Question

Write a program that reads text from one file and writes an edited version of the same text to another file. The edited version is identical to the unedited version except that every string of two or more consecutive blanks is replaced by a single blank. Thus, the text is edited to remove any extra blank characters. Your program should define a function that is called with the input- and output-file streams as arguments. If this is being done as a class assignment, obtain the file names from your instructor.

Explanation / Answer

code:

#include <bits/stdc++.h>
using namespace std;

void f(ifstream& inf,ofstream& outf){
  
   string s;
   while(getline(inf,s)){
       int l=s.length();
       char pre='a';
       for(int i=0;i<l;i++){
           if(pre==' ' && s[i]==' '){

           }
           else{
               pre=s[i];
               outf<<s[i];
           }
       }
       outf<<endl;
          
   }
}

int main(){
   ifstream inf;
   inf.open("input.txt");
   ofstream outf;
   outf.open("output.txt");
   f(inf,outf);

   return 0;
}
