对于一个任意输入的少于200字节的字符串，把它按‘-’分成若干子串（子串最多20个），输出原始字符串和每个子串，要求能依次处理用户输入的多个字符串，直到用户输入字符串“0”时程序退出。
#include
using namespace std;
#include
void main()
{
char str_s[200];
char *ptr = str_s;
char *pt = str_s;
int lenth;
cout << "please input the source string you want to deal with:" << endl;
while ( true )
{
gets( str_s );
lenth = strlen( str_s );
char *ptr = str_s;
char *pt = str_s;
if ( str_s[0] == '0' )
{
break;
}
int flag = 0, length = 0;
if ( lenth < 200 )
{
while ( *ptr != '\0' && length <= lenth )
{
cout << *ptr;
ptr++;
length++;
}
cout << endl;
while ( *pt != '\0' && flag <= 20 )
{
if ( *pt != '-' )
{
cout << *pt;
pt++;
}else {
flag++;
pt++;
cout << endl;
}
}
cout << endl;
}
cout << "please input the source string you want to deal with:" << endl;
}
}
