Code:

new to programming in c and my task is to write a simple program that is able to compute the area under a curb using the trapezoidal rule. I wrote the program but it will not compile, the error I m getting is:
 
 expected expression before â}â token
project1.c:24: error: expected â;â before numeric constant
 
and this are my codes:
 
#include <stdio.h>
int main(void)
{
         int a, b, N,h,i,counter,A;
        
 printf(" enter the interval a and b");
 scanf("%d\n%d\n", &a, &b);
        
 prinf("enter the number of trapezoids you would like to  use");
        scanf("%d\n", &N);
        
 h= (b-a)/N;
        
 while((h*((i*i)+(counter*counter))/N) <= N){
                  for(i=a; i<=b; i++)
                           for(counter=a; counter=b; counter++){
       A=(h*((i*i)+(counter*counter))/2);
        }

printf("the area under the curb from %d to %d is: %d", a, b, A);
        
counter 0;
}
