项目二：数组分离

#include<stdio.h>#include<iostream>using namespace std;int main(){bool m;int a[10], b[10], i, j, k = 0, n = 0;cout << "请输入10个数：";for (i = 0; i < 10; i++)cin >> a[i];{for (i = 0; i < 10; i++){m = 1;for (j = 0; j < 10; j++){if (i == j)continue;if (a[i] == a[j])m = 0;}if (m){b[k] = a[i], n++, k++;}}cout << "a[10]";for (i = 0; i < 10; i++){cout << a[i] << " ";}cout << endl;cout << "b[n]";for (n = 0; n < k; n++){cout << b[n] << " ";}cout << endl;system("pause");return 0;}}

项目四：字符串

#include<stdio.h>#include<iostream>  #include<cstdio>    using namespace std;int main(){char str[50];int i = 0, n = 0,m=0,j=0,k=0;cout << "输入字符串:";gets_s(str);while (str[i] != '\0'){if (str[i] >= '0'&&str[i] <= '9') n++;else if (str[i] >= 'A'&&str[i] <= 'Z')m++;else if (str[i] >= 'a'&&str[i] <= 'z')j++;else k++; i++;}cout << "其中的数字个数是: " << n << endl;cout << "其中大写字母的个数是：" << m << endl;cout << "其中小写字母的个数是：" << j << endl;cout << "其中其他字符的个数是：" << k << endl;system("pause");return 0;}
