How do you initialize an array in C code example

Example 1: array value from user c

#include <stdio.h>
int main(void)
{
int size, i;
printf("Enter the size of the arrays:\n");
scanf("%d", &size);

int arr1[size];
printf("Enter the elements of the array:\n");
for (i = 0; i < size; i++) {
    scanf_s("%d", arr1[size]);
}
printf("The current array is:\n %d", arr1[i]);
}

Example 2: c array initialization

int x[] = {1,2,3}; // x has type int[3] and holds 1,2,3
int y[5] = {1,2,3}; // y has type int[5] and holds 1,2,3,0,0
int z[3] = {0}; // z has type int[3] and holds all zeroes

Example 3: how to initialize an array in c

double balance[5] = {1000.0, 2.0, 3.4, 7.0, 50.0};
