编译器不在codeblock中执行程序

Question

我正在编写一个代码，用于打印由我输入的字符串中最长的单词。 但程序没有执行，并且收到错误消息以关闭程序。

Answer 1

这是我重写的代码 - 答案---`

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

int main(){
   char my_str[] = "in this program we will find the longest keyword used so 
   that we can";


int longest = 0; 
char word[20];      
char longestWord[20]; 

int i = 0, j;

while(my_str[i]!='\0'){
    j = 0;
    while(my_str[i]!=' ' && my_str[i]!='\0'){
        word[j++] = my_str[i++];
    }
           word[j] = '\0';
    if (strlen(word) > longest){
        longest = strlen(word);
        strcpy(longestWord, word);
    }

    if (my_str[i] == ' '){
        i++;
    }
}
printf("Longest word: %s\n", longestWord);
printf("Length: %d\n", longest);

return 0;
}

Answer 2

这不是代码块的错误。你的程序开始实际运行，但随后它崩溃（由于segmentation fault）和windows / codeblock显示这个＆＃34; ...已停止工作＆＃34;消息。

导致崩溃的实际行是longest行

strcpy(longestword,longest);

我相信你的意思是longestword。

还要注意你的代码在语法（在执行它之前阅读编译器的警告）和逻辑中都会有更多的错误。
