How to define the values of n arrays in the C language?

To define the values of n arrays, you can use a loop to assign them one by one. Here is an example code that can dynamically define the values of n arrays:

#include <stdio.h>

int main() {
    int n; // 数组的个数
    printf("请输入数组的个数：");
    scanf("%d", &n);

    int arrays[n]; // 定义包含n个元素的数组

    // 循环赋值
    for (int i = 0; i < n; i++) {
        printf("请输入第%d个数组的值：", i + 1);
        scanf("%d", &arrays[i]);
    }

    // 打印数组的值
    printf("数组的值为：");
    for (int i = 0; i < n; i++) {
        printf("%d ", arrays[i]);
    }

    return 0;
}

In the code above, first the scanf function is used to get the number of elements in the array from the user. Then an array of n elements is defined using int arrays[n]. Next, in a loop, the scanf function is used to get the value of each element in the array from the user and assign it to the corresponding element. Finally, a loop is used to print the values of the array.

Please note that in the C standard, Variable Length Arrays (VLA) were introduced in the C99 standard and not all C compilers support them. If your compiler does not support VLA, you can use dynamic memory allocation to define the values of an array of size n.
