7. Python Vs C/C++ 모두 같은 생각의 소스 ¶
- 같은 생각으로 작성한다면 소스가 어떻게 표현될까 궁금했다. 소스양만 따지면, Python 을 위한 문제인가.
- 포멧팅 이용, index 두개
7.1. Python ¶
Guido van Rossum 이라면 이거에 찬성할것 같다.
~cpp
num = input("plz input number of asterisk: ")
format = ( '%%%ds '% (num) ) * 4
for odd,even in zip(range(1,num+1), range(num,0,-1)):
print format%( ('*'* odd,'*'*even) * 2 )
7.2. C ¶
Kernighan과 Ritchie가 이걸 찬성할까? 모르겠다.
~cpp
#include <stdio.h>
#define MAX 21
int main(){
char odd[MAX],even[MAX],format[20];
int i,j, num;
printf("plz input asterisk number(below %d):",MAX);
scanf("%d",&num);
if( num > MAX ) exit(0);
sprintf(format,"%%%ds %%%ds %%%ds %%%ds\n",num,num,num,num);
memset(odd,0,MAX);
for(i=1,j=num;i<=num;i++,j--){
memset(odd, '*', i);
memset(even,'*', j);
even[j]=0;
printf(format,odd,even,odd,even);
}
return 0;
}
7.3. C++ ¶
Bjarne Stroustrup ,Alexander Stepanov는 어떻게 작성하길 원할까?
~cpp
#include <iostream>
#include <string>
using namespace std;
inline void print(int& num,string& str){
cout.width(num+1);
cout<<str;
}
int main(){
int num;
cout << "plz number of asterisk:";
cin >> num;
string asterisks;
asterisks.assign(num, '*');
for (int i=1, j=num;i<=num;i++,j--){
string odd = asterisks.substr(0,i);
string even = asterisks.substr(0,j);
print(num,odd);
print(num,even);
print(num,odd);
print(num,even);
cout << endl;
}
return 0;
}
이게 조금더 C++ 다운걸까?~cpp
#include <iostream>
#include <string>
using namespace std;
int main(){
int num;
cout << "plz number of asterisk:";
cin >> num;
string odd, odd_s, even, even_s;
string oddf,evenf;
for (int i=1, j=num;i<=num;i++,j--){
oddf = odd.assign(i,'*') + odd_s.assign(j,' ');
evenf = even.assign(j,'*')+ even_s.assign(i,' ');
cout << oddf << evenf << endl;
}
return 0;
}
