叩谢大神！！！

非常棒的项目，能够快速分析代码结构！ 😄

求大神支持trycatch和lambda

目前不支持函数递归调用，希望能够完善增强一下，谢谢！

#include <bits/stdc++.h>
using namespace std;

int f(int n) {
if (n <= 2) return n;
return f(n - 1) + f(n - 2);
}

int main() {
int n, ans = 0;
cin >> n;
ans = f(n);
cout << ans << endl;
return 0;
}

比如流程图里只包含if else这些分支选项

您好，
命令行处理下面的代码报错“unexpected dumy ast node”，但是用图形界面gui软件就可以识别if-else语句，麻烦大神修复一下命令行的问题，谢谢！

`#include
using namespace std;

int main(){
int a = 10, b = 5;
if(a > b) {
cout << "ok";
} else {
cout << "bad";
}
return 0;
}`

请问作者后续会打算添加支持java吗》或者提供一下相关思路

打开exe闪退

The following code,

#include <stdio.h>

static void a(void)
{
	printf("a\n");
}

static void b(void)
{
	printf("b\n");
}

static void x(int y)
{
	if (y > 0) {
		return a();
	} else {
		return b();
	}
}

int main(void)
{
	int y;
	scanf("%d", &y);

	x(y);
}

With the following parameters,

cxx2flow test.c x | dot -Tpng -o test.png

Results in this output,

直接在CMD中执行程序报 0xc000007b 错误，查阅错误码得知是执行文件格式错误。
于是试着在Mingw里面执行...打开了...
应该不算预期打包的行为

这样各个平台都方便使用。再就是mac版的gui有问题，测试电脑m1 pro
