C++读取exe程序标准输出

Test.exe代码如下：逐行打印输入参数

#include <iostream>
using namespace std;

int main(int argc, char* argv[])
{
	for (int i = 1; i < argc; i++)
	{
		cout << argv[i] << endl;
	}

	return 0;
}

读取代码如下：

#include <cstdio>
#include <iostream>

int main() 
{
    FILE* pipe = _popen("Test.exe 123 abc 456", "r");
    if (!pipe) return -1;

    char buffer[128];
    while (fgets(buffer, sizeof(buffer), pipe) != nullptr) {
        std::cout << buffer; // 处理程序输出
    }

    int ret = _pclose(pipe);
    std::cout << "返回码: " << ret << std::endl;
    return 0;
}

读取结果如下：
