Text analysis problem

[haz115]

How could I write a program that reads a file of words (assumed to be in lower case letters) and prints out the total number of words in the file?

Would it be something like this?:


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

int main()
{
int ch;
FILE *input_ptr;

if((input_ptr=fopen(“infile.txt”,”rt”))==NULL)
{
printf(“Cannot open input file/n”);
exit(1);
}



fclose(input_ptr);

return 0;

}

I don't know how to do the bit in the middle.

If anyone can help, thank you very much.

I will not code the solution for you but will give a hint - words are usually separated by a space. If you count the number of spaces then maybe add one more for the last word before the eof character, then that should take care of it.

ok, would it be something like this:

while ((ch=fgetc(input_ptr))!=EOF))
{
if ((ch == 0x20) /*or should I write ==' ' ?*/
++count
}

printf("The number of words is %d\n", count-1);

int count = 0;

while ((ch=fgetc(input_ptr))!=EOF)) 
{ 
if ((ch == '  ' ) /*one space */
count++;
} 
count++;

printf("The number of words is %d\n", count);
