1.三角形

#include <iostream>
using namespace std;
int main() {
    int t;
    cin>>t;
    int n = 65;
    for(int i = 1;i<=t;i++){
        for(int j = 1;j<=t-i;j++){
            cout<<" ";
        }
        for(int j = 1;j<=i*2-1;j++){
            cout<<char(n);
            n++;
        }
        cout<<endl;
        n = 65;
    }
    return 0;
}

2.菱形

#include <iostream>
using namespace std;
int main() {
    int t;
    cin>>t;
    int n = 65;
    int a = (t/2+1)*2;
    for(int i = 1;i<=t;i++){
        for(int j = 1;j<=t-i;j++){
            cout<<" ";
        }
        for(int j = 1;j<=i*2-1;j++){
            cout<<char(n);
            n++;
        }
        cout<<endl;
        n = 65;
    }
    for(int i = t-1;i>=1;i--){
        for(int j = 1;j<=t-i;j++){
            cout<<" ";
        }
        for(int j = 1;j<=i*2-1;j++){
            cout<<char(n);
            n++;
        }
        cout<<endl;
        n = 65;
    }
    return 0;
}

3.两个等腰直角三角形拼成的图形

#include <iostream>
using namespace std;
int main() {
    int t;
    cin>>t;
    int n;
    for(int i = t;i>=1;i--){
        n = 65;
        for(int j = 1;j<=t-i;j++){
            cout<<" ";
        }
        for(int j = 1;j<=t;j++){
            if(j==i){
                cout<<"|";
                n++;
                continue;
            }
            cout<<char(n);
            n++;
        }
        cout<<endl;
    }
    return 0;
}
