Problem in Code

[MAhmed]

i'm making a code in which user will give input and it will return multiplication
for example if user give input "6" it should return "720" because 6*5*4*3*2*1 = 720
please correct the below code
hope you understand if not then comment

#include<stdio.h>
#include<conio.h>

int main()
{
clrscr();
int a=0;
int d=0;
printf("Enter any Number"); scanf("%d",a);

for(int b=1;b<=a;b++)
  {
   for(int c=2;c<a;c++)
    {
    d=a*c;
    }
   }
   printf("%d",d);
   getch();
   }

Hi,
Try this :

#include<stdio.h>
#include<conio.h>
int main()
{
clrscr();
int a, b, c = 0;
printf("Enter any Number");
scanf("%d", &a);
b = a;
for(int i = a; i >= 1; i--)
  {
     if(!c) c = b; else c *= b;
     b--;
  }
   printf("%d", c);
   getch();
   }
