Question

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

Answer 1

#include<iostream>
#include<fstream>
using namespace std;
//method to write the integer into file
int Write(string str,int n)
{
    ofstream outFile;//declare file object
    outFile.open(str.c_str());//open the file
    if(!outFile) //condition for unable to open the file
        return -1;//return -1
   
   outFile<<n;//write n into file
   outFile.close();//close the file
   return 0;//return 0  
}
//driver code
int main()
{
   string str = "WriteData.txt";//initialize the string variable by a name of file
   int n=14;//initialize n
   //call to Write()
   Write(str,n);
}
