//A small example to show how to use execvp() function in C. We will have two .C files , EXEC.c and execDemo.c and we will replace the execDemo.c with EXEC.c by calling execvp() function in execDemo.c . //EXEC.c  #include<stdio.h>  #include<unistd.h>  int main()   {        int i;       printf("This  is EXEC.c, called by execvp() ");        printf("\n");       return 0;   }  Now,create an executable file of EXEC.c using command  gcc EXEC.c -o EXEC //execDemo.c #include<stdio.h> #include<stdlib.h>  #include<unistd.h>  int main()  {     //A null terminated array of character      //pointers       char *args[]={"./EXEC",NULL};       execvp(args[0],args);     /*All statements are ignored after execvp() call as this whole process(execDemo.c) is replaced by ...

Implement a class CppArray which is identical to a one-dimensional C++ array (i.e., the index set is a set of consecutive integers starting at 0) except for the following : 1. It performs range checking. 2.It allows one to be assigned to another array through the use of assignment operator. 3.It supports a function that returns the size of the array.
