在c++中生成特定数量的10x10数组中的多个随机字符

#include <iostream>
#include <cstdlib>
#include <ctime>

char generateRandomChar() {
    const char charset[] = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    const int charsetSize = sizeof(charset) - 1;
    return charset[rand() % charsetSize];
}

int main() {
    srand(static_cast<unsigned int>(time(0))); // 设置随机数种子

    const int numRows = 10;
    const int numCols = 10;
    const int numChars = numRows * numCols;

    char array[numRows][numCols];

    for (int i = 0; i < numRows; i++) {
        for (int j = 0; j < numCols; j++) {
            array[i][j] = generateRandomChar();
        }
    }

    // 打印数组
    for (int i = 0; i < numRows; i++) {
        for (int j = 0; j < numCols; j++) {
            std::cout << array[i][j] << " ";
        }
        std::cout << std::endl;
    }

    return 0;
}
