sqrt function

sqrt function returns square root of a number.

Declaration :- double sqrt(double);

C programming code for sqrt
#include <stdio.h>
#include <math.h>

int main()
{
  double n, result;

  printf("Enter a number to calculate it's square root\n");
  scanf("%lf", &n);

  result = sqrt(n);

  printf("Square root of %.2lf = %.2lf\n", n, result);

  return 0;
}

Difference between asterisk and ampersand operators in c

Address Operator (& - Ampersand): Returns address of the given variable.  Consider the following example, int *ptr, var = 10; ptr = &var; ptr = &var sets the address of the variable var to pointer ptr.  & is also called as reference operator. Let us try to understand the purpose of reference operator using the following example program.   #include <stdio.h>   int main() {         int var = 10, *ptr;         /* assigning address of variable var to pointer ptr */         ptr = &var;         /* printing the address of the variable var */         printf("Address of var is 0x%x\n", &var);         /* printing the value of pointer ptr */         printf("Value of ptr is 0x%x\n", ptr);         return 0;   }   Output:   jp@jp-VirtualBox:~/$ ./a.out   Address of var is 0xbfdf202c   Value of ptr is 0xbfdf202c Indirection Operator('*' - asterisk): The dereference operator is an unary operator which returns the value of

kbhit in c

kbhit in c: kbhit function is used to determine if a key has been pressed or not. To use kbhit function in your program you should include the header file "conio.h". If a key has been pressed then it returns a non zero value otherwise returns zero. Declaration : int kbhit(); C programming code for kbhit #include <stdio.h> #include <conio.h> main() {    while (!kbhit())       printf("You haven't pressed a key.\n");    return 0; } As long as in the above program user doesn't presses a key kbhit() return zero and (!0) i.e. 1 the condition in while loop is true and "You haven't pressed a key." will be printed again and again. As a key is pressed from the keyboard the condition in while loop become false as now kbhit() will return a non-zero value and ( !(non-zero) = 0), so the control will come out of the while loop.
