Why * is used in C?

it replaces that line with all the text inside 'stdio. h'. it replaces all instances of ADD with definition of ADD. So # is used by C compiler to know which lines need preprocessing.

How do you call a function in C?

  • #include<stdio.h>
  • // function prototype, also called function declaration.
  • void swap(int a, int b);
  • int main()
  • {

  • // calling swap function by value.
  • printf(" values before swap m = %d and n = %d", m, n);
  • Is there else if in C?

    Else If Statement in C. The Else If Statement in C is instrumental while we have to test several conditions. If the condition result is TRUE, then the statements present in that block will run. If the result is FALSE, Javac verifies the Next one (Else If condition) and so on.
