fgets don't work as I expected with this code

[Awareness]

I have a problem with the codes below.I am trying to do an exercise from a C book.My code first asks for user input,then it seperates the given input into it's "atoms".Then it changes the words like this:Let's say one of the word is "soccer",my program tries to change it to "occersay",it puts the first letter of the word after the last
letter of the word and it adds "ay" to the last part of the word.

But the problem is,if I use fgets for asking user input,it runs as this:

Please write a sentence without using any punctuator: We play soccer

eWay
laypay
occer
say

As you see,it automatically passes to newline before putting "s" and "ay" after the "occer",though it works well

with previous words.
If I use gets(sentence) instead of fgets(sentence,50,stdin) then no problem,it works as I expected.

Is there a way to do same thing with fgets?I have read on internet that gets has not been a type-safe function and it was recommended to use fgets instead of gets.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void lwords(char*);

int main()
{
char* sentence=(char*) malloc(150);

printf("Please write a sentence without using any punctuator: ");

fgets(sentence,50,stdin);


char* word=strtok(sentence," ");



while (word!=NULL)
{

lwords(word);
word=strtok(NULL," "); 

}

free(sentence);

}


void lwords(char* word)
{
char* plat=(char*) malloc(40);


strcpy(plat,word);


int stringsize=strlen(plat);
memmove(&plat[strlen(plat)],&plat[0],1);

plat[(stringsize+1)]='\0';

sprintf(plat,"%s%s",plat,"ay");

memmove(plat,&plat[1],strlen(plat)); 

printf("%s\n",plat);


}

Is there a newline that you're grabbing instead of ignoring?

Thanks for your answer.I press "enter" key after writing the text,other then that I don't think there is a newline...

Additionally,I forgot to say that it is always the last word of the sentence which a newline is put after,before "ay".

Yes, I think your program is reading the new line character(s) when you press enter. I'll bet if you press space before enter it will do something you wouldn't expect...

Thanks for your answer.Is it possible to fix this problem?(other than using gets?

Using word=strtok(NULL," \n"); instead of word=strtok(NULL," "); solved my problem...
