使用 c 进行矩阵加法

Question

我正在分配使用 C 添加矩阵的任务，我使用的是 Dev C++ IDE 版本 5.71，我尝试使用此代码但它没有编译

#include "stdio.h"

int main(){
    int a, b ,c ,d, mat1[20][20],mat2[20][20], matAdd[20];

    //a = row number ,b = column no 
    printf("Enter the number of rows and columns:\n");

    scanf("%d%d", &a,&b);

    printf("Enter elements of matrix one:\n");

    for (c =0; c < a; c++){
        for (d=0; d < b; d++){
            scanf("%d", &mat1[c][d]);
         }
    }
    printf("Enter elements of matrix two:\n");

    for (c =0; c < a; c++){
        for (d = 0; d < b; d++){
            scanf("%d", &mat2[c][d]);
        }
    }

    printf("Addition of the two matrices is below:\n");

    for (c =0; c < a; c++){
        for (d=0; d < b; d++){

        matAdd[c][d] = mat1[c][d] + mat2[c][d]; 
        printf("%d\t",matAdd[c][d]); 
    }
    printf("%n");
    getch();
    return 0 ;
}

这是我收到的错误。

Line:35 Col:12 [Error] subscripted value is neither an array nor pointer nor vector
Line:36 Col:26 [Error] subscripted value is neither an array nor pointer nor vector
Line:45 Col:1 [Error] expected declaration or statement at end of input

有一个错字：你的定义 matAdd[20] 应该是 matAdd[20][20]。
