## Code for PROGRAM TO EALUATE A POLYNOMIAL WITH N NO.OF PROCESSES USING LOOP SPLITING in C Programming

```#include<stdio.h>
#include<math.h>

main()
{
int coeff[5],x,id,nproc,p,sid,i;
int *poly,sum,j;

poly=(int *)shared(sizeof(int)*2,&sid);

printf("Enter the X: ");
scanf("%d",&x);

printf("Enter the maximum power :");
scanf("%d",&p);

printf("Enter the co-efficients : ");
for(i=1;i<=p;i++)
{
printf("\ncoeff[%d] : ",i);
scanf("%d",&coeff[i]);
}

printf("Enter the no.of proc :");
scanf("%d",&nproc);

id=p_fork(nproc);

for(i=id+1;i<=p;i+=nproc)
{
*(poly+id)=coeff[p-i+1]*(pow(x,i));
}

p_join(nproc,id);
sum=0;
for(i=0;i<p;i++)
{
sum=sum + *(poly+i);
}
for(i=1,j=p;i<=p;i++,j--)
{
if(i==1)
printf("a%d*x%d",i,j);
else
printf(" + a%d*x%d",i,j);
}
printf("\nPolynomial is : %d",sum);
}

OUTPUT

knoppix@ttyp0[pp]\$ cc poly_lps.c
knoppix@ttyp0[pp]\$ ./a.out
Enter the X: 2
Enter the maximum power :3

Enter the co-efficients :
coeff[1] : 1
coeff[2] : 2
coeff[3] : 3

Enter the no.of proc :3
a1*x3 + a2*x2 + a3*x1
Polynomial is : 22```
