一、数组分离

#include<iostream>
using namespace std;
int main()
{
    int a[10],b[10],c[10],i,j=0,k=0;
    cout<<"请输入十个数字:";
    for(i=0;i<10;i++)

		{
			cin>>a[i];
           if(a[i]%2==0)
           {
			   b[j++]=a[i];
          }
		  else
		  {
			  c[k++]=a[i];
          }
      	}
      	 cout<<"该数组中偶数有:"<<endl;
      	 for(i=0;i<j;i++)
         {
             cout<<b[i]<<" "<<endl;
         }
      	  cout<<"该数组中奇数有:"<<endl;
      	  for(i=0;i<k;i++)
         {
             cout<<c[i]<<" "<<endl;
         }
  return 0;
}

#include<iostream>
using namespace std;
int main()
{
    int a[10],sum1=0,sum2=0,i;
    cout<<"请输入十个数字："<<endl;
    for(i=0;i<10;i++)
    {
        cin>>a[i];
        if(a[i]>0)
        sum1=a[i]+sum1;
        else
        sum2=a[i]+sum2;
    }
cout<<"数组中正数的和:"<<sum1<<endl;
cout<<"数组中负数的和:"<<sum2<<endl;
return 0;
}

<pre name="code" class="cpp">#include<iostream>
#include<cstdio>
using namespace std;
int main()
{
   char str[50];
   int i=0,j=0,k=0,n=0;
	cout<<"输入字符串:";
	gets(str);
	while(str[i]!='\0')
	{
		if(str[i]>='0'&&str[i]<='9')
        {
        j++;

        {
        k++;
		i++;
        }
		else
        {
        n++;
		i++;
        }
	}
  cout<<"其中的数字个数是: "<<j<<endl;
  cout<<"其中的字母个数是: "<<k<<endl;
  cout<<"其中的其它字符个数是: "<<n<<endl;
return 0;
