i design cache simulator count miss,hits,eviction.i tried compile programme next command ,it worked without error,

i pretty sure path have set while executing programme right not able find solution encounter ? help me out !!

you compiled gcc -wall hello.c -o hello.out -lm, you're looking execute ./hello.out.

if want run ./hello, compile line:

gcc -wall hello.c -o hello -lm
