Memory allocated for any structure is equal to the sum of
memory required by each structure member.

Example: In a structure 'abc' below, memory allocated will
be 7 Bytes (2 Bytes for int a + 1 Byte for char b + 4 Bytes
for float c ina 32 bit processor)
struct abc
{
int a;
char b;
float c;
}

But in union memory allocated for it is equal to the memory
required by the biggest (in terms of memory it use) union
member.

Example: In a union 'abc' below, memory allocated will be 4
Bytes as float c is the biggest union member here and it
uses 4 Bytes of memory in 32 bit processor.

union abc
{
int a;
char b;
float c;
}

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 ?????? */ }
