# Code Race/2015.5.15/S'팀

스팀은 좋은겁니다
```#include<stdio.h>
int teamname();
int sum(int);

int main()
{
int k;

int j;
teamname();
scanf("%d", &k);
j = sum(k);

printf("1부터 %d의 합은 : %d\n",k, j);
return 0;

}
int teamname(void)
{
printf("    ::##==\n		::## +=\n		.**# +=\n		. + ** *= +\n		. + *+# = :\n	.*++*##         ...\n		*++*+.. : *..\n		= ******+%@::. ...: ::\n		= .  ::%****#*@%#%%#%#%%%+# + ...\n##                    *==++#***..\n		.++**:\n");
printf("팀명: S'팀\n");
printf("팀원: 서영운, 송준호, 유재범\n");
for (int i = 0; i < 40; i++)
printf("#");
printf("\n");
return 0;
}
int sum(int n)
{
int a = 0;
if (n == 0)
{
return n;
}
else
{
a += n;
a += sum(n - 1);

}
return a;
}
```

## 문제 2 ¶

```

#include <stdlib.h>
#include <time.h>
#include <stdio.h>
#pragma warning(disable:4996)

void teamname(void)
{
printf("    ::##==\n		::## +=\n		.**# +=\n		. + ** *= +\n		. + *+# = :\n	.*++*##         ...\n		*++*+.. : *..\n		= ******+%@::. ...: ::\n		= .  ::%****#*@%#%%#%#%%%+# + ...\n##                    *==++#***..\n		.++**:\n");
printf("팀명: S'팀\n팀원: 서영운, 송준호, 유재범\n");
for (int i = 0; i < 40; i++)
printf("#");
printf("\n");
}

void gugu(void){
int rand_num = 0, count=0;
srand((unsigned)time(NULL));

printf(" 숫자를 입력하세요.\n");
scanf("%d", &count);

for (int k = 0; k < count; k++){
rand_num = rand() % 9 + 1;
printf("%d\n", rand_num);
for (int i = 1; i < 10; i++){
printf("%d * %d = %d\n", i, rand_num, i*rand_num);
}
}
}
```

소스.c
```#include "header.h"

int main()
{
teamname();
gugu();
return 0;
}
```

## Extra ¶

```#include<stdio.h>
void teamname();
int sum(int);

int main()
{
int k;
teamname();
scanf("%d", &k);

printf("1부터 %d의 합은 : %d\n", k, sum(k));
return 0;
}

void teamname(void)
{
printf("    ::##==\n		::## +=\n		.**# +=\n		. + ** *= +\n		. + *+# = :\n	.*++*##         ...\n		*++*+.. : *..\n		= ******+%@::. ...: ::\n		= .  ::%****#*@%#%%#%#%%%+# + ...\n##                    *==++#***..\n		.++**:\n");
printf("팀명: S'팀\n팀원: 서영운, 송준호, 유재범\n");
for (int i = 0; i < 40; i++)
printf("#");
printf("\n");
}
int sum(int n)
{
int a = 0;
if (n == 0)
{
return n;
}
else
{
a += n+sum(n - 1);
}
return a;
}
