4. 输入若干个字符串(最多10个)，求出每个字符串的长度，并打印最长字符串的内容。以“stop”作为输入的最后一个字符串。
程序代码：
#include <stdio.h>
#include <string.h>
#define MAX_STRINGS 10
#define MAX_LENGTH 100
void printLongestString(char strings[][MAX_LENGTH], int count) {
int longestLength = 0;
char longestString[MAX_LENGTH];
for (int i = 0; i < count; i++) {
int currentLength = strlen(strings[i]);
if (currentLength > longestLength) {
longestLength = currentLength;
strcpy(longestString, strings[i]);
}
}
printf("最长的字符串是: %s\n", longestString);
}
int main() {
char strings[MAX_STRINGS][MAX_LENGTH];
int count = 0;
printf("请输入字符串 (最多10个)，以 'stop' 结束输入：\n");
while (count < MAX_STRINGS) {
printf("字符串%d: ", count + 1);
scanf("%s", strings[count]);
if (strcmp(strings[count], "stop") == 0) {
break;
}
count++;
}
printf("\n");
printf("每个字符串的长度：\n");
for (int i = 0; i < count; i++) {
printf("字符串%d: %d\n", i + 1, strlen(strings[i]));
}
printf("\n");
printLongestString(strings, count);
return 0;
}
