c++ - Print duplicates of strings -

i working code find amount of duplicated words imported file. input stream represents file containing series of lines. function should examine each line looking consecutive occurrences of same token on same line , print each duplicated token along how many times appears consecutively. non-repeated tokens not printed.

here have:

#include <iostream> #include <fstream> #include <cstdlib> #include <string> using namespace std; int main() { ifstream in("file.txt"); if (! in) { cerr << "could not open file.txt."; homecoming exit_failure; } string str; int count = 0; int len=str.length(); while(getline(in,str)){ for(int = 0; < len; i++){ if(str.at(i) == str.at(i+1)){ count++; } else if(str.at(i) != str.at(i+1)){ i++; } } cout << str << "*" << count << endl; } }

the .txt contains:

hello how how you you i jack's jack's smirking smirking smirking smirking smirking revenge bow wow wow yippee yippee yo yippee yippee yay yay yay 1 fish 2 fish reddish fish bluish fish it's muppet show, wakka wakka wakka

the output should be:

how*2 you*4 i*3 jack's*2 smirking*5 wow*2 yippee*2 yippee*2 yay*3 wakka*3
