program Specification

definition - define of what computer program expect to do should have; input, process and output flowchart (keyword)   input - enter, input   process - view, calculate, formula   output - show, display Outing Variables - identify what variable you are using create a program that would add 2 number input                        Process                                                      Output   num1                        sum= num1 + num2                                  sum  num2 Outing variables variable name                         data type                     purpose/description   num1                                        decimal                          number to be enter  num2                                        decimal                          number to be enter  sum                                          decimal                          sum of num1 and num2

control structure for for loop

# Program to find the sum of all numbers stored in a list # List of numbers numbers = [6, 5, 3] # variable to store the sum sum = 0 # iterate over the list for val in numbers: sum = sum+val # Output: The sum is 48 print("The sum is", sum)

identity operator

#identity operator a= 20 b= 20 print ("line1", "a=", a, " : ", id(a), "b=", b, ":", id(b)) if (a is b): print("line 2 - a and b have same identity") else: print ("line 2 - a and b do not have same identity") if (id(a) == id(b)): print ("line 3 - a and b have same identitiy") else: print ("line 3 - a and b do not have same identity") b= 30 print ("line 4", "a=", a, ":", id(a), "b=", b, ":", id(b)) if (a is not b): print("line 5 - a and b do not have same identity") else: print("line 5 - a and b have same identity")

membership operators

#membership operator a = 10 b = 20 list1 = [1, 2, 3, 4, 5] fi ( a in list1) : print ("line 1 - a is availabe in the givent list") else: print ("line 1 -  a is not available in the given list") if ( b not in list1): print ("line 2 -  b is not availabe in the givent list") else: print ("line 2 - b is available in the given list") c= b/a if (c in list 1) : print ("line 3 - b is availabe in the givent list") else: print ("line 3 -  b is not available in the given list #membership operator  a = 10  b = 20  list1 = [1, 2, 3, 4, 5] if ( a in list1) : print ("line 1 - a is availabe in the givent list")  else: print ("line 1 -  a is not availabe in the givent list") if ( b not in list1) :   print ("line 2 -  b is not availabe in the givent list") else: print ("line 2 - b is availabe in the givent list")  c= b/a if (c in list1) :

A data type  in programming is a classification that specifies which type of value a variable has and what type of mathematical, relational or logical operations can be applied to it without causing an error. integer is a data type that is used to classify text and an integer is a data type used to classify whole numbers.   example :  7, 12, 999 code : result:4*78 string Alphanumeric characters example:  hello world, Alice, Bob123 code:  address = "bandar seri begawan  26" Decimal  number with decimal  code: price:1.50 Boolean Representing logical values example:  true, false, yes, no  code: x=2 , y=12 float  Number with a decimal point but longer example: 3.15, 9.06, 00.13 code:  List  The list data type is an not in ordered collection type that stores unique elements. The number of elements in a list data type can vary, but no nulls are allowed. code =  list1 [1,2,3,'a','b']; CREATE TABLE employee ( name char(30),

definition of FORTRAN

FORTRAN is a general-purpose,  imperative   programming language  that is especially suited to  numeric computation  and  scientific computing . Much more into numbers what it is used FORTRAN  (formerly  FORTRAN , derived from "Formula Translation") is a general-purpose, imperative  programming language  that is especially suited to numeric computation and scientific computing. What can Fortran be used for? Yes,  FORTRAN  is  used for  large scale numerical computations. Small scale too, but it faces more competition from things like Mat lab when performance sociability is less important,  FORTRAN  isn't super famous for being intuitive and  convenient
