1036 跟奥巴马一起编程

#include <iostream>
#include <cmath>
using namespace std;int main() {int n,m;char c;cin>>n>>c;for (int i = 0; i < n; ++i) {cout<<c;}cout<<endl;m= round(1.0*n/2)-2;//round里面不能直接写n/2，因为n/2已经是一个整数了for (int i = 0; i < m; ++i) {cout<<c;for (int j = 0; j < n-2; ++j) {cout<<' ';}cout<<c<<endl;}for (int i = 0; i < n; ++i) {cout<<c;}return 0;
}

输出梯形

#include <iostream>
using namespace std;int main() {int h;while(cin>>h){for (int i = 0; i < h; ++i) {for (int j = 0; j < 2*h-2*(i+1); ++j) {cout<<' ';}for (int j = 0; j < h+2*i; ++j) {cout<<'*';}cout<<endl;}}return 0;
}

Hello World for U

#include <iostream>
#include <cstring>
using namespace std;
const int maxn=81;int main() {char str[maxn];cin>>str;int len= strlen(str);int side=(len+2)/3;int mid=len-side*2;for (int i = 0; i < side-1; ++i) {cout<<str[i];for (int j = 0; j < mid; ++j) {cout<<' ';}cout<<str[len-i-1];cout<<endl;}for (int i = side-1; i <=len-side; ++i) {//一列有side个字符，所以最后一行起始数字的数组下标为side-1//从末尾往前第side个字符的下标是len-sidecout<<str[i];}return 0;
}

等腰梯形

• 注意输出后面的空格
• 注意第一行的空格数是h-1个

#include <iostream>
using namespace std;int main() {int m,h;while(cin>>m){for (int i = 0; i < m; ++i) {cin>>h;for (int k = 0; k < h; ++k) {for (int j = 0; j < h-k-1; ++j) {cout<<' ';}for (int j = 0; j < h+2*k; ++j) {cout<<'*';}for (int j = 0; j < h-k-1; ++j) {cout<<' ';}cout<<endl;}}}return 0;
}

沙漏图形

#include <iostream>
using namespace std;int main() {int n;while(cin>>n){for (int i = 0; i < n; ++i) {for (int j = 0; j < i; ++j) {cout<<' ';}for (int j = 0; j < n-i; ++j) {if(j<n-i-1) cout<<'*'<<' ';else cout<<'*';}cout<<endl;}for (int i = 0; i < n-1; ++i) {for (int j = 0; j < (n-2-i); ++j) {cout<<' ';}for (int j = 0; j < i+2; ++j) {if(j<i+1) cout<<'*'<<' ';else cout<<'*';}cout<<endl;}}return 0;
}
