Array of pointers (chars)

Hello, I need to make a function that will receive an array of pointers of chars and an char. The function will check how many times the char appears in the array, example:

Code:

---

char *msg[] = {
        "String one",
        "String two",
        "String three",
        "String four",
    };

---

Now I pass to the function the array and the char 'e' the function will return me 3.

Now the question, after that I pass the function, what should I do? I need to check char by char? hmm, I don't need that you make me the whole program, I just need to understand, thanks :)

You could write a function which counts the number of occurrences of a character in a string and pass each string to this function. Checking each character is the easiest way.

Ok Shiro I get you.

Code:

---

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

int cama (char *msg, char src);

int main(void)
{
    int len = 0, i;
    char *msg[] = {
        "String one",
        "String two",
        "String three",
        "String four",
    };
   
    for(i=0;i<5;++i)
        len += cama(*(msg+i),'e');
   
   
    printf("The char 'g' appears %d\n",len);
    getchar();
    return 0;
}

int cama (char *msg, char src)
{
    int len = strlen(msg);
    int i,l = 0;
   
    for(i=0; i<len; ++i,++msg)
        if(*msg == src)
          ++l;
   
    return l;
}

---

But it's not better to pass all the array of pointers instead checking string by string or its the same thing?

Thank you!

Currently you have the functionality distributed over main and the function. Main() passes each string to the function and the function determines the number of occurrences. You could make your function more general by letting it accept an array of strings. Then you could just pass the array of strings to the function and let the function do all the work.

I would prefer to let functions do the work and let main() do only a few necessary things, but that's a matter of opinion.

Ok, I'll change the main function, and let the other function to treat with the strings :)

Thank you.

Forgot one thing to tell, the main reason for making general functions and putting code into functions is reusability of code.
