Given Triangle struct (in files Triangle.h and Triangle.c), complete main() to read and set the base and height data members of triangle1 and of triangle2, determine which triangle's area is smaller, and output that triangle's info, making use of the relevant Triangle functions. Ex: If the input is: 3.0 4.0 4.0 5.0 where 3.0 is triangle1's base, 4.0 is triangle1's height, 4.0 is triangle2's base, and 5.0 is triangle2's height, the output is: Triangle with smaller area: Base: 3.00 Height: 4.00 Area: 6.00 412800.2778464.gx320/7 LAB ACTIVITY 1 #include 2 #include "Triangle.h" 3 4 void setBase (Triangle *triangle, double base) { 5 triangle->base = base; 6} 7 8 void setHeight (Triangle triangle, double height) { 9 triangle->height = height; 10} 11 12 void calculateArea(Triangle *triangle) { 13 14} 9.11.1: LAB: Triangle area comparison 24 25 26 27 28 29 15 16 void printTriangle(Triangle triangle) { 17 18 19 20 } 30 31 32 21 22 main() { 23 33 34 35 36 37 38 39 40 41 triangle->area = 0.5 *…

1. Write an application named GoToo Far in which you declare an array of five integers and store five values in the array. Write a try block in which you loop to display each successive element of the array, increasing a subscript by 1 on each pass through the loop. Create a catch block that catches the eventual ArrayIndexOutOfBoundsException and displays the message, "Now you've gone too far". Save the file as GoTooFar.java.
Class name: SURNAME_MATRIX Data fields: two(2) q xr arrays where: q = no. of characters of your first name. If q <= 5 then q = q * 2. r= no. characters of your surname. if r<= 5 then r=r*2. Methods: Constructor: initialize two(2) arrays. Value of each element = no. of characters of your fullname * 2.5. fillA1() - populate 2d-Array1 with random numbers. (200 max). seed - default fillA2() - populate 2d-Array2 with random numbers. (5000 max). seed - default addSubA1A2(int flag) - add or subtract the two matrices and display the resultant matrix (size is q xralso). (note: invoke first fillA1() and fillA2()) if flag is nonzero add matrices else subtract matrices. e.g. addSubA1A2(3) <-- add arrays, addSubA1A2(0) <-- subtract arrays toString() - displays the current date once and your fullname k times where kis a random number < 8. Filename: SURNAME_SSE2.java In main(): Create two(2) objects using array of objects and use ALL the methods for each object.

Description:Create JFrame application called Dictionary.Set up three one-dimensional arrays to contain the equivalent English andother-language-of-your-choice nouns, and the images of those objects.Typing a word in one of the languages and hitting the appropriate buttonshould produce the translation and display the picture of that object. Makesure you check to see whether the word is in the dictionary. If it is not,display a message "Word is not found".Three arrays will be of equal length (array_length).The program should work for different array_length values. Test andupload for array_length = 10.Requirements: This project requires typing a word in one of the languages. So, theprogram should be interactive. The word search should be case-insensitive. Three arrays must be declared: two String arrays for words in twolanguages and the third array for pictures files names. List of words in dictionary should be displayed for user With arrays, use for or enhanced for loop. Enhanced for…
Assume that the value $utype='doctor'; is stored in the $_SESSION array using the index type. Which of the following statements will display the image heart.jpg for doctor users. • session_start(); • if(isset($_SESSION['type']) { if($_SESSION['type']=='doctor") echo ""; } O • session_start(): $_SESSION['type']='doctor'; • echo ""; O echo ""; O if(isset($_SESSION['type']) echo "";
Array can store values of different datatypes. Select one: O True False
