C + + fifth time job

One, array separation

#include <iostream>  using namespace std;  int main ()  {      cout<< "Please enter 10 numbers" <<endl;      int i=0,j=0,k=0,a[10],b[10],c[10];        for (i=0;i<10;i++) cin>>a[i]; for (i=0;i<10;i++)    {          if (a[i]%2==0)          {              b[j]=a[i];              j + +;          }          else          {              c[k]=a[i];              k++;          }      } cout<< "even array is"; for (i=0;i<j;i++) {cout<<b[i]<< "";} cout<<endl;cout<< "Odd Array is"; for (i=0;i<k;i++) {cout<<c[i]<< "";} Cout<<endl;return 0;}

Second, array selection

#include <iostream>  using namespace std;  int main ()  {cout<< "Please enter 10 numbers:" <<endl;int i=0,j=0,k=0,a[10],b[10],c[10];for (i=0;i<10;i++) cin> >a[i];for (i=0;i<10;i++) {for (j=0;j<10;j++) {if (i==j) continue;if (A[i]==a[j]) {b[i]=a[i];b[j]=a[j];}}} cout<< "Non-repeating number:" <<endl;for (i=0;i<10;i++) {if (A[i]==b[i]) continue;c[k]=a[i];cout<<c[k]< < ""; k++;} Cout<<endl;return 0;}

Three, string

#include <iostream> #include <cstdio>  using namespace std;  int main ()  {char str[50];int i=0,j=0,k=0,m=0,n=0;cout<< "input string:"; gets (str); while (str[i]!= ') {if (Str[i] >= ' 0 ' &&str[i]<= ' 9 ') j++;else if (str[i]>= ' a ' &&str[i]<= ' Z ') k++;else if (str[i]>= ' a ' &&str[i]<= ' z ') M++;else n++;i++;} cout<< "The number of numbers is:" <<j<<endl;cout<< "where the number of uppercase letters is:" <<k<<endl;cout<< " The number of lowercase letters is: "<<m<<endl;cout<<" where the number of other characters is: "<<n<<endl;return 0;}
