【NOI OpenJudge】【1.1】编程基础之输入输出

01:Hello, World!

#include<iostream>
#include<cstdio>
using namespace std;
int main(){
    printf("Hello, World!");
    return 0;
}

02:输出第二个整数

#include<iostream>
#include<cstdio>
using namespace std;
int main(){
    int a,b,c;
    cin>>a>>b>>c;
    printf("%8d %8d %8d",a,b,c);
    return 0;
}

03:对齐输出

#include<iostream>
#include<cstdio>
using namespace std;
int main(){
    int a,b,c;
    cin>>a>>b>>c;
    printf("%8d %8d %8d",a,b,c);
    return 0;
}

04:输出保留3位小数的浮点数

#include<cstdio>
int main(){
    double x;
    scanf("%lf",&x);
    printf("%.3lf\n",x);
    return 0;
}

05:输出保留12位小数的浮点数

#include<cstdio>
int main(){
    double x;
    scanf("%lf",&x);
    printf("%.12lf\n",x);
    return 0;
}

06:空格分隔输出

#include<cstdio>
int main(){
    char a;
    int b;
    float c;
    double d;
    scanf("%c%d%f%lf",&a,&b,&c,&d);
    printf("%c %d %f %lf", a, b, c, d);
    return 0;
}

07:输出浮点数

#include<cstdio>
int main(){
    double x;
    scanf("%lf",&x);
    printf("%lf\n%.5lf\n%e\n%g\n",x,x,x,x);
    return 0;
}

08:字符三角形

#include<cstdio>
int main(){
    int n = 3;
    char ch;
    ch = getchar();
    for(int i = 1; i <= n; i++){
        int e = i*2-1;
        int blank = (5-e)/2;
        for(int j = 1; j <= blank; j++){
            printf(" ");
        }
        for(int j = 1; j <= e; j++){
            printf("%c",ch);
        }
        printf("\n");
    }
    return 0;
}

09:字符菱形

#include<cstdio>
int main(){
    int n = 3;
    char ch;
    ch = getchar();
    for(int i = 1; i <= n; i++){
        int e = i*2-1;
        int blank = (5-e)/2;
        for(int j = 1; j <= blank; j++){
            printf(" ");
        }
        for(int j = 1; j <= e; j++){
            printf("%c",ch);
        }
        printf("\n");
    }
    for(int i = n-1; i >= 1; i--){
        int e = i*2-1;
        int blank = (5-e)/2;
        for(int j = 1; j <= blank; j++){
            printf(" ");
        }
        for(int j = 1; j <= e; j++){
            printf("%c",ch);
