1st, your head file is not correct.
stolib.h -> stdlib.h
stoio.h -> stdio.h
2nd, return 0;
3rd, use this command to compile your program:
gcc test.c -o test -lm
stolib.h -> stdlib.h
stoio.h -> stdio.h
2nd, return 0;
3rd, use this command to compile your program:
gcc test.c -o test -lm

需要链接-lm库．

gcc myprog.c -o myprog -lm
