Write a program that replaces words in a sentence. The input begins with an integer indicating the number of word replacement pairs (original and replacement) that follow. The next line of input begins with an integer indicating the number of words in the sentence that follows. Any word on the original list is replaced.

Ex: If the input is:

3 automobile car manufacturer maker children kids

15 The automobile manufacturer recommends car seats for children if the automobile doesn't already have one.

then the output is:

The car maker recommends car seats for kids if the car doesn't already have one.

The program above is my work, I just need help to know what I did wrong. Someone please help

Answer 1

THe program works correctly...

the debugging statements were left in so you can see that the input is working correctly...

you can comment the cout statements in the first two for loops to shut the debugging off...

I do not have that version of C++, so I had to use an array of structures instead of the vector...

each data structure contains the word to be replaced along with it's synonym which replaces it.,,

an array of these synonyms is created in the first for loop...

the second for loop creates an array of the words in the sentence...

while these words are input, it is looked up via the function to see if it's synonym is in the array...

if so, a non-negative index is returned; the word is replaced with the synonym right then and there...

the only improvement that can be made is to free the arrays before the end of the program...

the last two statements can be:

free(synonyms);

free(words);
