PPT-Lecture 6 Arrays and Vectors

Sampath Jayarathna Cal Poly Pomona Based on slides created by Bjarne Stroustrup amp Tony Gaddis CS 128 Introduction to C 1 Arrays Hold Multiple Values Array variable that can store multiple values of the same type. How are PCR Arrays Utilized The RT57522 Profiler PCR Arrays have been increasingly used in research on cancer immunology stem cells toxicology biomarker discovery and validation and phenotypic analysis of cells and transgenic animals Why PCR Arrays Rectangular & Jagged. Plus: More 1D traversal. Array. . Recall. Creating a 2D array of doubles:. double[][] grid = new double[3][4]; . 3 rows: indices 0 to 2, 4 columns: indices 0 to 3. grid. : reference to entire array. Dr. Jose Annunziato. Arrays. Up . to this . point we have been working with individual primitive data types. Arrays allow working with multiple instances of data of the same type. Arrays contain (or refer) to several pieces data stored in contiguous memory spaces. A.S. 1.3.1 – 1.3.4. Scalar Quantities. Those values, measured or coefficients, that are complete when reported with only a magnitude. Examples:. . the table is 2.5 m long. . He ran the 100. m race in 12.65 s.. Which of the following is the odd one out?. Mass. Speed. Force. Temperature. Distance. Elephant. Which of the following is the odd one out?. Mass. Speed. Force. Temperature. Distance. Elephant. Scalars. A . scalar. quantity . can be described by a . single number. , . with some meaningful . unit. 4 oranges. 20 miles. 5 miles/hour. 10 Joules of energy. 9 Volts . Vectors and scalars. A . scalar. quantity . We will often need to store collections of information. a list of names to sort. a list of values to compute averages, standard deviation, . etc. a group of GUI components. Java provides different types of . GENETIC. . ENGINEERING. Genetic engineering is the manipulation of genetic materials which can be introduced in the host organisms and thus change the phenotype of the host organism.. Matrices. Definition: A matrix is a rectangular array of numbers or symbolic elements. In many applications, the rows of a matrix will represent individuals cases (people, items, plants, animals,...) and columns will represent attributes or characteristics. What is an Array?. Array is a data structure that . holds . a . collection. of . data of the . same . type. . Java . treats . arrays as . objects. . This means array variables are . reference . variables, .

Lecture Set 9 Arrays, Collections and Repetition Part C - Random Numbers Rectangular and Jagged arrays 1/4/2016 10:04 PM Objectives Understand the concept of random numbers and how to generate random numbers John Keyser’s. Modification of Slides by. Bjarne. . Stroustrup. . www.stroustrup.com/Programming. Abstract. arrays, pointers, copy semantics, elements access, references. Next lecture: parameterization of a type with a type (templates), and range checking (exceptions).. Accident Problem. Each year the Department of Traffic Accidents receives accident count reports from a number of cities and towns across the country. Given details of ‘n’ days, develop an algorithm and write a program to determine the average number of accidents and for each day, print the difference between the number of accidents on that day and average. For example, if the number of accidents is 5 and the values are 10, 12, 15, 13, 5 then average is 11 and the difference of values are 1, 1, 4, 2, 6.
