Here's an example C code for the given problem:
```c
#include <stdio.h>
#include <string.h>

void reverse_word(char *str, int index) {
int len = strlen(str);
if (index >= len / 2) return;

char temp = str[index];
str[index] = str[len - index - 1];
str[len - index - 1] = temp;

reverse_word(str, index + 1);
}

int main() {
char input[] = "this is the line of text";
reverse_word(input, 0);
printf("%s", input);
return 0;
}

Is main is user defined function?
