错误;“函数定义未声明参数”[已关闭]

问：

我正在尝试编写一个简单的程序，将“Hello”消息写入SDRAM 512MB IC。可悲的是，在尝试编译这个 pogram 时，我偶然发现了这个错误;

“错误：函数定义未声明参数”

似乎说错误出在 writeToIC 命令中，因为 ths 是突出显示的。 由于我对使用 C++ 编程相对较新，有人可以告诉我错误在哪里以及如何修复它吗？

这是完整的程序;

// Including the necessary libraries for GPIO control and exception handling.
#include <iostream>
#include <stdexcept>
    int gpioout = 14;
 
// Function to write a "Hello" message to an SDRAM FBGA-84 SDRAM IC using a digital GPIO pin.
void writeToSDRAM() {
    try {
 
        // Write the "Hello" message to the SDRAM IC.
        writeToIC("Hello");
 
        std::cout << "Message successfully written to SDRAM IC." << std::endl;
    } catch (const std::exception& e) {
        std::cerr << "Error: " << e.what() << std::endl;
    }
}
 
// Unit tests for the writeToSDRAM function.
#include <gtest/gtest.h>
 
/**
 * @namespace SDRAMTest
 * This namespace encapsulates all the unit tests for the SDRAM functions.
 */
namespace SDRAMTest {
 
    /**
     * @class SDRAMWriteTest
     * This class is designed to hold unit tests for the writeToSDRAM function.
     * Every method in this class is a separate test scenario.
     */
    class SDRAMWriteTest : public ::testing::Test {
    protected:
 
        /**
         * Test to check if the "Hello" message is successfully written to the SDRAM IC.
         * @input: None
         * @output: No exceptions are thrown.
         */
        TEST_F(SDRAMWriteTest, TestWriteToSDRAM) {
            EXPECT_NO_THROW(writeToSDRAM());
        }
    };
}
 
int main() {
    // Example: Writing a "Hello" message to an SDRAM FBGA-84 SDRAM IC using a digital GPIO pin.
    writeToSDRAM();
 
    return 0;
}

我一直很困惑，因为我不知道该怎么办。
