Rounding off a value means replacing it by a nearest value that is approximately equal or smaller or greater to the given number.

y = (int)(x + 0.5); here x is any float value. To roundoff, we have to typecast the value of x by using (int)

Example:

#include

int main ()

{

  float x = 2.6;

  int y = (int)(x + 0.5);

  printf ("Result = %d\n", y );

  return 0;

}

Result : 3

SNOBOL is a high-level computer programming language used especially in manipulating textual data. It is mainly used for string operations and was developed between 1962 and 1967.

This is a common error while compiling C program in Linux. This error occurs when you are using pthread_create function to create threads in your programs.

To fix this problem ensure following points:
Include header file pthread.h in your program.
Add –lpthread linker flag with compilation command.
1- Include Header file
#include <stdio.h>
#include <pthread.h>
...
...
2- Compile command
gcc main.c -o main -lpthread

While extracting a float argument using va_arg we should have useed 

c = va_arg (ptr, double)

An explicit intent explicitly defines the activity the developer wishes to start. 

Script code :

Intent myIntent = new Intent(this, MyNewActivity.class);

startActivity(myIntent);

int a = 1, b , dummy;

a > 10 ? b = 20 : dummy =1;

Note that the following would not have worked:

a > 10 ? b = 20 : ;;
