In C/C++ programming, it is possible to split string into tokens using the built-in function strtok(...) from the header file : char* strtok(char* str, const char* delimiters); A sequence of calls to this function split str into tokens, which are sequences of contiguous characters separated by any of the characters that are part of delimiters. On a first call, the first character is used as the starting location to scan for tokens. In subsequent calls, the function expects a null pointer and uses the position right after the end of the last token as the new starting location for scanning. char str = "Test, This, Code."; char* token; token = strtok(str, ",."); { while (token!= NULL) printf("%s ", token); } token strtok(NULL, ",."); Using pipes for inter-process communication, write a C program to implement any valid three commands line pipe entered by the user. Show your program and a sample run session. Hints: The parent and children should close the unused ends of their pipes Assume that the maximum input size is 1024 characters Use the fgets(...) function for the user input Use cmd[strlen(cmd) - 1] = '\0'; to remove the ' ' from the cmd string input
