tcp/ip is a protocol suite and is alyered architecture model that describes how data communication takes palce among communicating devices and tcp and ip are the two different protocols reside on transport layer ( layer 4) and nework layer ( layer3 ) respectively. tcp is a connection oriented protocol nd ip is a connectionless protocol.

IP is a layer 3 protocol that provides routing functionality to find the nearest path to the destination and tcp is a layer 4 protocol in tcp/ip stack and provide flow control, error control and sequencing mechanism etc. It regulate the transmission of packets inflow and outflow.

TCP/IP is arguably the single most important computer networking technology. The Internet and most home networks support TCP/IP as the "language" computers use to find and connect with each other.

The Defense Advance Research Projects Agency (DARPA) originally developed Transmission Control Protocol/Internet Protocol (TCP/IP) to interconnect various defense department computer networks. The Internet, an international Wide Area Network, uses TCP/IP to connect government and educational institutions across the world. TCP/IP is also in widespread use on commercial and private networks. The TCP/IP suite includes the following protocols.

i think TCP (Transmission Control Protocol) is a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet.

in this layer 4 protocol used for end to end reliable communication but layer 3 protocol used for routing and best selection

TCP(transmission control protocol) works on OSI 4th layer for reliable transmission & IP work on 3rd layer of OSI used for routing.

TCP is layer 4 protocol used for end to end reliable communication as well as IP is layer 3 protocol used for Routing and best path selection

Well they are the two most important protocols used in the IP model of networking.
Here TCP basically provides a kind of Reliable services means a guaranteed delivery of data to the other end by implementing the sequencing,packetization ,acknowledgment schemes.
Whereas the IP provides unreliable best effort services.It mostly deals with the packet routing and the congestion control mechanisms.It never bothers about the assured delivery of the data packet it just forwards it into the network and forgets.This forwarding will be done depending upon the destination address present in the IP Header.
Remember the flow control and the error handling will be taken care by the NAL-network access layer ie the 1st layer of the IP model.
