I personally feel that is a good question to ask

I will look them up to find out.
Pentecostal:The Pentecostal movement within Evangelical Christianity places special emphasis on the gifts of the Holy Spirit, as shown in the Biblical account of the Day of Pentecost. Pentecostalism is similar to the Charismatic movement, but developed earlier and separated from the mainstream church. Charismatic Christians, at least in the early days of the movement, tended to remain in their respective denominations.But unlike most other Christians they believe that there is a second work of the Holy Spirit called the baptism of the Holy Spirit in which the Holy Ghost is now in them, and which opens a believer up to a closer fellowship with the Holy Ghost and empowers them for Christian service. Speaking in tongues, also known as glossolalia, is the normative proof, but not the only proof, of the baptism with the Holy Spirit. Most major Pentecostal churches also accept the corollary that those who don't speak in tongues have not received the blessing that they call "The Baptism of the Holy Spirit". This claim is uniquely Pentecostal and is one of the few consistent differences from Charismatic theology.Pentecostals believe that there are three different types of instances of speaking in tongues: One, being tongues spoken as initial evidence of the baptism of the Holy Spirit; two, being a prayer language developed in daily prayer with God; and three, being tongues and interpretation ("public utterances"). They believe that all Christians can be baptized with the Holy Spirit if they have at least repented, and genuinely ask God and wait on His timing for it to occur. Pentecostals believe that in public ordinances, someone who is given the gift of speaking in tongues may speak in tongues in a church service or other Christian gathering for everyone to hear. They believe that God will give another Christian present the gift of interpretation and that the Christian with the gift of interpretation will be able to speak what the first person did in the language of the audience so that everyone can understand what was said and be edified. They believe that only some people are given the gift of speaking in tongues while everyone has the opportunity to receive the baptism of the Holy Spirit and develop a prayer language with God. This is what Paul was spoke of in I Corinthians 12-14.
Charismatic
Charismatic is an umbrella term used to describe those Christians who believe that the manifestations of the Holy Spirit seen in the first century Christian Church, such as healing, miracles and glossolalia, are available to contemporary Christians and ought to be experienced and practiced today. The word charismatic is derived from the Greek word charis (meaning a grace or a gift) which is the term used in the Bible to describe a wide range of supernatural experiences (especially in 1 Corinthians 12-14).
Often confused with Pentecostalism (which it was inspired by), charismatic Christianity tends to differ in key aspects: most charismatics reject the preeminence given by Pentecostalism to glossolalia, reject what they consider to be legalism sometimes associated with Pentecostalism, and often stay in their existing denominations such as Roman Catholic Charismatics
Because of the continual cross-over between Pentecostalism and the modern charismatic movement, it is increasingly difficult to speak of charismatics and Pentecostals as being part of separate movements. Yet because neither movement is monolithic, it is also unfair to speak of them as being one movement either. The difference is primarily one of origins. Beliefs of the two groups are very similar; each movement, however, is unique in its historical beginnings. Having been conceived in unique contexts, the difference may secondarily be described in terms of contrasting church cultures evidenced through each movement's manners and customs (i.e., worship styles, preaching styles, altar ministry methods). Until a more acceptable broad nomenclature is used, it needs to be understood that both movements share a great deal in common, and yet can sometimes be clearly differentiated.While charismatic Christians are not exclusive to any single denomination, charismatic theology is not uniquely Protestant. There is a burgeoning charismatic movement within the Catholic Church, and Pope John Paul II was reputed to have had a charismatic priest as his personal pastor.
In the Roman Catholic church, the movement became particularly popular in the Filipino and Hispanic communities of the United States, and in the Philippines itself. Traveling priests and lay people associated with the movement often visit parishes and sing what are known as charismatic masses. It is thought to be the second largest distinct sub-movement within Roman Catholicism, along with Traditional Catholicism. It presents a difficult situation for many Church authorities, who, as always, must be careful to admit innovation only where it is clear the innovation is consistent with the Bible and the teachings of the Church.

Charismatic movement and Pentecostalism
The charismatic movement shares many similarities with Pentecostalism, and the stages of the latter seem to have been a prerequisite for the further developing of the said topic. The influence of Pentecostalism upon the charismatic movement cannot be denied. Both acknowledge the power of the Holy Spirit. Faith healing has major acceptance among adherents of both faiths, and both are known for their fiery services. Even still, many differences will allow a person to discern a charismatic from a Pentecostal, though some consider themselves both.
Pentecostals developed their own denomination, but charismatics tend to remain in their respective established churches or religious bodies. Charismatics have been susceptible to criticism that exceeds that of Pentecostalism, but criticism of both is widespread in comparison to other religious movements. Pentecostalism also developed significantly earlier than the charismatic Movement
