You cocould try using -- skip-broken to work around the problem
You cocould try running: rpm-Va -- nofiles -- nodigest

Solution: Delete the gcc, cpp, libgomp, and other Dependencies first, and then directly install gcc-c ++, so that it can automatically install the correct version of the dependent gcc, cpp, libgomp:

[Root @ localhost ~] # Yum install gcc-c ++
