Thread: Line break when space and tell me what is its pats of speech c program.

Hi, I am a beginner at c program. I need a program of Line break when space and tell me what is its pats of speech c program.

Welcome to the forum.

Your question is not really clear, so please read this (don't take the title personally): How To Ask Questions The Smart Way

If there's a language barrier, no big deal, just try your best to explain and we'll try our best to understand.

Also, be sure to show your best attempts at solving the problem you're having (as per the homework policy) - and if posting code, be sure to use code tags.

The Input is Like "This is me"

Output will be:

"
This is a pronoun
is is a verb
me is a pronoun

"

That clarifies the requirements. What have you tried?

Are you already familiar with some other programming language, along with common algorithms and data structures?

Code:

#include <stdio.h>
#include <conio.h>
int main(){
{
  char st[] ="This is a line";
  char *ch;
  printf("Split \"%s\"\n", st);
  printf("\n");
  ch = strtok(st, " ");
  while (ch != NULL)
    {
        char aa[]=ch;


        if(aa[]="This")
        {
            printf("This is a Pronoun");
        }






        else if(aa[]="is")
        {
            printf("This is a Pronoun");
        }


        else if(aa[]="a")
        {
            printf("This is a article");
        }


        else if(aa[]="line")
        {
            printf("This is a noun");
        }
        break;
    }
  getch();
  return 0;
}
}

1. You don't need "conio.h" - it's outdated, and you aren't using it for anything (expect apparently to keep the console window open - see here for better alternatives: FAQ > Stop my Windows Console from disappearing everytime I run my program? - Cprogramming.com)

2. A single = is used for assignment, whereas a double == is used to test for equality; but...

3. You can't compare strings in C using == ... you need to use the string compare function "strcmp()"

I haven't dug much deeper into the code you provided - start by fixing those things up and trying to compile, and check back with your updated code.

In fact, I'd recommend starting over, and building your program gradually, testing as you go - see here: A development process

I'm also pretty sure you need to develop a more general solution, instead of checking for the specific words in the given example.

You should use strcmp to compare strings, e.g.,

Code:

char *word = strtok(line, " ");
while (word)
{
    if (strcmp(word, "This") == 0) {
        printf("This is a Pronoun\n");
    }
    /* ... */
    word = strtok(NULL, " ");
}

Notice the '\n' that is used to print a newline. You should #include <string.h> for strcmp.

Furthermore, notice that I called strtok at the end of the loop body. Otherwise, you would never proceed to the next token. I have taken the liberty of renaming your variables: frankly, "st" and "aa" are poor variable names here as they are not descriptive.

Please can you provide me full code for that problem ?
