Write a C program linear.c that creates a sequence of processes with a given length. By sequence it is meant that each created process has exactly one child. Let's look at some example outputs for the program. Here the entire process sequence consists of process 18181: Sara@dell:~/OSSS$ ./linear 1 Creating process sequence of length 1. 18181 begins the sequence. An example for a sequence of length three: Sara@dell:~/OSSS$ ./linear 3 Creating process sequence of length 3. 18233 begins the sequence. 18234 is child of 18233 18235 is child of 18234 ........ this is coad .... BUt i could not compleate it .....:( #include #include #include #include int main(int argc, char *argv[]) { int N; pid_t pid; int cont; if (argc != 2) { printf("Wrong number of command-line parameters!\n"); return 1; } N = atoi(argv[1]); printf("Creating process sequence of length %d.\n",N); printf("%d begins the sequence.\n",getpid()); /* What I have to do next ?????? */ }

using only #include and #include Write a program in C that will read an input from the user and print it back to the user if it is a palindrome. The string ends when it encounters a whitespace. The input string is at most 30 characters. Assume the string has no spaces and distinguish between and lowercase. So madam is a palindrome, but MadAm is not a palindrome. Use scanf and %s to read the string. Sample Test: Enter a string: madam madam is a palindrome. Enter a string: 09023 09023 is not a palindrome.
