Is it possible to use
strlen while declaring a new string?
char a="Hello world"; char b[strlen(a)]; // alloc memory to string b equal to the string length of a
If not, then what is the solution if I don't want to directly enter the length of another string?
And I'm unable to use the
strrev function. I get the following error
error-implicit declaration of function 'strrev' is invalid in C99
How to fix this?
