Question

用c语言程序输出以下图案： 1 222 33333 4444444 555555555 6666666 77777 888 9

Answer 1

应该菱形吧，LS仁兄只输出前半部分而已

#include <stdio.h>
#include "math.h"
#define n 9
void main()
{
int i,j,mid;
mid=n/2+1;
for(i=1;i<=n;i++)
{
for (j=1;j<=abs(i-mid);j++)printf(" ");//输出前缀空格
for(j=1;j<=2*(mid-abs(i-mid))-1;j++)printf("%d",i);//输出i
printf("\n");//换行
}
}

Answer 2

#include<stdio.h>
#define n 5
int main()
{
int i,j;
for(i=1;i<=n;i++)
{
for(j=1;j<=n-i;j++)
printf(" ");
for(j=1;j<=2*i-1;j++)
printf("%d",i);
printf("\n");
}
}

Answer 3

ck()
For i = 1 To 9
Print Tab(10 - i);
For j = 1 To i * 2 - 1
Print CStr(10 - i);
Next
Print
Next
End Sub
