在数组中使用malloc时输出错误

Question

我对c很新，而我正在尝试做的是学习并使用malloc和realloc。我的程序采用整数x输入，然后循环直到满足x，同时还采用其他整数输入。然后我做了各种计算。但是当我知道它应该是别的东西时，我的输出是0。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>

int main(void)
{

    calculations();
}

void calculations()
{

    int i;
    int x;
    int total = 0;
    double squareRoot;
    double overall;

    scanf("%d", &x);

    int* array = malloc(x * sizeof(int));

    if (!array) {
        printf("There isn't enough memory \n");
        return;
    }

    int c = 0;


    while (c < x) {


        scanf("%d", &array[c]);

        total += array[c] * array[c];
        c++;
    }

    squareRoot = sqrt(total);
    array = realloc(array, x * sizeof(int));

    int b = 0;

    while (b < x) {

        overall = array[c] / squareRoot;
        printf("%.3f ", overall);

        b++;
    }
}
