Hi Friend,

Try the following code:

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

void main(){

int a[15][15],i,j,rows,num=25,k;
printf("\n enter the number of rows:");
scanf("%d",&rows);
for(i=0;i<rows;i++){
for(k=num-2*i;k>=0;k--)
printf(" ");
for(j=0;j<=i;j++){
if(j==0||i==j){
a[i][j]=1;
}
else{
a[i][j]=a[i-1][j-1]+a[i-1][j];
}
printf("%4d",a[i][j]);
}
printf("\n");
}
getch();
}

Thanks

printf("using only one dimensional array") ;

int n1  = (rows * (rows+1))/2 ;
int b[n1];
int p = 1;

for(int i = 0 , j = 0 ; i < n ; ++i , ++j)
{
    int k = i+j ;

    b[j] = 1 ;
    //printf("%d",b[j]);

    if(j < k )
    {
        ++j ;

        while(j < k)
        {
            b[j] = b[p] + b[p + 1] ;
            //printf("\t%d",b[j]);
            ++j ;
            ++p;
        } 
        b[j] = 1 ;

Pascals triangle using 1D array

    int n1  = (rows * (rows+1))/2 ;
    int b[n1];
    int p = 1;

    for(int i = 0 , j = 0 ; i < n ; ++i , ++j)
    {
        int k = i+j ;

        b[j] = 1 ;
        //printf("%d",b[j]);

        if(j < k )
        {
            ++j ;

            while(j < k)
            {
                b[j] = b[p] + b[p + 1] ;
                //printf("\t%d",b[j]);
                ++j ;
                ++p;
            } 
            b[j] = 1 ;
            //printf("\t%d"b[j]);
            if( i > 1)
                ++p;

        }
    //printf("\n");
    }
