What is DECODE function used for? | |
DECODE is used to decode a CHAR or VARCHAR2 or NUMBER into any of several different character strings or numbers based on value. That is DECODE does a value-by-value substitution. For every value that is given in the DECODE function it makes an if then check and matches the value. The general format

printf() Function Return Value | |
What is the return value from printf() function?
printf function always returns the number of characters printed. Let us understand this with an example:
main()
{
int a=10;
printf("%d",printf("%d %d %d", a,a,a));
}
In this above program the inner printf i

How is the main() function declared? | |
The declaration of main can be done as
int main()
One more declaration that can be taken by main is command line arguments form
int main(int argc, char *argv[])
or this can also be written as
int main(argc, argv)
int argc;
char *argv[];
NOTE: It is not possible for one to declare the main

How does the function call within function get evaluated? | |
Whenever we have more than one function which is called for a finite number of times then such a function gets evaluated from inside out.
Let us understand this concept with an example.
For instance consider a function sample called within it 4 times as given in program below:
main()
{
int a=50;

What is the default return value of a function? | |
The default return value from a function is int. In other words, unless explicitly specified the default return value by compiler would be integer value from function.
When a programmer wants other than integer values to be returned from function then it is essential that the pro

What happens when a variable is not declared in function definition? | |
Generally in C program the function definition and calling takes the form as given below:
main()
{
int x,y,z;
z=sample(x,y);
printf(“%d”,z);
}
sample(x1,y1)
int x1,y1;
{
int z1;
z1= x1 - y1;
return(z1);
}
Here what happens is the values x, y gets passed to x1,y1
