What should be the output?

Question

I'm expecting h here.But it is showing g. Why?

char *c="geek"; 
printf("%c",++*c);

Answer 1

You are attempting to modify a string literal, which is undefined behaviour. This means that nothing definite can be said about what your program will print out, or indeed whether it will print anything out.

Try:

char c[]="geek"; 
printf("%c",++*c);
