    program error

    Code:
    I am 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 } token
    project1.c:24: error: expected ; 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;
    }

    Look closely at the following snippet:
    Code:
            while((h*((i*i)+(counter*counter))/N) <= N){
                    for(i=a; i<=b; i++)
                            for(counter=a; counter=b; counter++)
                    }
    What is the purpose of that last loop? It appears to be missing it's body. It also looks malformed. Why are you assigning a value in the compare section.

    Also this looks more like a C question than a C++ question and should have been posted in the C forum.
