本文使用C ++编程打印了一个有趣的模式。这是下面的算法
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
基于以上算法,将以下c ++代码刻画为:
#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; }
编译完上面的代码后,有趣的图案将如下所示。
