Mathematical Statements and assignments 

  Within C we can directly load up the variable from within the program using the mathematical expression equates (=) e.g.

  a= 'h';     Stores the character h in the variable A
 
  a=1;      Stores the number 1 in the variable A
 
  b= 1.00E-10;    Stores the number 1x10-10 in B
 
  c = 2.345;    Stores the number 2.345 into c
 
The assignment could be a self replacement type i.e.
 
    A=A+n;  
 
Adds n to the contents of the variable A and replaces the old value in A with the new one .The + operator is a mathematical operator which means add , likewise.

     * means multiply
    / means divide
    - means subtract
    % (remainder of an integer division)
  
ANSI C allows us to replace the simple formula A = A + n by a condensed version i.e
 
    A+=n;   means A = A +n; e.g. a+=3.2 or a+=2;  
    A-=n;    means A = A-n;
 
Likewise *=, /=, %= also exists. If the element to be subtracted/added is always one then we can use the increment operator (++) and decrement operator (--) i.e. ++A, A--, these can be pre operators and post operators (see loops) i.e. A+=1. Also parentheses (brackets) are used i.e. (). To supplement the C mathematical expressions scientific functions are available. We shall discuss these under the section concerned with functions. We can now construct simple programs using scanf, printf and mathematical functions.
