正整数转换成字符串

#include <iostream>using namespace std;class STR{int num;char s[15];public:STR(int x){num =x;}void itoa();void print(){cout<<"n="<<num<<endl;cout<<"string = "<<s<<endl;}};void STR::itoa(){int i =0;int x =num;while(x){s[i] = x%10 + '0';//cout<<s[i]<<endl;x = x/10;i++;}s[i]='/0';int n = i-1;for(i=0;i<=n/2;i++){char c;c=s[i];s[i]=s[n-i];s[n-i] = c;}}int main(){int n;cout<<"input a num? ";cin>>n;STR str(n);str.itoa();str.print();return 0;}
