Question

I am just learning some pointers stuff in C and I happened to learn that using the * one can dereference the pointer. So I wrote the following code to check for that.

#include<stdio.h>
#include<string.h>

char *findChar(char *s, char c){
  while(*s!=c){
     s++;
  }
  return s;
}

int main(){
  char myChar='a';
  const char myString[]="Hello abhishek";
  char *location;
  location = findChar(myString,myChar);
  puts(location);
  char temp = *location;
  printf(temp);
}

I assume that temp should get the value pointed by the character pointer location, But this program is giving me a segmentation fault. Please clearify what I am doing wrong?

Answer 1

The following is incorrect:

 char temp = *location;
 printf(temp);

If you want to print out the char, use the following:

 char temp = *location;
 printf("%c\n", temp);

The first argument to printf() should be the format string.
