C++作业5

项目二
#include<iostream>
using namespace std;
int main()
{
int A[10],B[10],i,j=0,k=0,p=0;
cout<<"请输入10个数判断其中的不重复数："<<"\n";

}

}

}
cout<<"不重复的值有：";
for(i=0;i<p;i++)
cout<<B[i]<<" ";
cout<<endl;

return 0;
}

项目四
#include<iostream>
#include<cstdio>
using namespace std;
int main()
{
char str[50];
int i=0,n=0,j=0,k=0;
cout<<"输入字符串:";
gets(str);

else
k++;
i++;
}
cout<<"数字个数是: "<<n<<"\n";
cout<<"字母个数是: "<<j<<"\n";
cout<<"其他字符个数是: "<<k<<endl;

return 0;
}

项目五：
#include<iostream>
using namespace std;
int main()
{
const int N=5;
int A
,sum1=0,sum2=0,i;
cout<<"请输入10个数："<<"\n";
for(i=0;i<N;i++)
cin>>A[i];
for(i=0;i<N;i++)
{
if(A[i]>0)
sum1=sum1+A[i];
else if(A[i]<0)
sum2=sum2+A[i];
else
cout<<"error"<<"\n";

}
cout<<"整数的和为："<<sum1<<"\n"<<"负数的和为："<<sum2<<endl;

return 0;

}
