Question

用C/C++实现字符串的创建,并进行查找与替换

Answer 1

//用标准库，很简单，一看就明
#include
<iostream>
#include
<string>
#include
<vector>
using
namespace
std;
int
main()
{
int
strMax
=
0;
string
str;
cout
<<
"字符串数目:
"
<<
ends;
cin
>>
strMax;
vector<string>
vecStr;
for
(int
i
=
0;
i
!=
strMax;
++i)
{
cin
>>
str;
vecStr.push_back(str);
}
cout
<<
"查找串:
"
<<
ends;
cin
>>
str;
bool
sign
=
false;
vector<string>::iterator
iter;
for
(iter
=
vecStr.begin();
iter
!=
vecStr.end();
++iter)
{
if
(*iter
==
str)
{
cout
<<
"串
"
<<
str
<<
"找到."
<<
endl;
cout
<<
"替换串为:
"
<<
ends;
cin
>>
str;
*iter
=
str;
sign
=
true;
}
}
if
(sign
==
false)
cout
<<
"找不到串:
"
<<
str
<<
endl;
else
for
(iter
=
vecStr.begin();
iter
!=
vecStr.end();
++iter)
{
cout
<<
*iter
<<
endl;
}
return
0;
}
