Passing multiple strings into a function - c

Question

i am trying to read several strings into a function for processing. The instructions are to pass each string into the function (not create a 2d array of strings). The parameters must stay the same. Here is what i tried
#include <stdio.h>
#include <math.h>
void convert(char s[]), int counts[]);
int main(void)
{
int i = 0;
int d[2] = {};
char text0[] = "this IS a String 4 you.";
char text1[] = "This sample has less than 987654321 leTTers.";
while(i<2)
{
convert (text[i],d); """ this is wrong but i dont know how to correctly do this
i = i +1;
}
}
void convert(char s[]), int counts[])
{
printf("%s this should print text1 and text2", s );
}
So i have a couple of questions. Is there some sort of special character/operator similiar to the glob module in python that can correctly do the convert (text[i],d) part for me where i try to read in each string. Also the int counts[] purpose is to be filled in with the word and character count in the function. So if i fill in this array in function convertwill main also recognize it since i need to print the word/character count in main without returning the actual counts in convert

Answer 1

You could use temporary string pointer array to pass all strings:
char text1[] = "This sample has less than 987654321 leTTers.";
char const * texts[] = { text0, text1 };
convert (texts, 2, d);
}
void convert(char const * s[], size_t n, int counts[])
{
while(n--) {
*counts++ = strlen(*s);
printf("%s\n", *s++);
}
}
Some notes:
I added char const to function argument type. You should always do that when function does not change the string. If you need to change the string in function, just remove the const.
There is extra argument size_t n to pass array array element count to function. size_t can be found in stddef.h.

Answer 2

i think u lost a "(" in "void convert(char s[]), int counts[]);".
it should be void convert((char s[]), int counts[]);

Answer 3

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
void convert(char s[], int counts[]);
int main(void){
int i = 0;
int d[2] = {0};
char text0[] = "this IS a String 4 you.";
char text1[] = "This sample has less than 987654321 leTTers.";
char *text[] = { text0, text1 };
for(i=0; i<2; ++i){
convert (text[i], d);
printf("%d, %d\n", d[0], d[1]);
}
}
void convert(char s[], int counts[]){
printf("%s\n", s );
{
char *temp = strdup(s);
char *word, *delimiter = " \t\n";//Word that are separated by space character.
int count_w=0, max_len=0;
for(word = strtok(temp, delimiter); word ; word = strtok(NULL, delimiter)){
int len = strlen(word);
if(max_len < len)
max_len = len;
++count_w;
}
counts[0] = count_w;
counts[1] = max_len;
free(temp);
}
}
