运行程序只出现press any key to continue

Question

#include
void DrawPic(int n,char c)
{
int i,j;
for(i=1;i<=n;i++)
{
for(j=1;j<=n-1;j++)
{
printf(" ");
}
for(j=1;j<=2*i-1;j++)
{
printf("%c",c);
}
}

 return ;

}
int main()
{
int a=7;
char b='*';
void DrawPic(a,b);
return 0;
}

Answer 1

main函数中写错了，应该这样写：
int main()
{
int a=7;
char b='*';
DrawPic(a,b);
return 0;
}
