For example:

At first glance, I thought of printing numbers first and then combining them to form a combination of numbers.

First of all, I wonder if I can use a for loop for control. After all, a number on a computer is composed of plum blossom and space, like this code.

void print1() {    int i, j;    for (i = 0;i < 6; i++)        printf("       *\n");    printf("\n");}void print2() {    int i, j;    for (i = 0; i < 6; i++)        printf("*");    for (i = 0; i < 4; i++) {        printf("\n");        for (j = 0; j < 4 - i; j++)            printf(" ");        printf("*");    }printf("\n");    for (i = 0; i < 6; i++)        printf("*");    printf("\n");}

You can also input and print numbers one by one. However, the combined output of multiple numbers cannot be completed. It can only look at the array, a number is a two-dimensional array, multiple numbers form a three-dimensional array. So the code can be written like this!

#include<stdio.h>#include<string.h>int main(){    char b[100], a[10][5][6] = { ' ', ' ', '*', '*', ' ', ' ', ' ', '*', ' ', ' ', '*', ' ', ' ', '*', ' ', ' ', '*', ' ', ' ', '*', ' ', ' ', '*', ' ',        ' ', ' ', '*', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ',        ' ', ' ', '*', ' ', ' ', ' ', ' ', ' ', '*', '*', ' ', ' ', ' ', '*', ' ', ' ', '*', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ',        ' ', '*', '*', '*', '*', ' ', ' ', '*', '*', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ', '*', '*', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ',        ' ', ' ', '*', '*', '*', ' ',  ' ', '*', ' ', ' ', ' ', ' ',  ' ', '*', ' ', '*', ' ', ' ',  ' ', '*', '*', '*', '*', '*',  ' ', ' ', ' ', '*', ' ', ' ',         ' ', ' ', ' ', '*', ' ', ' ',  ' ','*', '*', '*', ' ', ' ',  ' ', '*', ' ', ' ', ' ', ' ',  ' ', '*', '*', '*', ' ', ' ',  ' ', ' ', ' ', ' ', '*', ' ',         ' ', '*', '*', '*', ' ', ' ',  ' ', ' ', ' *', '*', '*', ' ',  ' ', '*', ' ', ' ', ' ', ' ',  ' ', '*', '*', '*', '*', ' ',  ' ', '*', ' ', ' ', '*', ' ',         ' ', '*', '*', '*', '*', ' ',  ' ', '*', '*', '*', '*', ' ',  ' ', ' ', ' ', ' ', '*', ' ',  ' ', ' ', ' ', ' ', '*', ' ',  ' ', ' ', ' ', ' ', '*', ' ',         ' ', ' ', ' ', ' ', '*', ' ',  ' ', '*', '*', '*', ' ', ' ',  '*', ' ', ' ', ' ', '*', ' ',  ' ', ' ', '*', ' ', ' ', ' ',  '*', ' ', ' ', ' ', '*', ' ',         ' ', '*', '*', '*', ' ', ' ', ' ', '*', '*', '*', ' ', ' ', '*', ' ', ' ', ' ', '*', ' ', ' ', ' ', '*', '*', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ', ' ', ' ', ' ', ' ', '*', ' ' };    int i, j, k, n = 0;    gets_s(b);    n = strlen(b);    for (j = 0; j < 5; j++)    {        for (k = 0; k < n; k++)        {            if (b[k] == '0')            for (i = 0; i < 6; i++)                printf("%c", a[0][j][i]);            if (b[k] == '1')            for (i = 0; i < 6; i++)                printf("%c", a[1][j][i]);            if (b[k] == '2')            for (i = 0; i < 6; i++)                printf("%c", a[2][j][i]);            if (b[k] == '3')            for (i = 0; i < 6; i++)                printf("%c", a[3][j][i]);            if (b[k] == '4')            for (i = 0; i < 6; i++)                printf("%c", a[4][j][i]);            if (b[k] == '5')            for (i = 0; i < 6; i++)                printf("%c", a[5][j][i]);            if (b[k] == '6')            for (i = 0; i < 6; i++)                printf("%c", a[6][j][i]);            if (b[k] == '7')            for (i = 0; i < 6; i++)                printf("%c", a[7][j][i]);            if (b[k] == '8')            for (i = 0; i < 6; i++)                printf("%c", a[8][j][i]);            if (b[k] == '9')            for (i = 0; i < 6; i++)                printf("%c", a[9][j][i]);        }        printf("\n");    }    return 0;    }

The problem is solved !~
