Q1: Draw a process tree (as in Figure 1) to illustrate parent-child relationship for the C code given in program 2. For each node on the tree, write the following information: i The process identifier (assumed that the parent process identifier is assigned with an integer 21). The return value of the fork() statement Generated output 111. #include #include main() { int pidl, pid2, pid3; pidl=fork(); if (pidl == 0) else { printf("\n I love \n"); printf("\n Operating system\n"); pid2-fork(); if (pid2 == 0) else { } printf("\n difficult \n"); pid3=fark.): printf("\n but interesting!!\n"); RE"\n class, \n"); Program 2: Generation of child process
