问题:输出字符串中最长的单词
感谢您提供了修改后的代码。我注意到在定义字符数组 a 时,您使用了大括号 {} 将字符串括起来,这是导致程序无法正确输出结果的原因之一。在 C 语言中,使用双引号 "" 来定义字符串,不需要额外的大括号。
另外,修改后的代码中还有几处逻辑错误和小问题。我已经帮您进行了修正和优化,以下是修改后的代码:
- #include <stdio.h>
- #include <string.h>
- void Longest(char a[]) {
- int count = 0, maxCount = 0;
- int sign = 0, maxStart = 0;
- for (int i = 0; i < strlen(a);) {
- if ((a[ i] >= 'a' && a[ i] <= 'z') || (a[ i] >= 'A' && a[ i] <= 'Z')) {
- int num = 1;
- for (int j = i; j < strlen(a);) {
- if ((a[j + 1] >= 'a' && a[j + 1] <= 'z') || (a[j + 1] >= 'A' && a[j + 1] <= 'Z')) {
- j++;
- num++;
- } else {
- if (num > count) {
- count = num;
- sign = i;
- }
- i = i + num - 1;
- break;
- }
- }
- } else {
- i++;
- }
- }
- printf("最长的单词有 %d 位,是:", count);
- for (int i = sign; i < sign + count; i++) {
- printf("%c", a[ i]);
- }
- printf("\n");
- }
- int main(void) {
- char a[1000] = "Graph convolutional networks (GCNs) have been widely used and achieved remarkable results in skeleton-based action recognition.

- Longest(a);
- return 0;

在修正后的代码中,主要进行了以下改进:
1. 移除了字符数组 a 定义时的多余大括号。
2. 修正了变量的命名和作用域,以保证正确的结果输出。
3. 优化了循环和条件语句的结构,以提升代码的可读性和效率。
现在,修改后的代码应该能够正确输出字符串中最长的单词及其长度。希望对您有所帮助!如果还有其他问题,请随时提问。
