Use of git commands

Aim:

1)To compile gcc version 4.5.0,
2)To detect simple 'if-else' statements after reading source code of gcc.

3)Generate exception to handle 'if'.
4)Use git commands to point out difference made in newer compiled gcc from existing gcc on system.

3)Use of git commands using test.c file

[swati@localhost ~]$ cd repo


[swati@localhost repo]$ cp /home/swati/test.c /home/swati/repo/
