In all popular high-level programming languages, the order in which operators are interpreted ("operator precedence") is vital to ensuring that all compilers execute instructions in precisely the same manner, as the "order of operations" rule is vital in mathematics. In the case of C and C++, arithmetic operators are executed prior to logic operators. For a detailed description of operator precedence, see the related links below.
There are eight types of operators which are used in C language.These are- 1.Arithmetic operator 2.Assignment operator 3.Relational operator 4.Increment/Decrement operator 5.Bitwise operator 6.Logical operator 7.Conditional operator 8.Additional operator 1.Arithmetic operator:Arithmetic operators are mathmetical operator.These are addition,Subtraction,Multiplication and divison. 2.Assignment operator:Assignment operators are used to store the result of an expression to a variable.
Each operator has a certain precedence level, usually some numeric value. As you parse the expression, you compare the precedence of each operator with the precedence of the last operator, and you either generate code or you push the operator and its operand(s) on two stacks.
#include <iostream> #include <stack> using namespace std; int prec (char ch){ // Gives precedence to different operators switch (ch) { case '^': return 5; case '/': return 4; case '*': return 4; case '+': return 2; case '-': return 1; default : return 0; } } bool isOperand(char ch){ // Finds out is a character is an operand or not if ((ch>='0' && ch<='9') (ch>='a' && ch<='z')) return true; else return false; } string postFix (string infix){ string pfix = ""; stack<char> opstack; for (int i=0; i<infix.length(); i++){ // Scan character by character if (isOperand(infix[i])) { pfix += infix[i]; } else if (infix[i] ')') { // Retrace to last ( closure while (opstack.top() != '(') { pfix += opstack.top(); opstack.pop(); } // Remove the '(' found by while loop opstack.pop(); }

precedence
The order of precedence is as follows:Parenthesis (expressions within brackets)Exponents (powers)Division & multiplicationAddition & subtractionOperations with equal precedence are calculated in left-to-right order.

Though Java, unlike other languages, does not allow you to directly access the core, memory addresses and system variables, it does have binary operators, such as the shifters >>, <<, and the bitwise operators, |, &, ^. Using these operators, ALL calculations in the computer can be done, even your complicated trig functions. Though options are limited in Java, it does provide a simulated access to low level operations. The bitwise operators are in the link below. Look at the link below to see how the computer really does math.
The national government would take precedence when there is a conflict.
They are on the same level as each other. Mathematically, addition and subtraction have equal precedence and are done in a left to right order. Microsoft Excel is designed to follow the rules of mathematics, so they have equal precedence.

False. Data at the ordinal level can be either quantitative or qualitative. In ordinal data, the categories have a meaningful order or rank, but the difference between the categories is not necessarily equal.
