Pascal's Triangle is a triangle where all numbers are the sum of the two numbers above it. Here's an example of the Pascal's Triangle of size 5.
Example: how to find the ith row of pascal's triangle in c
#include <stdio.h>
#include <stdlib.h>
int main()
{
int N;
scanf("%d", &N);
int pascalArray[N + 1][N + 1];
int i, j;
if(0 <= N && N <= 20)
{
for (i = 0; i < N + 1; i++)
{
for(j = 0; j <= i; j++)
{
if(j == 0 || j == i)
pascalArray[i][j] = 1;
else
pascalArray[i][j] = pascalArray[i-1][j-1] + pascalArray[i-1][j];
if (i == N)
printf("%d ", pascalArray[i][j]);
}
}
}
return 0;
}
