Pascal Yang Hui Triangle Help me see what went wrong with my program

Don't capitalize it, no, it hurts to look at your head.

No single program can achieve unlimited data requirements!!

This program is correct within a certain range of rows.

To print 20 lines, modify as follows:

tab(j * 6 - 5 + n - i) *3); a(i, j);

for tab(j * 8 - 5 + n - i) *4); a(i, j);

Here 6 and 8 are the widths of each data, and 3 and 6 are half of the width of the data.

Later, the number of digits becomes wider, of course, it is not neat, you can get the width of the maximum number before you start filling in the number, and then set this width for each number.

#include

#include ""

int main()

for(i=1;i<=10;i++)

system("pause");

return 0;

3. Ideas.

1：a[0][0] = 1;

a[1][0] = 1;

a[1][1] = 1;

The first 3 elements of the triangle are all 1

2: The elements on the diagonal of the array and the elements in the first column are both 1, so a[i][1] = 1;

a[i][i] = 1;

3：a[i][j] = a[i-1][j-1]+a[i-1][j];

The other elements are equal to the sum of the two elements on the shoulders and good luck!

#include ""

void main()

a[0][0]=1;

int i,j;

for(i=1;i<=9;i++) if(a[i][j]!) from 1=0) is zero and does not output.

printf("%d ",a[i][j]);printf("");

return 0;}

The function main is declared void

So there shouldn't be a renturn 0;

If else typography is also incorrect.

It should be used as much as possible.

if (.else

Array A is also not initialized in the right way.

if(i=j) printf("");The equals of this line should be judged by two equal signs.

Also, you don't assign a boundary of 1 to j==0 and i==j

Then, it seems that if(i=j) printf("");The output return is also not needed.

They lie to you, give it to me.

#include

void main()

while(n<1 ||n>16)

for(i=1;i<=n;i++)

printf("");}

The first loop there should be added:

for(i=0;i<=9;i++)

First of all, you didn't use the recursive implementation, and secondly, your program was wrong.
