Pointers and Addresses in C
- by Mohit
#include "stdio.h"
main()
{
int i=3,*x;
float j=1.5,*y;
char k='c',*z;
x=&i;
y=&j;
z=&k;
printf("\nAddress of x= %u",x);
printf("\nAddress of y= %u",y);
printf("\nAddress of z= %u",z);
x++;
y++;y++;y++;y++;
z++;
printf("\nNew Address of x= %u",x);
printf("\nNew Address of y= %u",y);
printf("\nNew Address of z= %u",z);
printf("\nNew Value of i= %d",i);
printf("\nNew Value of j= %f",j);
printf("\nNew Value of k= %c\n",k);
}
Output:
Address of x= 3219901868
Address of y= 3219901860
Address of z= 3219901875
New Address of x= 3219901872
New Address of y= 3219901876
New Address of z= 3219901876
New Value of i= 3
New Value of j= 1.500000
New Value of k= c
The new address of variable y and z are same. How can two variables have same address and et have different values?
Note: I used gcc compiler on Ubuntu 9.04
