Can you fix my code?

#include #include #include

int main(int argc, char *argv[]) { pid_t pid, pid1; int n;

if (argc == 1) { fprintf(stderr,"Usage: %s ", argv[0]);

return -1; }

n = atoi(argv[1]);

/* add your code below, following the code structure of Figure 3.34 (page 152) */ pid = fork(); if (pid

while (n != 1) {

scanf("%d",&n); printf("%d, ", n); if (n % 2 > 0) n = 3 * n + 1; else n = n / 2; } printf("1 ");

return 0; }

For example, if n=35, the sequence is 35,106,53,160,80,40,20,10,5,16,8,4,2,1 Write a C program using the fork () system call that generates this sequence in the child process. The starting number will be provided from the command line. For example, if 8 is passed as a parameter on the command line, the child process will output 8,4,2,1. Because the parent and child processes have their own copies of the data, it will be necessary for the child to output the sequence. Have the parent invoke the wait () call to wait for the child process to complete before exiting the program. Perform necessary error checking to ensure that a positive integer is passed on the command line
