write a complete statement write the declaration of P (a pointer to integer) * write the declaration of fin (input file stream that opens the file "mydata.txt") * write the declaration statement for funx (a float function with two integer arguments x and y both passed by reference) * read a character from the file fin and assign it to the variable T. * declare a pointer with the name Pnt1 to that points to the integer variable X. * close the file fin * Make the value pointed to by the pointer Ptr zero. *

1. Declare a file pointer called input. Open a file called location.txt for reading using this pointer. 2. If the file is not available, display “File does not exist. ". 3. The content of the text file location.txt is as shown below. It includes the location, latitude and longitude values. FILE location.txt CONTENTS UTM 1.5523763 103.63322 KLCC 3.153889 101.71333 UM 3.1185 101.665 UMS 6.0367 116.1186 UNIMAS 1.465174 110.4270601 Ask the user to enter a location. Check if the user's location can be found in the text file. If found, display the location, latitude and longitude as shown below. SAMPLE OUTPUT Enter a location: UM : UM : 3.1185 : 101.6650 Location Latitude Longitude Otherwise display “Sorry, location could not be found". SAMPLE OUTPUT Enter a location : MMU Sorry, location could not be found

1 Goals Use C++ to read data from a text file and create an array of numbers. Use the C++ 'fstream' library functions to open, read and close a text file. You can use the C++ 'iomanip' library to format your output and manage whitespace on your input. Graduate students must create and write the data to a new text file. 2 Your assignment is to create a program that does the following: a. You will need to create a new file (you can do this in the file system – make it plain text) and call it mydata.txt. b. Put a column of numbers in the text file to read later. Pay attention to type – make them all have decimal points. In repl.it, use the numbers in my file. c. Based on the examples in the slides (L3) and the textbook, write a C++ program, include 'iostream' and 'fstream'. You might need 'iomanip'. d. Your program should read the numbers from the file into an array and print the array to the console in reverse order using a for loop. e. Graduate Students must also print the output to a…

Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only.   Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum   Example   data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1   Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible   Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.

1. Outputting Type Sizes to a File (50): Write a C program that uses the sizeof operator to determine the sizes in bytes of the various data types on your computer system. Write the results to the file "datasize. dat" so you may print the results later. The format for the results in the file should be as follows: Data type Size char 1 unsigned char short int 2 unsigned short int int 2 unsigned int long int unsigned long int float 4 4 4 double 8 long double 16 (The type sizes on your computer might be different from those shown in the sample output)

Function ____________opens a file.

Write a program in C++ to do the following: 2. Create an array to hold up to 20 integers. 3. Create a data file or download attached text file (twenty_numbers.txt) thatcontains UP TO 20 integers.4. Request the input and output file names from the user. Open the filesbeing sure to check the file state.5. Request from the user HOW MANY numbers to read from the data file,up to twenty. Request the number until the user enters 20 or less, but not lessthan 0. The user enters the number of integers to read. The integers are storedin the file and are to be read from the file.6. Write a function that reads from the opened data file: the numberof integers the user wants to read, and store the numbers inthe array. For example, if the user wants to read 13 numbers,read 13 of the 20 that may be in the file.7. Write a function that writes to the opened output file AND THECONSOLE, the numbers stored in the array.8. NO GLOBAL variables are to be used. The input and output file variablesmust be passed…
