以下是我模仿其他的程序写的,可运行时总是显示有为

Error executing cl.exe.

我不知道哪里错的,请各位高手给指点一下,谢谢你啊





程序如下:

#include<iostream>
#include<cstring>
using std::cout;using std::cin;using std::endl;

void str_input(char* p1,char* p2)
{
cout<<"string1:";
cin>>p1;
cout<<"string2:";
cin>>p2;
}

void strcmp_put(char* p1,char* p2)
{
cout<<"strcmp():"<<endl;
int result=strcmp(p1,p2);
if(result>0)
cout<<p1<<"greater than"<<p2<<endl;
if(result<0)
cout<<p1<<"less than"<<p2<<endl;
if(result==0)
cout<<p1<<"identical"<<p2<<endl<<endl;
}

void strncmp_put(char* p1,char* p2,size_t count)
{
cout<<"strncmp():"<<endl;
int result=strncmp(p1,p2,count); //strcmp的借口是2个参数，要用strncmp。
if(result>0)
cout<<p1<<" greater than "<<p2<<endl;
if(result<0)
cout<<p1<<" less than "<<p2<<endl;
if(result==0)
cout<<p1<<" identical to "<<p2<<endl<<endl;
}

void main()
{
char str1[80],str2[80],p;
int i;

for(i=1;i<=3;i++)
{
str_input(str1,str2);
strcmp_put(str1,str2);
//strcmp_put(str1,str2); 这一句和上面的重复了，没用。
strncmp_put(str1,str2,3); //这里也不小心写掉了！
cout<<"-------------------"<<endl;
}
}
