You need not write #include, but at the time of compilation you need to compile with options which direct compiler to include files in the provided directory. in gcc it is done by -I option.

Let's understand this by going through the following code
#include<stdio.h>
int f1();
int f2();
void main()
{
printf("%dt%d",f1(),f2());
}int f1()
{
printf("f1() enteredn");
return 4;
}
int f2()
{
printf("f2() enteredn");
return 5;
}
O/P-
f2() entered
f1() entered
4 5
we can conclude f2() is 1st executed
then f1() and in the end printf().hence we can say the precedence of execution of functions are from right to left.geek Jack

The correct answer is actually a little bit of 2 and a little bit of 3.For example, an int has a _required_ minimum range of -32767 to 32767; this means it has to be at least 16 bits wide, even if the...
