问题描述
我无法将数组作为参数传递给具有默认值的 int main()
。
例如:
int main(int a){}
奇妙。
int main(int a = 1){}
传递 int main()
数组也非常奇妙:
int main(int a [3])
但是,合并这两个概念似乎是:
int main(int a [1] {0,1})
在大量的,我没有找到解决方案。 >
请帮助我这是你唯一的希望!
EDIT
简而言之,目的是为了使我的代码尽可能少的线路,对于我的教授最近发布的挑战(不是为了学习)。该任务是创建递归的12天的圣诞节计划
这是我当前的计划
#include< iostream>
#include< string>
void p(std :: string v){std :: cout< std :: string v [13] = {梨树中的鹧鸪\\ n,2 Turtle Doves \\\
,3 French Hens \\\
,4 Colly Birds \\\
,5 Gold Rings\\\
,6 Geese-a-Laying\\\
,7,9,9,9,9等。 Piping \\\
,12 Drummers Drumming \\\
,};
int main(){
switch(v [12] .length()){
case 12:system(pause); return 0;
case 11:p(v [11]);
case 10:p(v [10]);
case 9:p(v [9]);
case 8:p(v [8]);
case 7:p(v [7]);
case 6:p(v [6]);
case 5:p(v [5]);
case 4:p(v [4]);
case 3:p(v [3]);
case 2:p(v [2]);
case 1:p(v [1]);
case 0:p(v [0]);
} v [12] + =0;
main();
}
我想将数组的经文作为参数传递给main在函数上面声明它。我知道,不是最内存/堆栈意识。但它会消除一行:)
此最好地解释:
这就是为什么你可以声明一个函数
void foo(int bar []);
但您不能声明
void foo(int bar [] = {0,1});
与 main()无关
。
I am having difficulty passing an array as an argument into int main()
with default values.For example:
int main(int a){}
works wonderfully. As does
int main(int a = 1){}
Passing int main()
an array also works wonderfully:
int main(int a[3])
However, combining these two concepts seems break:
int main(int a[1] = {0,1})
After a significant amount of googleing, I haven't found a solution.
please help me SO, you're my only hope!
EDIT
The purpose of this, in short, is to make my code as little lines as possible, for a challenge my professor recently issued (not for points -- just for learning). The assignment is to create a recursive "12-days-of-chirstmas" program
This is my current program
#include <iostream>
#include <string>
void p(std::string v){std::cout<<v;}
std::string v[13] = {"A Partridge in a Pear Tree.\n\n","2 Turtle Doves\n","3 French Hens\n","4 Colly Birds\n","5 Gold Rings\n","6 Geese-a-Laying\n","7 Swans-a-Swimming\n","8 Maids-a-Milking\n","9 Ladies Dancing\n","10 Lords-a-Leaping\n","11 Pipers Piping\n","12 Drummers Drumming\n",""};
int main(){
switch(v[12].length()){
case 12:system("pause"); return 0;
case 11:p(v[11]);
case 10:p(v[10]);
case 9: p(v[9]);
case 8: p(v[8]);
case 7: p(v[7]);
case 6: p(v[6]);
case 5: p(v[5]);
case 4: p(v[4]);
case 3: p(v[3]);
case 2: p(v[2]);
case 1: p(v[1]);
case 0: p(v[0]);
}v[12] += "0";
main();
}
I would like to pass in the array of verses as an argument to main instead of declaring it above the function. I know, not the most memory/stack conscious. But it would eliminate a line :)
This link explains it best:
That's why you can declare a function with
void foo (int bar[]);
but you can't declare
void foo (int bar[] = {0 ,1});
It has nothing to do with main()
.
