整数与字符串转换

#include <iostream>#include <vector>using namespace std;#define MaxNum 20int main(){//下面是整数转为字符串；int data;cout<<"please input your int data"<<endl;cin>>data;if(!cin) return 1;int i=0,j=0,temp;    char str[MaxNum],str1[MaxNum];while(temp=data%10){str[i]=temp+'0';data/=10;i++;}j=--i;i=0;while(j>=0){str1[i]=str[j];i++;j--;}str1[i]='\0';cout<<str1<<endl;//下面是字符串转为整数cout<<"please input your string"<<endl;cin>>str;if(!cin) return 0;i=0,temp=0;while(str[i]!=NULL){temp=temp*10+(str[i]-'0');i++;}cout<<temp<<endl;}
