Question

I am new to C and I would like to know the difference between the below two snippet codes.When I try executing first one it works fine,but when I run the second one it gives me segmentation fault.Whats the reason for this behavior?

        printf("%c\n",*strptr++);

        printf("%c\n",*(strptr+i));

Here is the below code.

#include<stdio.h>

int main(void)
{
        char str[100]="My name is Vutukuri";
        int i=0;
        char *strptr;

        strptr=str;

        while(*strptr != '\0')
        {
                printf("%c\n",*strptr++);
                //printf("%c\n",*(strptr+i));
                //i++;
        }
        return 0;
}

Entirely different.

The first snippet prints the character at strptr and then increments strptr by one.

The second snippet prints the character at strptr + i.
