VB programming prints n layer pyramid rows Yang Hui triangle

Based on the above, spaces are added to make it look more like a pyramid.

private sub form_click()const n = 10

dim a(n, n) as integerdim i, j as integer

a(1, 1) = 1

a(2, 1) = 1

a(2, 2) = 1

for i = 3 to n

a(i, 1) = 1

a(i, i) = 1

for j = 2 to i - 1

a(i, j) = a(i - 1, j - 1) +a(i - 1, j)

next j, i

for i = 1 to n

print space(2 * n - 2 * i);

for j = 1 to i - 1

print a(i, j);

next j

printnext i

end sub

private sub form_click()dim a() as long, n as long, i as long, j as long, x as long

n = val(

if n > 16 or n <= 0 thenmsgbox "The number is incorrect, and the number of rows is re-entered"

exit sub

end if

redim a(n, n)

for i = 1 to n

for j = 1 to i

if j = 1 or i = j thena(i, j) = 1

elsea(i, j) = a(i - 1, j - 1) +a(i - 1, j)

end if

next j

next i

for i = 1 to n

print spc(48 - 3 * i);

for j = 1 to i

print a(i, j);

x = len(cstr(a(i, j)))if x = 1 then print spc(3);

if x = 2 then print spc(2);

if x = 3 then print spc(1);

next j

Method 3: Define CRT Secure No Warnings 1

#include

int main()

int i,j,n=0;

First, define the two-dimensional array counting symbols i, j and initialize the number of rows in Yang Hui's triangle.

int a[100][100]=;

There are only 2 initial values, i.e., a[0][0]=1 and a[0][1]=2, and the initial values of the rest of the array elements are all 0

The size of the 2D array can be customized, but remember not to make it larger than the size of the integer array.

while(n<1||n>100)

Automatically initialize the issue when the entered value is incorrect, re-entering.

printf("Please enter the number of Yang Hui triangle rows to print":");

scanf("%d",&n);

for(i=1;ifor(j=1;j<=i;j++) The second layer of circular borrowing i limits the number of characters per line.

a[j]=a[i-1][j-1]+a[i-1][j];

for(i=1;ifor(j=1;j<=i;j++)

printf("%5d",a[j]);

printf("");

return 0;

With a dynamic two-dimensional array, two loops are sufficient, assuming that the subscript Wei ij, one number is equal to the sum of the two numbers on his shoulder.
