给出一下程序执行结果

#include <iostream.h>

int fun(int);

void main()

{ int a(3);

static int b;

b+=fun(a);

cout<<"a="<<a<<",b="<<b<<endl;

b+=fun(a);

cout<<"a="<<a<<",b="<<b<<endl;

}

static int a=10;

int fun(int x)

{ static int b(5);

b+=a;

cout<<"a="<<a<<",b="<<b<<endl;

return b;

}

#include <iostream>
using namespace std;

int fun(int);

int main()

{ int a(3);

static int b;

b+=fun(a);

cout<<"a="<<a<<",b="<<b<<endl;

b+=fun(a);

cout<<"a="<<a<<",b="<<b<<endl;

getchar();

}

static int a=10;

int fun(int x)

{ static int b(5);

b+=a;

cout<<"a="<<a<<",b="<<b<<endl;

return b;

}

运行结果;

a=10,b=15 a=3,b=15 a=10,b=25 a=3,b=40 Press any key to continue
