Is there assurance of salvation in Catholicism?

Among some Protestant groups such as Evangelicals and Pentecostals, it is a very common question to ask "*Are you saved?*" or *"Are you born again?*". They say that the moment you believe in Jesus Christ, confess your sins, ask for forgiveness and have the peace of forgiveness, you are saved. The evidence of Salvation is then found in the life of the person through repentance, change in character, desire for God and His word, desire to share the gospel, etc. Do Catholics also have Assurance of Salvation? At what point in their life can they say that they are saved and will go to Heaven? Or, do they strive their whole life in order to have Salvation?
