how to write a function definition to match given function interference, the code does not have to work, it is just for my understanding. int save_array(const char *filename, const int *a, int n ); //REQUIRES: filename points to the start of a string. // n>0 and element a[0]....a[n-1] exist. // PROMISE: // if the test file with name filename can be successfully opened, // the value of n is printed to the file, followed by the values of // a[0]....a[n-1], one number per line // the return value is 0 for success, 1 for failure to open the file, // and 2 if an error is detected closing the file

a C++ program that creates a two-dimensional integer array (4x3) initialized with user given data. The program should have the following functions: • Print the sum of all values in the array. • Print the average of all the values in the array. • Take row number from user and print the sum of the values in that specified row.(use loop and no if statement) • Take column number from user and print the sum of the values in that specified column.(use loop and no if statement)
C++ Programming: How would you write a function that takes a filename and an array of struct time, opens a file, reads each line in the file as the number of days, converts this to a struct time and stores this is in an array? Here is my code so far (p.s. the function i need help with is called void readData): #include<iostream>#include<string>#include<fstream>#include<cstdlib>#include<vector> using namespace std; struct time{// private:int years, months, days;//public: time(){}time(int days){}}; time getYearsMonthsDays(int days){time x;x.years = days/450;days = days%450;x.months = days/30;x.days = days%30;return x;} int getTotalDays(time x){int totalDays;totalDays = x.years*450 + x.months*30 + x.days;return totalDays;} void openofile(string ofilename,ofstream &fout){fout.open(ofilename.c_str());if(!fout){cout << "Error opening output file..." << endl;exit(1);}} void openifile(string ifilename,ifstream…
Create a dynamic array that contains an int array. dynamic array, array inside when the existing array is full and a new element needs to be added will double its size, make all the elements of the old array the same will copy the indexes and add the element to the new array. Use the following functions. Write in C language. 1.append(dynamic array, new element): function sent to itself Adds the element sturct to the end of the array inside DynamicArray. Place If not, it behaves in accordance with the dynamic array definition given above. 2. get(index): The element in the index sent to it by the function takes it from the array it hosts and sends it back. ATTENTION ! : Please use a dynamic array and this array with struct structure. I don't want a link list. Do not post wrong or copied codes. Be sure to use the append and get functions given above Please do not solve the question I asked with the same code and copy and paste the code, my right to the question is running out. Solve the…

Instructions Write a program in C++ that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and the highest and lowest temperatures for the year. Your program must consist of the following functions: Function getData: This function reads and stores data in the two-dimensional array. Function averageHigh: This function calculates and returns the average high temperature for the year. Function averageLow: This function calculates and returns the average low temperature for the year. Function indexHighTemp: This function returns the index of the highest high temperature in the array. Function indexLowTemp: This function returns the index of the lowest low temperature in the array. These functions must all have the appropriate parameters. An example of the program is shown below: Enter high temperature for each month 60 68 72 72 73 76 80 81 75 72 67 66 Enter low temperature for…

In c++, write a function countletters that counts the number of times a particular letter occurs in an array. The function should have three arguments: the array that holds the characters; the letter you are searching for; and the number of characters in the array. It should return a count.
This is for C++ Design an application that has an array of at least 20 integers. It should call a module that uses the sequential search algorithm to locate one of the values. The module should keep a count of the number of comparisons it makes until it finds the value. Then the program should call another module that uses the binary search algorithm to locate the same value. It should also keep a count of the number of comparisons it makes. Display these values on the screen. 7 Searching Benchmarks (integer array search) Modify the textbook instructions as follows: Use the output of one of the array sorting algorithms from exercise 8. Search the resulting sorted array using both the Sequential search and Binary search. Count and display the number of comparisons in both cases.
