I want to know what is difference between below two string declaration in C language

In addition to Binyamin Sharet's answer, in the first case you can change the myString pointer, but in the second case you can't. So, this code will compile and run and print "ello":

#include <stdio.h>

int main(int argc, char **argv)
{
    char *myString = "Hello\n";

    myString++;

    printf("%s", myString);
}

But this code won't compile:

#include <stdio.h>

int main(int argc, char **argv)
{
    char myString[] = "Hello\n";

    myString++;

    printf("%s", myString);
}

difference between char *myString and myString[]
