Please follow the steps below and answer the questions accordingly. tinclude int Eooint nu) int rev au-0 while num > 0) revnum-rev num * 10 + num%10; u-num/10 - eEurn rev aumi Driver program to test Eoo int main0 int nu-1125; printf("Result is return %d", foo (num)); 1) Compile "q1.c" with -g option so that we can debug the executable using gdb $gcc -o ql -g ql.c 2) Lauch gdb for "q1". $gdb ql 3) List the source code of "q1.c" from line 1. (gdb)list 1 4) Set a breakpoint at the line of statement "while (num > 0)". Question: Write your command
