Saving the output in a text file
consider the following c program

#include<conio.h>
main()
{
int i,n;
clrscr();
printf(”Enter limit\n”);
scanf(”%d”,&n);
printf(”I will print %d times\n”,n);
for(i=0;i<n;i++)
printf(”I luv C\n”);
}
the output will be
How C Compiler decides the Garbage values in case of data overflow
Garbage value in case of data overflow
I did some intense R&D for garbage values and found these facts.After understanding these concepts u can tell what will be the garbage value to be stored in a variable in case of dataoverflow.
Here are some of the basic facts required to proceed
In case of windows(TC),

Dynamic Output in C
Dynamic output
consider the following program
#include<stdio.h>
int main()
{
long double a=3.14159265;
printf(”Value of pi=%.4Lf”,a);
return(1);
}
the output of the program will be
Value of pi=3.1416
wouldn’t it be nice if we allow the user to choose how the precession of the answer would be??
that is the output should be like this
Enter precision
6
The value of pi precised to 6 decimal number is 3.141593
Well in [...]
