1,使用字符数组存储一段字符，判断是否是回文字符串（需要判断并忽略空格）

#include<iostream>
#include<cstring>
using namespace std;
void re(char *s){//逆置数组
    int len = strlen(s);
    for(int i=0;i<len/2;i++){
        swap(s[i],s[len-i-1]);
    }
}
bool huiwen(char *s){
    char * temp ;
    temp = new char[strlen(s)+1];//整个新的数组存
    strcpy(temp,s);//记得拷贝过来
    re(s);
    int len = strlen(s);
    int i = 0;
    while(i<len){
        if(s[i]!=temp[i]){
             return false;
        }
       i++;
    }
    return true;
}
int main(){
    char a[]= "i am a i";
    char b[] ="aba";
    cout<<huiwen(a)<<endl;
    cout<<huiwen(b)<<endl;

    return 0;
}

2,输入一行字符串，判断字符串出现的单词有多少个字母

#include<iostream>
#include<cstring>
using namespace std;
int main(){
    char str[] = "my name is xiao ming";
    char *token;
    token = strtok(str," ");
    while(token!=NULL){
        cout<<token<<" "<<strlen(token)<<endl;
        token = strtok(NULL," ");
    }
    return 0;
}
