Give a C++ statement to Create a float pointer fptr
Answers
Answer:
Float pointer
All concepts are similar to the integer pointer. If you are directly reading this article, kindly go through the integer pointer topic before getting started with this. Data type is the only difference.
A float pointer only stores an address of a float variable.
Syntax
float *ptr;
Referencing and dereferencing of a float pointer
Example
#include<stdio.h>
int main()
{
float var = 3.1415,*ptr;
ptr = &var; //ptr references var
printf("Address of var = %x\n",&var);
printf("ptr is pointing to an address %x\n",ptr);
/* use '*' operator to access the value stored at ptr,
i.e. dereferencing ptr */
printf("Value stored at ptr = %f",*ptr);
return 0;
}
Run it
Output
For the sake of understanding better, let's assume the address of a variable var.
If we assume address of a variable var as 1024 then the output of the above program will be,
