Major operations are three operations: Compiling and processing data done by CPU Graphic Generation and processing done by GPU Arithematic and logic Processing Done by ALU
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 beinterpretedas 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 differentanswersas 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,PriorityOperatorsFirstParenthesisos brackets()SecondMultiplication & DivisionThirdAddition & SubtractionFourthAssignment i.e.=If we consider the logical operators used in C language,the operator precedence will be like;OperatorsType!Logical NOT* / %Arithmetic and moulus+ -AritmeticRelational== !=Relational&&Logical ANDLogical OR=AssignmentIn the tables above,the higher the position of an operator,higher is its priority.
It means to Simplify
to perform arthmatic and logical operations
We can not perform Shell Scripting in DOS, we can do Batch programing in DOS..
#include<iostream.h> //using name spacestdlib ///////////////////////////////// display a program contains both arithematic and statistical operations in loop int main() { int opt; float stat; cout<<"enter the four basic operation"<<endl; cout<<"displaying the optional by using basic operation and statistical operation"<<endl; cin>>arith opt>>stat;

The processor can perform approximately 2.5 billion floating point operations per second.
Because if you perform the operations in a different order your answer will be wrong.
