小明和小亮玩报数游戏，小明从1到5报数（即报1 2 3 4 5），小亮从1到10报数（即报1 2 3 4 5 6 7 8 9 10）。若两人同时开始，并以同样的速度报数，不停重复。当两人都报了100个数时，编程计算，两个人同时报相同数的次数是多少。#include<iostream> using namespace std;int main() { int h,m,n,i=0,x=0; do { m=i%5+1; h=i%10+1; if(m==h)x++;

主要是核心算法，多维与一维的坐标转换，已经注释#include<iostream>using namespace std;void main(){ int array1[3][4] = { {1,2,3,4},{5,6,7,8},{9,10,11,12} }; int array2[12] = { 0 }; int row, col, i; cout <&l...

如果指针变量p已指向数组中的一个元素，则p+1指向同一数组的下一个元素#include<iostream>using namespace std;void main(){ int i, a[10]; int* p; //利用循环，分别为10个元素赋值 for (i = 0; i < 10; i++) a[i] = i; //将数组中的10个元素输出到显...

简单的用指针实现两个数的大小比较，将a的值赋予指针*p1，将b的值赋予指针*p2#include<iostream>#include<iomanip>using namespace std;void main(){ int* p1, * p2; int* p; int a, b; cout << "Input a:" << e...

打印字符串的时候未加结束符会出现乱码，加上就不后了。#include<iostream>using namespace std;void main(){ int i; char array[12]; array[0] = 'a'; array[1] = 'b'; array[2] = '\0'; printf("%s\n", array);}...

定义了一个静态变量，每次调用函数add时，静态变量n都保存了前次被调用的值，所以输出的是累加和。#include <iostream>using namespace std;int add(int x){ static int n = 0; n = n + x; return n;}void main(){ int i, j, sum; cout &...
