此代码仅打印数字！我应该怎么打印字符串？！
例如，我用ABC选择5作为长度，输出应该是：
aaaaa
aaaab
aaaac
aaaba
aaabb
aaabc
aaaca
aaacb
aaacc
aabaa
aabab
aabac
aabba
aabbb
aabbc
aabca
aabcb
aabcc
aacaa
aacab
aacac
aacba
aacbb
aacbc
aacca
aaccb
aaccc
abaaa
abaab
abaac
ababa
ababb
ababc
abaca
abacb
abacc
abbaa
abbab
abbac
abbba
abbbb
abbbc
abbca
abbcb
abbcc
abcaa

代码：
#include <stdio.h>
#include <list>
#include <string>
#include <iostream>
using namespace std;
int outputDigit;
string input[1000];
int num;
string final;
int z=0;
struct Generator
{
public:
Generator(int s)
: cSlots(s)
{
a = new int[s];
for (int i = 0; i < cSlots - 1; i++) {
a[i] = 1;
}
a[cSlots - 1] = 0;
nextInd = cSlots;
}
~Generator()
{
delete a;
}
bool doNext()
{
for (;;)
{
if (a[nextInd - 1] == cValues) {
nextInd--;
if (nextInd == 0)
return false;
}
else {
a[nextInd - 1]++;
while (nextInd < cSlots) {
nextInd++;
a[nextInd - 1] = 1;
}
return true;
}
}
}
void doPrint()
{
for (int i = 0; i < cSlots; i++) {
num=a[i];
cout<<num;
}
printf("\n");
}
public:
int *a;
int cSlots;
int cValues;
int nextInd;
};
int main()
{
cout<<"enter outputDigits";
cin>>outputDigit;
Generator g(outputDigit);
while (g.doNext()) {
g.doPrint();
}
return 0;
}
但输出是
enter outputDigits5

cValues是什么？
我知道此答案不会直接给您正确的答案。但是，我建议您确保您：
•初始化构造函数中的所有属性。
•避免使用全局成员。
•使用更具描述性的名称。
•尝试使用较小的输入（例如2或3）首先重现您的错误。
问候，
