Thread: How to count number of spaces, certain letters, etc. in strings?

Hello, I was wondering if anyone knew how to get a program to count the number of certain elements in a string.

Here's an example code I made. How would I determine the number of spaces in line1 and the number of punctuation marks in line2 that would return that back to the main?

Code:

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


int spaceCount(char line1[]);
int locatePunctuation(char line2[]);


void main()
{
            char line1[] = "I like chocolate chip cookies."
            char line2[] = "Hi. My name is DW. How are you today?"
            printf(spaceCount(line1));
            printf(locatePunctuation(line2));


}


int spaceCount (char line1[])
{


}


int locatePunctuation(char line2[])
{


}

I'm guessing for punctuation I would need something like (correct me if I'm wrong):

Code:

int count = 0, i;
for(i = 0; i < strlen(line);i++) // counts # of punctuation marks in the string
{
          if(ispunct(line[i] )) { count++; }
}
printf(“%d \n”, count);

??

Not sure about spaces though.

Thanks!

Look up the following functions in your C library documentation...
(If you don't have it.. get it.)

ispunct()
isspace()
isalpha()
isdigit()

Ah that helped. Thank you very much!
