printing a word per line - c

Question

I need to write a program that prints its input one word per line. Here's what I got so far:
#include <stdio.h>
main(){
int c;
while ((c = getchar()) != EOF){
if (c != ' ' || c!='\n' || c!='\t')
printf("%c", c);
else
printf("\n");
}
}
The logic is pretty simple. I check to see if the input is not a newline, tab or space, and in that case it prints it, otherwise prints a newline.
When I run it, I get results like this:
input--> This is
output--> This is
It prints the whole thing. What goes wrong here?

Answer 1

if (c != ' ' || c!='\n' || c!='\t')
This will never be false.
Perhaps you meant:
if (c != ' ' && c!='\n' && c!='\t')

Answer 2

instead of using printf try putchar, also as per above comments, you should use && instead of ||.
here is my code-
#include<stdio.h>
main()
{
int c, nw; /* nw for word & c for character*/
while ( ( c = getchar() ) != EOF ){
if ( c != ' ' && c != '\n' && c != '\t')
nw = c;
else {
nw = '\n';
}
putchar (nw);
}
}
this code will give you the desired output

Answer 3

you can use if you want the strtok function in string.h library which can cut the input into many words by providing a delimiter.
Here is a perfect code commented which can fit to your needs
#include <stdio.h>
#include <string.h>
int main(int argc, char *argv[])
{
char line[1000]=""; // the line that you will enter in the input
printf("Input the line:\n>>");
scanf("%[^\n]",line); // read the line till the you hit enter button
char *p=strtok(line," !#$%&'()*+,-./'"); // cut the line into words
// delimiter here are punctuation characters (blank)!#$%&'()*+,-./'
printf("\nThese are the words written in the line :\n");
printf("----------------------------------------\n");
while (p!=NULL) // a loop to extract the words one by one
{
printf("%s\n",p); // print each word
p=strtok(NULL," !#$%&'()*+,-./'"); // repeat till p is null
}
return 0;
}
If we execute the code above we will get
Input the line:
>>hello every body how are you !
These are the words written in the line :
----------------------------------------
hello
every
body
how
are
you

Answer 4

suggest the code implement a state machine,
where there are two states, in-a-word and not-in-a-word.
Also, there are numerous other characters that could be read
(I.E. ',' '.' '?' etc) that need to be check for.
the general logic:
state = not-in-a-word
output '\n'
get first char
loop until eof
if char is in range a...z or in range A...Z
then
output char
state = in-a-word
else if state == in-a-word
then
output '\n'
state = not-in-a-word
else
do nothing
end if
get next char
end loop
output '\n'

Answer 5

I think the simple solution would be like
#include <stdio.h>
int main(void) {
// your code goes here
int c;
while((c=getchar())!=EOF)
{
if(c==' ' || c=='\t' || c=='\b')
{
printf("\n");
while(c==' ' || c=='\t' || c=='\b')
c=getchar();
}
if(c!=EOF)
putchar(c);
}
return 0;
}
