以下是输出杨辉三角形的 Python 代码:
```python
n = 10 # 输出行数
triangle = [[1] * (i+1) for i in range(n)] # 初始化杨辉三角形
# 计算杨辉三角形中每个数的值
for i in range(2, n):
for j in range(1, i):
triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j]
# 输出杨辉三角形
for row in triangle:
print(' '.join(map(str, row)))
```
输出结果为:
```
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
1 8 28 56 70 56 28 8 1
1 9 36 84 126 126 84 36 9 1
```

Sure, I can help you with that. Here's the code in C language to print the first 7 rows of the Pascal's triangle:
```c
#include <stdio.h>
int main() {
int n = 7;
int a[n][n], i, j;
for (i = 0; i < n; i++) {
for (j = 0; j <= i; j++) {
if (j == 0 || j == i) {
a[i][j] = 1;
} else {
a[i][j] = a[i-1][j-1] + a[i-1][j];
}
printf("%d ", a[i][j]);
}
printf("\n");
}
return 0;
}
```
I hope that helps! Let me know if you have any other questions.
6.C语言输出以下的杨辉三角形(要求输出10行)。 1 1+1 1+2+1 1+3+3+1 1+4+6+4+1 1+5+10+10+5+1 ………………
以下是C语言输出10行杨辉三角形的代码:
```c
#include <stdio.h>
int main() {
int a[10][10];
int i = 0, j = 0;
//先给第一列(j=0)和对角线的数据赋值(都为1)
for (i = 0; i < 10; i++) {
a[i][i] = 1;
a[i][0] = 1;
}
//再从第三行开始赋值
for (i = 2; i < 10; i++) {
for (j = 1; j <= i - 1; j++) {
a[i][j] = a[i - 1][j - 1] + a[i - 1][j];
}
}
//输出
for (i = 0; i < 10; i++) {
for (j = 0; j <= i; j++) {
printf("%6d", a[i][j]);
}
printf("\n");
}
return 0;
}
```
