在字符串中打印中间单词。 C程序设计

Question

I need help on code that print out a middle word of string.

First Example:

Input: My name is Alex

Output: either name or is <-- is the middle

Second Example:

Input: Hello. I Need help on my coding.

Output: Help <-- middle word

Hopefully someone can help me out. I will try to follow up.

Answer 1

Here's an idea:

1. Split string into words
2. Now that you know how many words there are, decide how to handle the even case
3. Print the decided words

You can use strtok() for the splitting, and perhaps assume that a "typical" sentence has not more than 50 words, each being no longer than 16 characters. Just to simplify the code.

Answer 2

The full code :

#include <stdio.h>
#include<string.h>
#include<conio.h>
int main(){
char str[] = "good men to come to the aid of their country";
char delims[] = " ";
char *result;
char word[100][100];
int loop=1;
result = strtok(str, delims );
strcpy(word[0],result);
while( result != NULL ) {
    loop++;

    strcpy(word[loop],result);
     result = strtok( NULL, delims );

   }
int mid=loop/2-1;
// to print the middle element
printf("word is %s \n",word[mid+1]);
getch();
return 0;
