//Pascal triangle in this example contains

int factorial(int);
int C(int,int);
void space(int);
void writer(int,int);

int main()
{
int last,sender;
do{
printf("Enter a number from 0 or larger");
scanf ("%d",&last);
}while(last<0);

for(sender=0;last>=sender;sender++)
writer(sender,last);

getch();
return 0;
}

//****space printer****
void  space(int space)
{
int counter;
for(counter=0;space>=counter;counter++)
{
printf("  ");
}
}

//*******factorial*****
int factorial(int incoming)
{
int counter,result=1;
for(counter=1;incoming>=counter;counter++)
{
result*=counter;
}
return result;
}

//***combination calculate***
int combinasyon(int n,int r)
{
int result;
result=factorial(n)/(factorial(r)*factorial(n-r));
return result;
}

//*********printer***********
void writer(int incoming,int last)
{
int counter;
space(last-incoming);
for(counter=incoming;counter>=0;counter--)
printf("%4d",combinasyon(incoming,counter));
printf("\n");
}``````

can anybody help??
