C Programming - Reverse Words in a String (In-Place)

Another typical interview question!!

Here is the solution that I could think off...Post your comments!!!

Solution:


#include < stdio.h >
#define SENT "Hello I am Here"

int reverse(char *string, char delimiter)
{
    char *src, *dest,*temp=string;
    while( *temp ) {
         if (*temp == delimiter) {
                     temp++;
                     continue;
         }
         src=dest=temp;
         while ( (*(dest+1) != delimiter) && ( *(dest+1) != '\0' ) ) dest++;
         temp=dest+1;
         while( dest > src ) {
                char temp = *dest;
                *dest-- = *src;
                *src++=temp;
         }
    }
}


int main()
{
    char name[] = SENT;
    printf("Before Call: %s\n",name);
    reverse(name,'\0'); /* Reverse Complete Sentence */
    reverse(name,' '); /* Reverse Words */
    printf("After Call: %s\n",name);
    
}
