在字符串中找出连续最长的数字串

#include<iostream>#include<cctype>unsigned int Continumax(char**, char*);using namespace std;const int MAX = 1000;int main(){char* str = new char[MAX];cin.getline(str, MAX);char** p = new char*[MAX];unsigned int n = Continumax(p,str);cout<< *p << ','<< n << endl;delete[] p;delete[] str;return 0;}unsigned int Continumax(char** pOutputstr, char* intputstr){int a[MAX] = { 0 };int t = 0;int i = 0;char* p[MAX];while (i<=strlen(intputstr)){bool b1 = isdigit(intputstr[i]);if (b1){p[t] = intputstr + i;a[t] = i;for (int j = i + 1;; j++){bool b2 = isdigit(intputstr[j]);if (!b2){a[t] = j - a[t];i = j + 1;t++;break;}}}elsei++;}int temp = a[0];int n = 0;for (int k = 1; k < t; k++){if (a[k]>temp){temp = a[k];n = k;}}*pOutputstr = p[n];return a[n];}

计算日期到天数转换

#include<iostream>int iConverDateToDay(int year,int month,int day);int Param;using namespace std;int main()  {  int year,month,day;cin>>year;cin>>month;cin>>day;int n=iConverDateToDay(year,month,day);if (n==-1){cout<<"-1";}else{cout<<Param;}return 0;  }  int iConverDateToDay(int year, int month, int day){int y;  int z;int sum=0;if(year<0||year>9999)  {  return -1;  }   if(month>12||month<0)  {  return -1;  }  else  {  if((year%4==0&&year%100!=0)||year%400==0)  {  int a1[13]={0,31,29,31,30,31,30,31,31,30,31,30,31};  for(int i=0;i<month;i++)  sum+=a1[i];  }  else  {  int a2[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};  for(int i=0;i<month;i++)  sum+=a2[i];  }  y=sum;  }  if(day<0)  {  return -1;  }   else   {  if(month==1||month==3||month==5||month==7||month==8||month==10||month==12)  {  if(day>31)  {  return -1;  }  }  else if (month==4||month==6||month==9||month==11)  {  if(day>30)  {  return -1;  }  } if((year%4==0&&year%100!=0)||year%400==0)  {  if(month==2)  {  if(day>29)   {  return -1;  }  }  }  else  {  if(month==2)  {  if(day>28)   {  return -1;  }  }  }  }  z=day;Param=y+z;  return 0;}

找出字符串中第一个只出现一次的字符

#include <iostream>bool FindChar(char* pInputString, char* pChar);const int MAX = 1000;int main(){using namespace std;char* str = new char[MAX];cin.getline(str, MAX);char* pChar = new char;FindChar(str,pChar);cout<<*pChar<<endl;delete pChar;delete[]str;return 0;}bool FindChar(char* pInputString, char* pChar){int i=0;int m;int n=strlen(pInputString);while (i<n){ m=0;for(int j=0;j<n;j++){*pChar=pInputString[i];if (pInputString[j]==* pChar&&j!=i){m=1;break;}}if (m==0) break;i++;}if (m==1){* pChar='.';}return 0;}
