初始化矩阵，预计前$ P在C $ pssion错误 [英] initializing a matrix, expected expression error in C

问题描述

所以我试图查找似乎有帮助，但最终并没有几件事情。

So I have tried looking up a few things that seemed helpful, but ultimately were not.

我应该初始化一个6×8矩阵作为一个独立的功能的二维数组。我有三个文件，主功能文件，一个功能文件，和一个头文件。

I am supposed to initialize a 6x8 matrix as a 2D array in a separate function. I have three files, a main function file, a functions file, and a header file.

下面是相关主要code

Here is relevant code from main

     int plate[MAX_ROWS][MAX_COLS];

double A = 0, B = 0, T1 =0, T2 = 0, C = 0;

printf("\n");
printf("Welcome to the Heat Plate Simulation\n\n");
printf("Enter: Heat-A, Heat-B, Plate-1, Plate-2, Stab-Crit\n\n");
scanf("%lf%lf%lf%lf%lf", &A,&B,&T1,&T2,&C);

然后我尝试

    initialize_plate(plate,T1, T2);

都到

    void initialize_plate(int plate[][MAX_COLS],double T1, double T2)
    {
 plate[MAX_ROWS][MAX_COLS] = {
    { T1, T1, T1, T2, T2, T2},
    { T1, T1, T1, T2, T2, T2},
    { T1, T1, T1, T2, T2, T2},
    { T2, T2, T2, T1, T1, T1},
    { T2, T2, T2, T1, T1, T1},
    { T2, T2, T2, T1, T1, T1} 
    };
return;
    }

我收到的错误是7P_functions.c：14：32：错误：预期前$之前'{'令牌p $ pssion
   *板[MAX_ROWS] [MAX_COLS] = {

The error I receive is 7P_functions.c:14:32: error: expected expression before ‘{’ token *plate[MAX_ROWS][MAX_COLS] = {

鉴于我已经研究这个错误我唯一的猜测是，它是与阵列已经被初始化，但我不知道如何，而如果我初始化函数，而不是在内部数组纠正这个问题主要不只是成为一个局部变量？

Given what I have researched with this error my only guess is that it has something to do with the array already being initialized, but I am not sure how to rectify this problem whereas if I initialize the array within the function and not in main doesn't it just become a local variable?

任何帮助将是非常美联社preciated。

Any help would be much appreciated.

推荐答案

设置使用值的memcpy 从临时数组。

Set the value using memcpy from the temporary array.

void initialize_plate(int plate[][MAX_COLS],double T1, double T2){
    memcpy(plate, (int [][MAX_COLS]){
        { T1, T1, T1, T2, T2, T2},
        { T1, T1, T1, T2, T2, T2},
        { T1, T1, T1, T2, T2, T2},
        { T2, T2, T2, T1, T1, T1},
        { T2, T2, T2, T1, T1, T1},
        { T2, T2, T2, T1, T1, T1} },
        6*sizeof(int [MAX_COLS]));

    return;
}
