              if (words[i][0] == *p)
                 found = 1;
              p++;      
          }
          if (found == 1)

Here is the main function that you must use. You may not add or remove parameters or change the names of the variables. You must initialize the values of the variables.: int main (int argc, char argv)t //Check correct number of argument:s if ( argc != 5 ) { cout

Explanation / Answer

Hi, here is the replaceWord function, you need,

void replace(string &word,char toReplaceInword)

{

if(word[0]==toReplaceInword) //check if it starts with given char

word="----"; //set the word to 4 dashes

}
Thumbs up if this was helpful, otherwise let me know in comments.
