shows how to arrange for a procedure to have arguments.}
procedure PrintInitials(First, Last : char);
{Within this procedure, the names First and Last represent the argument
values. We’ll call write to print them.}
begin
write(‘My initials are: ’);
write(First);
writeln(Last)
end; {PrintInitials}
begin
PrintInitials (‘D’, ‘C’); {Any two characters can be arguments.}
PrintInitials (‘Q’, ‘T’); {Like strings, characters are quoted.}
PrintInitials (‘&’, ‘#’)
end. {ValueArg}

class Time {
private int hour, minute;
public Time (int h, int m) {
hour = h;
minute = m;
}
public void addMinutes (int m) {
int totalMinutes =
((60*hour) + minute + m) % (24*60);
if (totalMinutes<0)
totalMinutes = totalMinutes + (24*60);
hour = totalMinutes / 60;
minute = totalMinutes % 60;

//This application program prints Welcome
//to Java!
package chapter1;
public class Welcome {
public static void main(String[] args) {
System.out.println("Welcome to Java!");
}
