input:A row of figures separated by commas

output:A row of figures separated by commas according to the original order.Each number=the original value*the nth time appeared

My answer：

 1 #include<iostream>
 2 #include<string>
 3 #include<array>
 4 #include<cmath>
 5 using namespace std;
 6 
 7 
 8 int main(){
 9 
10     //输入获取 每个输入字符存入字符串inputString
11     string inputString;
12     cin>>inputString;
13     int stringLen=inputString.length();
14     
15     //剔除逗号，逗号之间的数存入数组numArray的每个元素里
16     int *numArray=new int[100]();
17     int numArrayLen=0;
18     
19     int i=inputString.find(",");
20     for(int j=0,jj=i-1;j<i,jj>=0;j++,jj--){
21     numArray[0]+=(inputString[j]-48)*pow(10.0,jj);
22     }
23 
24     inputString[i]=' ';
25     int ii=inputString.find(",");
26     
27     while(ii!=string::npos){
28         numArrayLen++;
29     for(int j=i+1,jj=ii-i-2;j<ii,jj>=0;j++,jj--){
30         numArray[numArrayLen]+=(inputString[j]-48)*pow(10.0,jj);
31     }
32     i=ii;
33     inputString[ii]=' ';
34     ii=inputString.find(",");
35     }
36     
37     numArrayLen++;
38     for(int j=i+1,jj=stringLen-i-2;j<stringLen,jj>=0;j++,jj--){
39     numArray[numArrayLen]+=(inputString[j]-48)*pow(10.0,jj);
40     }
41     
42     //计算每个数的出现次数,并更新数组
43     int *numCount=new int[1000]();
44     for(int j=0;j<=numArrayLen;j++){
45         numCount[numArray[j]]++;
46         numArray[j]*=numCount[numArray[j]];
47     }
48 
49     //按照要求的格式输出
50       for(int j=0;j<numArrayLen;j++)cout<<numArray[j]<<",";
51       cout<<numArray[numArrayLen];
52       
53 }

I did not realize my knowledge was so weak until the test.There are a lot of c++ function that I did not know before or didn't know how to use it well.Consequently,I must still keep fighting harder.By the way ,coding them strengthens my debug aility.F10~~

Ps:It is my first time to write something here in English.

On one hand ,to record a noob who hope to grow into a female geeker on programming.On the other hand,to train my English writing.

Please enlighten.
