OpenJudge - NOI - 1.1编程基础之输入输出（C语言 全部题解）

01:Hello, World!

#include 

int main(void)
{
    printf("Hello, World!");
    return 0;
}

02:输出第二个整数

#include 

int main(void)
{
    int a, b, c;
    scanf("%d%d%d", &a, &b, &c);
    printf("%d", b);
    return 0;
}

03:对齐输出

#include 

int main(void)
{
    int a, b, c;
    scanf("%d%d%d", &a, &b, &c);
    printf("%8d %8d %8d", a, b, c);/* 注意输出的格式 */
    return 0;
}

04:输出保留3位小数的浮点数

#include 

int main(void)
{
    float num;
    scanf("%f", &num);
    printf("%.3f", num);/* 注意输出的格式 */
    return 0;
}

05:输出保留12位小数的浮点数

#include 

int main(void)
{
    double num;
    scanf("%lf", &num);
    printf("%.12f", num);/* 注意输出的格式 */
    return 0;
}

06:空格分隔输出

#include

int main(void)
{
    char ch;
    int a;
    float b;
    double c;
    scanf("%c%d%f%lf", &ch, &a, &b, &c);
    printf("%c %d %.6f %.6lf", ch, a, b, c);
    return 0;
}

07:输出浮点数

#include

int main(void)
{
    double num;
    scanf("%lf", &num);
    printf("%f\n%.5f\n%e\n%g", num, num, num, num);/* \n是回车换行符，将当前位置移到下一行开头 */
    return 0;
}

08:字符三角形

#include

int main(void)
{
    char ch;
    scanf("%c", &ch);
    /* 输出空格来代替空白 */
    printf("  %c  \n", ch);
    printf(" %c%c%c \n", ch, ch, ch);
    printf("%c%c%c%c%c\n", ch, ch, ch, ch, ch);
    return 0;
}

09:字符菱形

#include

int main(void)
{
    char ch;
    scanf("%c", &ch);
    /* 输出空格来代替空白 */
    printf("  %c  \n", ch);
    printf(" %c%c%c \n", ch, ch, ch);
    printf("%c%c%c%c%c\n", ch, ch, ch, ch, ch);
    printf(" %c%c%c \n", ch, ch, ch);
    printf("  %c  \n", ch);
    return 0;
}

10:超级玛丽游戏

这道题。。。直接输出就可以了。。。。

#include

int main(void)
{
    printf("                ********\n");
    printf("               ************\n");
    printf("               ####....#.\n");
    printf("             #..###.....##....\n");
    printf("             ###.......######              ###                 ###           ###           ###\n");
    printf("                ...........               #...#               #...#         #...#         #...#\n");
    printf("               ##*#######                 #.#.#               #.#.#         #.#.#         #.#.#\n");
    printf("            ####*******######             #.#.#               #.#.#         #.#.#         #.#.#\n");
    printf("           ...#***.****.*###....          #...#               #...#         #...#         #...#\n");
    printf("           ....**********##.....           ###                 ###           ###           ###\n");
    printf("           ....****    *****....\n");
    printf("             ####        ####\n");
    printf("           ######        ######\n");
    printf("##############################################################              ##################################\n");
    printf("#...#......#.##...#......#.##...#......#.##------------------#              #...#......#.##------------------#\n");
    printf("###########################################------------------#              ###############------------------#\n");
    printf("#..#....#....##..#....#....##..#....#....#####################              #..#....#....#####################\n");
    printf("##########################################    #----------#                  ##############    #----------#\n");
    printf("#.....#......##.....#......##.....#......#    #----------#                  #.....#......#    #----------#\n");
    printf("##########################################    #----------#                  ##############    #----------#\n");
    printf("#.#..#....#..##.#..#....#..##.#..#....#..#    #----------#                  #.#..#....#..#    #----------#\n");
    printf("##########################################    ############                  ##############    ############\n");
    return 0;
}
