i str2 len2 0 count return count 输出的结果是 子字符串个数是 3 例 4 简单的字符统计 include include include int main int len i a 128 0 p char str char malloc sizeof char 40 gets str len strlen str for i 0 i len i p str i a p for i 1 i 128 i if a i 0 printf c d i a i printf n return 0 例 5 删除字符串中字符数最少的字符 include include int main char str affddsass int len strlen str int a 128 0 int p min i k 0 char b 128 for i 0 i len i p str i a p i 0 while a i 0 i min a i for i 0 i 128 i if a i 0 for i 0 str i 0 i if a str i min b k str i b k 0 for i 0 b i 0 i putchar b i putchar n return 0 输出结果 sss 例 5 用指针求出字符串长度 include include int main int length 0 char str 50 char pstr str printf Please input a string n gets str while pstr length printf 字符串的长度 d n length return 0 例 6 字符串中子字符串的替换 include include char strReplace char s1 char s2 char s3 int main char s1 abcdefbbbsddsbbb char s2 bbb char s3 ggg char ps strReplace s1 s2 s3 puts ps return 0 char strReplace char s1 char s2 char s3 int i int len1 strlen s1 int len2 strlen s2 int len3 strlen s3 for i 0 i len1 len2 i if strncmp s1 i s2 len2 0 strncpy s1 i s3 len3 return s1 输出结果 abcdefgggsddsggg 例 7 字符串间隔输出 编写一个程序实现功能 将字符串 Computer Secience 付给一个字符数组 然后从第一 个字母开始间隔的输出该串 用指针完成 include include int main int flag 1 char str Computer Secience char pstr str while pstr if flag putchar pstr flag flag 1 2 pstr printf n return 0 输出结果 Cmue eine 例 8 两个字符串合并 编写一个程序实现一个功能 将两个字符串合并为一个字符串并且输出 用指针实现 include include int main char str1 20 hello char str2 10 world char pstr1 str1 char pstr2 str2 while pstr1 pstr1 while pstr2 pstr1 pstr2 pstr1 pstr2 pstr1 0 puts str1 return 0 输出结果 hello world 例 算分数的问题 算分数问题 去掉一个最高分一个最低分 求平均分 include include float avescore float score int len int main float score 6 70 80 90 98 87 86 float lastscore lastscore avescore score 6 printf 平均分是 f n lastscore return 0 float avescore float score int len int i float min score 0 float max score 0 float sum 0 0 aver for i 1 i len i if score i max max score i for i 0 i len i sum score i sum sum min max aver sum len 2 return aver 输出结果 85 750000 例随机数按计数输出 include include void array iterate int input array int len int m int output array int main const int len 4 int input array len 3 1 2 4 int m 7 i int output array len array iterate input array len m output array for i 0 i len i printf d output array i return 0 void array iterate int input array int len int m int output array int k 0 int n len int i j 1 while n for i 1 i m i j if j len j 0 while input array j 0 j if j len j 0 m input array j output array k m input array j 0 n 输入 input array len 3 1 2 4 len 4 m 7 输出 2 3 1 4 例统计一个数二进制表达式中 0 的个数 include int fun int a int main int count int a 10 count fun a printf d 中二进制表达式中 0 的个数是 d n a count return 0 int fun int a int count 0 while a if a a a 1 return count 输出结果 10 中二进制表达式中 0 的个数是 2 例镜像翻转二进制表达式 并输出十进制值 include void fun int a int main int a 10 fun a return 0 void fun int a int b 30 int i 0 j int sum 0 while a b i a a a 1 for j 0 j i j sum sum 2 b j printf 翻转后的二进制是 for j 0 j i j printf d b j printf n printf 对应的十进制值是 d n sum 输出结果 翻转后的二进制是 0101 对应的十进制值是 5 例对数组从新一左一右排序 include include void sort int input num int len int output num int main int i const len 7 int input num len 3 6
