In c++

Write a function that:

accepts a string and an integer as it's only arguments
uses the argument to open a file for writing
writes the integer to the file
if it fails to open the file, returns -1
if it succeeds in opening the file, returns 0
does not interact with the user in any way
does not use global variables

Expert Solution

#include <iostream>
#include <fstream>
using namespace std;

int func(string s,int n){// functions accepting a string and integer
  fstream filestr;
  filestr.open ("test.txt");
  if (filestr.is_open())
  {
    filestr << n;// write the integer to file
    filestr.close();
    return 0;
  }
  else
  {
    return -1;// return -1 if file is not open
  }
  
    }

int main () {
    cout<< func("a",2);
    
}

Execution output:

integer written to file:

Write a function in JAVASCRIPT that accepts two arguments (a string array and a character). The function will check each character of the strings in the array and removes the character, regardless of case. If the first letter of the string is removed the next letter must be capitalized. Your function would return the result as one string, where each element of array is separated by comma. E.G. function([“John”,”Hannah”,”Saham”], “h”); // returns ‘Jon,Anna,Saam Use of any built in string function...

Make a python code. Write a function named max that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 7 and 12 are passed as arguments to the function, the function should return 12. Use the function in a program that prompts the user to enter two integer values. The program should display the value that is the greater of the two. Write the program as a loop that...

Using Python #Write a function called after_second that accepts two #arguments: a target string to search, and string to search #for. The function should return everything in the first #string *after* the *second* occurrence of the search term. #You can assume there will always be at least two #occurrences of the search term in the first string. # #For example: # after_second("11223344554321", "3") -> 44554321 # #The search term "3" appears at indices 4 and 5. So, this #returns everything...

C programming Write a function called string in() that takes two string pointers as arguments. If the second string is contained in the first string, have the function return the address at which the contained string begins. For instance, string in(“hats”, “at”) would return the address of the a in hats. Otherwise, have the function return the null pointer. Test the function in a complete program that uses a loop to provide input values for feeding to the function.

R programming language A) Create a function that accepts two arguments, an integer and a vector of integers. It returns the count of the number of occurrences of the integer in the input vector. 1]Input: num_count <-function ??? 2]Input: num_count(2,c(1,1,2,2,3,3)) 2] Output: 2 3] Input: num_count(1,c(1,1,2,2,3,1,4,5,5,2,2,1,3)) 3] Output : 4 B) Create a function that accepts 3 integer values and returns their sum. However, if an integer value is evenly divisible by 3, then it does not count towards the...

program c Write a program called filesearch that accepts two command-line arguments: A string A filename If the user did not supply both arguments, the program should display an error message and exit. The program opens the given filename. Each line that contains the given string is displayed. Use the strstr function to search each line for the string. You may assume no line is longer than 255 characters. The matching lines are displayed to standard output (normally the screen).
