Pointer Comparison in C
Pointer Comparison in C
In C language pointers can be compared if the two pointers are pointing to the same array.
All relational operators can be used for pointer comparison, but a pointer cannot Multiplied or Divided.
Below is a program on pointer comparison for same type of pointer:
#include <stdio.h>
int main()
{
int *ptrA,*ptrB;
ptrA = (int *)1;
ptrB = (int *)2;
if(ptr2 > ptr1)
printf("PtrB is greater than ptrA");
return(0);
}
Below is a program on pointer comparison for different type of pointer:
#include <stdio.h>
int main()
{
int *ptrA;
float *ptrB;
ptrA = (int *)1000;
ptrB = (float *)2000;
if(ptrB > ptrA)
printf("PtrB is greater than ptrA");
return(0);
}
