see this c code.
#include<stdio.h>
void fn (int *ptr)
{
const int val=100;
ptr=&val;
}
void fn1(int *ptr)
{
*ptr = 100;
}
main()
{
int i=10;
printf("%d ", i);
fn(&i);
printf("%d ", i);
fn1(&i);
printf("%d ", i);
}
What is the difference between fn and fn1?
I expected the output to be 10 100 100
but it came as 10 10 100.
can anyone explain what happens in fn.
why 100 in fn is not stored in ptr.
