自考新教材--p60_5_2
源程序:
#include <iostream>
#include <string>
using namespace std;
int main()
{
int n,i,length=0;
cout << "输入几个字符串:";
cin >> n;
string *p;
string *A = new string[n];
p = A;
cout << endl;
cout << "请输入:";
for (i = 0; i < n; i++)
{
cin >> A[i];
length = length + A[i].length();
}
p = A; //将指针重新指向数组的首地址
cout << endl;
string max=A[0];
string min = A[0];
for (i = 1; i < n; i++)
{
if (p[i].length() > max.length())
max = p[i];
if (p[i].length() < min.length())
min = p[i];
}
cout << "最长的字符串为:"<<max<<"\n"<<"最短的字符串为:"<<min<<endl;
cout << "字符串的平均长度为:" << length / n << endl;
delete []p;
system("pause");
return 0;
}
运行结果:
