pascal's triangle in c

[ankit_golden]

program in c for pascal's triangle...
i hav read in different books but i cant understand the logic.......
is there any simple logic without pointers and functions
i want a simple program........
can anybody help me out

[priyaraji]

The program to calculate the Pascal triangle is given below:

#include<stdio.h>
#include<conio.h>

void main()
{
int k[10][10];
int i,j,s,l;
printf("How many lines?");
scanf("&#37;d",&l);
k[1][1]=1;
printf("%5d",k[1][1]);
k[2][1]=1;k[2][2]=2;k[2][3]=1;
printf("%d %d %d",k[2][1],k[2][2],k[2][3]);
for(i=3;i<=l;i++)
{
k[i][1]=1;
printf("%d",k[i][1]);
j=2;s=3;
while(j<=i)
{
k[i][j]=k[i-1][s-1]+k[i-1][s-2];
printf("%5d",k[i][j]);
s=s+1;
j=j+1;
}
k[i][j]=1;
printf("%d",k[i][j]);
}
}

Let me know if you are struck with any other programs in C.

sry .. this program is not working....

following code will print this pascal triangle...
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
till n;
where n=limit;;;




#inlcude<conio.h>
#include<stdio.h>

void main()
{
int i,j,n;
printf("Enter the value of n\n");
scanf("%d",&n)
for(i=1;i<=4;i++)
{
for(j=1;j<=i;j++)
{
printf("%d",j);
}
printf("\n");
}
getch();
}





simple change in the for loop will generate the opposite triangle////
54321
4321
321
21
1


for(i=n;i>=1;i--)
{
for(j=1;j<=i;j++)
{

everything remains the same

thx it was very simple plain program
