用C++打印有趣的模式
这篇文章使用C++编程打印了一个有趣的图案。以下是算法,如下所示
算法
Step-1 Define the size which will be double automatically Step-2 Print the upper section using a loop Step-3 Print the lower section using a loop
示例
根据上述算法,以下c++代码被雕刻成;
#include <iostream> using namespace std; int main(){ int n=3; int i,j; // This is upper half of pattern for (i=1; i<=n; i++){ for (j=1; j<=(2*n); j++){ // Left part of pattern if (i<j) cout<<" "; else cout<<"*"; // Right part of pattern if (i<=((2*n)-j)) cout<<" "; else cout<<"*"; } cout<<endl; } // This is lower half of pattern for (i=1; i<=n; i++){ for (j=1;j<=(2*n);j++){ // Left part of pattern if (i>(n-j+1)) cout<<" "; else cout<<"*"; // Right part of pattern if ((i+n)>j) cout<<" "; else cout<<"*"; } cout<<endl; } return 0; }
在上文中编译代码后,有趣的模式将如下所示打印。
