Thread: Very stupid question about pointers

Hi, i just want to make sure, Is this correct?

Code:

int f1(char *a)
{
      return f2(&a);
}

int f2(char *a)
{
       *a++;
       return 1:
}

or should be;

int f1(char *a)
{
      return f2(*a);
}

Thank you!!

Hmmm .. thats true.. so i would just have to make like this?Yea thats makes sense...

Code:

int f1(char *a)
{
      return f2(a);
}

I tryed to make that like here:

Code:

#include <stdlib.h>
#include <stdio.h>

int f2(char *a);
int f1(char *a);


int main()
{
    char a;
    int b;
        
    a = 100;
    
    b = f1(&a);
       
   printf("%u \n", a);

    
    system("PAUSE"); 
}

int f1(char *a)
{
      return f2(a);
}

int f2(char *a)
{
       *a++;
       return 1;
}

But the output is 100.. whats wrong?

i did try with a++ but with the same output...

Thank you!
