删除重复字符

题目1：删除重复字符

例如：zzzgggddes转为zgdes

#include <iostream>
#include <string.h>
using namespace std;

void func(const char *input,char *output)
{
    char repeat=NULL;
    while(*input!='\0')
    {
        if(*input!=repeat)
        {
            *output++=*input;
            repeat=*input;
        }
        input++;
    }
    *output='\0';
}
int main()
{
    char *input="zzzgggddes";
    char *output=new char[strlen(input)+1];
    func(input,output);
    cout<<output<<endl;
    return 0;
}

题目2：识别字符串中的整数并转换为数字形式

void take num(const char *strIn,int *n，unsigned int *outArray)

例如：

输入：strIn="ab00cd+123fght456-25 3.005fgh"

输出: n=6

outArray={0,123,456,25,3,5}

#include <iostream>

using namespace std;

void take_num(const char *strIn,int *n,unsigned int *outArray)
{
    unsigned int sum=0;
    //bool flag=false;
    int i=0;
    while(*strIn!='\0')
    {
        if(*strIn>='0'&&*strIn<='9')
        {
            while(*strIn>='0'&&*strIn<='9')
            {
                sum=sum*10+*strIn-'0';
                strIn++;
            }
            outArray[i++]=sum;
            sum=0;
        }
        else
            strIn++;
    }
    *n=i;
}

int main()
{

    char *strIn="ab00cd+123fght456-25 3.005fghjljk98dd";
    unsigned int outArray[100];
    int n=0;
    take_num(strIn,&n,outArray);
    for(int i=0;i<n;i++)
        cout<<outArray[i]<<' ';
    cout<<'\n'<<n;
    return 0;
}
