C++ : Segitiga Pascal

next, segitiga pascal. dengan input tinggi segitiga yang di inginkan

#include
main()
{
int a,b,c,d,e,in;
int A[100]={0,1};
int B[100];
int C[100];      

printf("Masukkan tingi segitiga:");
scanf("%d",&in);

a=0;
b=1;
d=in;
e=d;


while(b<=in)
{
while(d>=1)
{
printf("  ");
d--;
}

c=0;   
while(c<=a)
{
B[c]=A[c]+A[c+1];
//printf("B[%d]=A[%d]%d+A[%d+1]%d=%d  ",i,i,A[i],i,A[i+1],B[i]);
C[c+1]=B[c];
printf("%d   ",B[c]);
c++;
}

C[0]=0;
C[a+2]=0;




c=0;
while(c<=a+2)
{
A[c]=C[c];
//printf("%d-",A[i]);
c++;

}

a++;
b++;

d=e;           
d--;
e=d;                  

//printf("a=%d,b=%d,in=%d,i=%d",a,b,in,i);
printf("\n");
}
}

dipahami dulu baru nanya ya, :D next assignment : Sorting Number
