int main(void) Any suggestions?
Just placed return 0 in your main(). Your function main returns an int (int main(void)) as such you should include a return in the end of it.
You are watching: Warning: control reaches end of non-void function
Control reaches the finish of a non-void function
Problem: I received the following warning:warning: control reaches end of non-void function
Solution: This warning is comparable to the warning defined in Return with no value. If manage reaches the end of a duty and no return is encountered, GCC assumes a return with no return value. However, because that this, the duty requires a return value. At the finish of the function, add a return statement that returns a an ideal return value, even if regulate never reaches there.

Solution:
int main(void) my_strcpy(strB, strA); puts(strB); return 0;

As an alternative to the noticeable solution of including a return statement come main(), you have the right to use a C99 compiler (“gcc -std=c99” if you are using GCC).
In C99 it is legal because that main() no to have actually a return statement, and then the final } implicitly returns 0.
$ gcc -c -Wall t.ct.c: In role ‘main’:t.c:20: warning: control reaches end of non-void function$ gcc -c -Wall -std=c99 t.c$ A note that purists would think about important: you need to not solve the warning by proclaiming main() as returning type void.

The main duty has a return-type the int, as indicated in
int main(void)however her main function does not return anything, it closes after
puts(strB);Add
return 0;after that and it will certainly work.
