C program to count words in a given string/sentence?

I want to count the words in a given string by counting the spaces between them. Here's the code that i've tried.

#include<stdio.h>
#include<conio.h>
#include<string.h>
main()
{
 int t,i,b=1;
 char a[100];
 printf("Enter a sentence: ");
 gets(a);
 t=strlen(a);
 for(i=0;a[i]!='\0';i++)
 {
      if(a[i]=' ')
      {
           b++;
      }
 }
 printf("The number of words in the above sentence are %d",b);
 getch();
}

But i am unable to get the output. I keep getting wrong number of words.

Thanks. :D

Solution

  • You are using the assignment operator = for comparison

    if(a[i]=' ')

    you need ==

    if(a[i] == ' ')

    some people use this

    if (' ' == a[i])

    to prevent this kind of mistake.
