Question

write a function to count the presence of words he and she & the number of line contains words he and she in a text file "story.txt"&

Answer 1

//initialize counter variables

//initialize buffer(stack) for words & char for character
const int BUF_SIZE = 6;

//continuous variable will determine the continuous sequence of characters

//output results

cin.get();//suspend the console
