It’s interesting.
This program reads environmental variables. It is as same as
"env" command in unix.
But program is not proper. i.e. if you pass n arguments to
program, then it reads n environmental variables only.
Try this program
void main(int argc,char *argv[],char *env[])
{
int i;
if (2 <=argc){
for(i=0;i<atoi(argv[1]);i++)
printf("\n%s",env[i]);
}else printf("\nPlease enter no. of env variables you want
e.g. 'a.out 5'\n");
}

#include #include struct stu { int i; char j; }; union uni { int i; char j; }; void main() { int j,k; clrscr(); struct stu s; j=sizeof(s); printf("%d",j); union uni u; k=sizeof(u); printf("%d",k); getch(); } what is value of j and k.

Write a C/C++ program that connects to a MySQL server and checks if the InnoDB plug-in is installed on it. If so, your program should print the maximum number of concurrent threads that the InnoDB plug-in can create.
