c program absolute value number

For beginners
{I am going write the c program but before you need a c compiler(software).there are a lot of compilers(software) for windows 7  like Code::Blocks,dev c++ . Download dev c++ its free and install it in your computer.open  dev c++ go to file-->new-->source file.} 

#include<stdio.h>

#include<conio.h>

int main (void)

{

int num;

printf ("enter your number: ");

scanf ("%i", &num);

if(num < 0)

num = -num;

printf ("The absolute value is %i\n", num);

getch();

return 0;

}

Output
enter your number: -100
The absolute value is 100

For beginners
