Question

My Instructions: Write a program that starts out asking the user for the mean u and standard deviation s for the normal distribution (see the wiki article )

The program then asks for an N, and then asks for N values x. For each x it writes out f(x) to the screen. Note that the program asks the user for u, s, and N just once. After that it asks for N values for x, one by one. After each value x it writes out the corresponding value of the function.

What I am confused about is what the N is supposed to stand for. I assumed it was number of x’s but can anyone clarify this for me?

#include <stdio.h>
#define _USE_MATH_DEFINES 
#include <math.h>
#include <stdlib.h>

int main()
{
double u,s, N, x1,math1, math2, math3,n, v, x;

printf("Enter Mean: ");
scanf("%lf", &u);
printf("Enter Standard Deviation: ");
scanf("%lf", &s);
printf("Enter number of x's: ");
scanf("%lf", &N);

    for (v=1; v<=N; v++)
    {
    printf("Enter Value: ");
    scanf("%lf", &x);
    n=(-1/2);
    printf("f(x)= ");
    math1 =1/(u*sqrt(2*M_PI));
    math2= (x-u)/s * (x-u)/s;
    math3= M_E * exp(n);
    x1 = math1 * exp(math3)*exp(math2);
    printf("%lf  \n", x1);
    }
system("Pause");
}

Answer 1

N stands for number of inputs

pretty much clear from this part:
for (v=1; v<=N; v++)
