这里：
```cpp
for (a = 0; a < n - i; a++)
{
printf(" ");
count++;
}
```
当你三角形枚举到最后一行的时候，```count``` 会少加1。
例：
```
输入;
5
输出:
0102030405
0607080910
1112131415
1617181920
2122232425
01
0203
040506
07080910
1011121314

噢，不是 ```count``` 少加一，是 ```b``` 少加一

你完全可以这样写：
```cpp
#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
void Square(int n)
{
for (int i = 1; i <= n * n; i++)
{
if (i <= 9)
{
printf("%d%d", 0, i);
}
if (i > 9)
{
printf("%d", i);
}
if (i % n == 0)
{
printf("\n");
}
}
}
void Triangle(int n)
{
int a = 0;
int b = 1;
int count = 0;
for (int i = 1; i <= n; i++)
{
for (a = 0; a < n; a++)
{
if(a<n-i) printf(" ");
else if(b<10) printf("%d%d",0,b++);
else printf("%d",b++);
}
puts("");
}
}
int main()
{
int n = 0;
scanf("%d", &n);
Square(n);
printf("\n");
Triangle(n);
return 0;
}
```

```c
#include<stdio.h>
int main(){
int n;
scanf("%d",&n);
int t=1;
for(int i=0;i<n*n;i++)
{
printf("%02d",t);
if((i+1)%n==0)
{
printf("\n");
}
t++;
}
printf("\n");
int c=1;
for(int i=0;i<n;i++)
{
for(int j=0;j<(n-i-1)*2;j++)
{
printf(" ");
}
for(int j=0;j<i+1;j++)
{
printf("%02d",c);
c++;
}
printf("\n");
}
return 0;
}
```

@[One_JuRuo](/user/86507) 请问#define _CRT_SECURE_NO_WARNINGS是什么意思a
by NGM123 @ 2023-09-29 18:49:45
@[NGM123](/user/882629) 我直接复制楼主代码改的，没注意到，我也不清楚。不过，我认为你可以先 [bdfs](https://blog.csdn.net/aa804738534/article/details/115234797)。
