deprecated conversion from string constant to ‘char*’

How to get rid of compiler error-

deprecated conversion from string constant to ‘char*’

I got this compilation error while compiling the below code.

void ABC(char *strng) {};
ABC("Hello World");
or
void ABC(char *strng){};               //This code may compile but the window will crash on execution
char *strng1="Hellow World";
ABC(strng1);

I find two solution for this...
1.
void ABC(char *strng){};
char strng1[] ="Hellow World";
ABC(strng1);

2. define const every where if the sting does no changes.
void ABC(const char *strng){};
const char *strng1 ="Hellow World";
ABC(strng1);
