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。
解析:
#include <iostream>
using namespace std;
#include <string>
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;
}
}
