Write a program to find the number of times that a given word(i.e. a short string) occurs in a sentence (i.e. a long string!). Read data from standard input. The first line is a single word, which is followed by general text on the second line. Read both up to a newline character, and insert a terminating null before processing. Typical output should be: The word is "the". The sentence is "the cat sat on the mat". The word occurs 2 times.
