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:

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.
