求大神帮小白找c语言bug所在？

Question

找出字符串中的最长单词并输出：

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

int main(int argc, const char * argv[]) {
    
    char str[] = "adventure may hurt you but monotony will kill you";
    char *p;
    int count = 0;
    int maxlen = 0;
    int lenth = 0;
    int maxIndex = 0;
    for ( p = str ; *p!= '\0' ; p++) {
        
        if (*p != ' ') {
            lenth++;
        }else{
            
            if (lenth >= maxlen) {
                maxlen = lenth;
                maxIndex = count;
                lenth = 0;
            }
            
        }
        count++;
    }
    for (int i = 0; i < maxlen; i++) {
        printf("%c",str[maxIndex-maxlen+i]);
    }
    
    return 0;
}

Answer 1

if (lenth >= maxlen) {

        maxlen = lenth;
        maxIndex = count;
        lenth = 0;
    }else{
    lenth=0;

}
