C Tutorials for Beginners

The preference in which arithematic operations are performed in an arithematic expression is called as Hierarchy of operations. Its very important in C Programming to predefine the Hierarchy of operations to the C compiler in order to solve the given arithematic expression correctly. e.g.: If a programmer wishes to perform ,z=a+b/c;it may be interpretted as z=(a+b)/c or z=a+(b/c). and if a=3,b=6,c=2 then using the same expression we will obtain two different answwers as z=4.5 or z=6. To avoid this condition we must be aware of hierarchy of operations used in C programming. In arithematic expressions scanning is always done from left to right. The priority of operations is as shown below, Priority Operators First Paranthesis os brackets() Second Multiplication & Divison Third Addition & Substraction Fourth Assignment i.e.= If we consider the logical operators used in C language,the operator precedence will be like; Operators Type !
