用C语言打印3块边框的电路板

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

void printCircuitBoard(int width, int height) {
    char** circuitBoard = (char**)malloc(height * sizeof(char*)); // 分配行指针数组
    for (int i = 0; i < height; i++) {
        circuitBoard[i] = (char*)malloc(width * sizeof(char)); // 分配每行的字符数组
    }
    
    // 打印顶部边框
    for (int i = 0; i < width; i++) {
        printf("*");
    }
    printf("\n");
    
    // 打印中间部分
    for (int i = 0; i < height - 2; i++) {
        printf("*");
        for (int j = 0; j < width - 2; j++) {
            printf(" ");
        }
        printf("*\n");
    }
    
    // 打印底部边框
    for (int i = 0; i < width; i++) {
        printf("*");
    }
    printf("\n");
    
    // 释放内存空间
    for (int i = 0; i < height; i++) {
        free(circuitBoard[i]);
    }
    free(circuitBoard);
}

int main() {
    int width = 10;
    int height = 5;
    printCircuitBoard(width, height);
    return 0;
}
