C语言寻找长度最长的单词

以下是C语言寻找长度最长的单词的代码实现：

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

void findLongestWord(char sentence[]) {
    int i, length, max = 0, start = 0, end = 0;
    length = strlen(sentence);
    for (i = 0; i < length; i++) {
        if (sentence[i] == ' ') {
 if (i - start > max) {
                max = i - start;
                end = i - 1;
            }
            start = i + 1;
        }
    }
    if (length - start > max) {
        max = length - start;        end = length - 1;
    }
    printf("The longest word is: ");
    for (i = end - max + 1; i <= end; i++) {
        printf("%c", sentence[i]);
    }
}

int main() {
    char sentence[100];
    printf("Please enter a sentence: ");
    gets(sentence);
    findLongestWord(sentence);
    return 0;
}
