hey

i have a project on logic circuit simulation.i don't know how to include basic gate images in my code,so that it is displayed with the chosen gates output.i have jgrasp c_compiler.so plz help me out.

#include<stdio.h>

int And(int a, int b);
int Or(int a, int b);
int Not(int a);
int Nand(int ,int );
int Xor(int ,int );
int Nor(int ,int );

 main()
 { 
  int ch,k,l,m,a,b,p,n,r;
    do
    {
    printf("1.And,2.Or,3.Not,4.Xor,5.Nand,6.Nor,7.Exit\n");
    scanf("%d",&ch);
    switch(ch)
   {
      case 1:printf("Enter value of a&b");
             scanf("%d %d",&a,&b);
             k=And(a,b);
             printf("%d\n",k);
             break;
      case 2:printf("Enter value of a&b");
             scanf("%d %d",&a,&b);
             l=Or(a,b);
             printf("%d\n",l);
             break;
      case 3:printf("Enter value of a&b");
             scanf("%d ",&a); 
             m=Not(a);
             printf("%d\n",m);
             break;
      case 4:printf("Enter value of a&b");
             scanf("%d %d",&a,&b);
             n=Xor(a,b);
             printf("%d\n",n);
             break;
      case 5:printf("Enter value of a&b");
             scanf("%d %d",&a,&b);
             p=Nand(a,b);
             printf("%d\n",p);
             break;

      case 6:printf("Enter value of a&b");
               scanf("%d %d",&a,&b);
                 r=Nor(a,b);
                 printf("%d\n",r);
             break;

       case 7:printf("exit");
               break;
       }        
 }
 while(ch!=7);
}

Learn about C's bit-wise (boolean) logic. Example, for Xor, in C this can be expressed as:

int Xor(int a,int b)
{
    return a^b;
}

And Not(int a) like this:

int Not(int a)
{
    return !a;
}

I leave the rest to you for exercise... :-)
