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; }
