认知 行动 坚持

打算开始写博客了，相当于一个电子笔记。不管未来如何，希望自己能持续积累，坚持下去。从简单的字符串复制开始吧：

#include<iostream>using namespace std;void myStrLink(char *head, char *tail){ while(*head) head++; //不能写成while(*head++); while(*head++ = *tail++);}int main(){ char head[20] = "hello"; char tail[10] = "world"; myStrLink(head, tail);

#includeusing namespace std;int myStrCmp(char str1[], char str2[]){ int i; for(i = 0; str1[i] && str2[i]; i++) { if(str1[i] > str2[i]) return 1; if(str1[i] < str2[i]) return -1; }

#includeusing namespace std;int myArrayToInt(char str[]){ int i, sum = 0; for(i = 0; str[i]; i++) { // 'x' - '0' = x (x = 0, 1, 2,..., 9) sum = 10 * sum + str[i] - '0'; } retur

#includeusing namespace std;void reversePartStr(char str[], int first, int last){ char tmp; int length = last - first + 1; int i; for(i = 0; i < length / 2; i++) { tmp = str[fir

#includeusing namespace std;int getStrLen(char str[]){ return *str ? getStrLen(str + 1) + 1 : 0;}int main(){ char str[] = "abc"; cout << getStrLen(str) << endl; return 0;}

#includeusing namespace std;void reverseString(char str[]){ int length = strlen(str); int i, tmp; for(i = 0; i < length/2; i++) { tmp = str[i]; str[i] = str[length - 1 - i]; s

#includeusing namespace std;void reverseString(char str[], int left, int right){ int i = left; int j = right; char tmp; while(i < j) { tmp = str[i]; str[i] = str[j]; str[j]

周六，小雨，写个字符压缩代码，来玩一下。 压缩示例：a b b c c c d e ea b 2 c 3 d e 2a b b c c c d e fa b 2 c 3 d e faaa ba ba aa 2a a aa 3 代码：#include &lt;iostream&gt;#include &lt;cassert&gt;using n...
