Hi,

I've got this homework:

Write a program that calculates the Root-Mean-Square (RMS) of a

sequence of numbers whose length and content are determined by the

user. The RMS calculation should be done in a function of prototype

double RMS(double *x, int N), where N is the number of elements

in the array x. Demonstrate its use in a main function which prompts

the user for the length of the sequence, and then the values of this

sequence.

And I've got that far:

Code:

#include <stdio.h>
#include <math.h>
double RMS(double *x, int N)
{
float rms;
int i;
for (i=0; i<N; i++) {
rms=sqrt(x[N^2]);
}
return rms;
}
int main()
{
int i, N;
float rms;
printf("Please enter the length of the sequence:\n");
scanf("%d", &N);
double x[N];
for (i=0;i<N;i++){
printf("Please enter the values:\n", i+1);
scanf("%d", &x[N]);
}
rms=RMS(x,N);
printf("%f", rms);
return0;
}

It doesn't give me any errors but neither does it work.. Can someone please tell me if I'm on the right track?

Thanks
