In C language, how to connect a module that stores data and a module that outputs data

the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > in order to implement will be deposited in the data module and output module, need to store the data in a variable, This variable is then passed into the module that outputs the data. Here is a sample code:

#include 

void saveData(char* str1, char* str2) {
    // 将数据存储到变量中
    char* data = strcat(str1, str2);

    // 将存储的数据传递到输出数据的模块中
    outputData(data);
}

void outputData(char* data) {
    printf("Stored data: %s\n", data);
}

int main() {
    char* str1 = "Hello, ";
    char* str2 = "world!";

    // 调用存储数据的模块
    saveData(str1, str2);

    return 0;
}

In this example, the saveData function takes two parameters, concatenates them into a string and stores them in a variable, which is then passed to the outputData function to output the stored data. In the main function, the saveData function is called to store the data.

In your code, the lie function cannot access the variables defined in the cun function because the variables are scoped inside the function and cannot be accessed across functions. You can store data in global variables so that data can be shared between different functions. For example:

#include 

// 定义全局变量存储数据
char* storedData = "";

void cun(char* data) {
    // 将数据存储到全局变量中
    storedData = data;
}

void lie() {
    // 输出存储的数据
    printf("Stored data: %s\n", storedData);
}

int main() {
    char* data = "Hello, world!";

    // 调用存储数据的模块
    cun(data);

    // 调用输出数据的模块
    lie();

    return 0;
}

In this example, we defined a global variable, storedData, to store the data, and then stored the data into this variable in the cun function. In the lie function, we can directly access the global variable and print the stored data. From the main function, we call the cun function to store the data, and then call the lie function to output the data.

, data); } // 联系两个模块 int main () { int myData = cun ( 100 ); // 存储数据 iie (myData); // 获取存储的数据并输出 return 0 ; }

The above code can realize the connection between the module that stores the data and the module that outputs the data. First, define a myData variable in the cun() module to store incoming data and then return myData. Next, define a function in the iie() module, pass myData as an argument to the function, and perform the corresponding output operations as needed. Finally, from the main() function, call the cun() method to store the incoming data, and then pass the stored myData to the iie() method for output.
