Turning program into reusable function in C help???

Question

https://code.sololearn.com/cR0VbZRJ37G7

I would like to change the following into a reusable function that accepts a string and returns a multidimensional array of word strings. Any help is greatly appreciated. Specifically what does the function declaration look like and then a main below it that gets the string as input and prints the words maybe???

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

int main(){
char input[200], word[20][20];
int inputLength, i, j = 0, wc = 0;
fgets(input, 200, stdin);
inputLength = strlen(input);
for (i = 0; i <= inputLength; i++){
if (input[i] == ' ' || input[i] == '\0')
{
word[wc][j] = '\0';
j = 0;
wc++;
}
else
{
word[wc][j] = input[i];
j++;
}
}
printf("Original sentence: %s\n", input);
for(i = 0; i < wc; i++){
printf("Word %d: %s\n", i + 1, word[i]);
}
return 0;
}

Answer 1

I took an interest in this and gave it a try. The split() function modifies the word array passed in argument (because arrays in C are passed to a function as a pointer to the first element). The word count is returned, so we have right upper limit in the printing loop.

Do you hear about strtok function in <string.h>? It allow to split a sentance into separate words.
