If the values are not equal, then the condition becomes true.Ĭhecks if the value of left operand is greater than the value of right operand.

If yes, then the condition becomes true.Ĭhecks if the values of two operands are equal or not.

We shall learn more about with relational operators and their usage in one of the following chapters.Ĭhecks if the values of two operands are equal or not. Relational operators are also binary operators, needing two numeric operands. The most common relational operators are less than (), less than or equal to (=), equal to (=), and not equal to (!=). These operators are used to compare two operands and return a boolean value (true or false). We are also acquainted with relational operators while learning secondary mathematics. Increment operator increases the integer value by one.ĭecrement operator decreases the integer value by one. Modulus Operator and remainder of after an integer division. Assume variable A holds 10 and variable B holds 20 then − The following table shows all the arithmetic operators supported by the C language. We shall learn more about arithmetic operators in C in a subsequent chapter. These operators are binary in nature in the sense they need two operands, and they operate on numeric operands, which may be numeric literals, variables or expressions.įor example, take a look at this simple expression − Arithmetic operators are used in forming an arithmetic expression. In addition, the modulo (%) is an important arithmetic operator that computes the remainder of a division operation. The most common arithmetic operators are addition (+), subtraction (-), multiplication (*), and division (/). These operators are used to perform arithmetic operations on operands. We are most familiar with the arithmetic operators. Thereafter, we have provided independent chapters on each of these operators that contain plenty of examples to show how these operators work in C Programming. Here, you will get an overview of all these chapters. We will, in this chapter, look into the way each operator works. Unary operators − ++ (increment), - (decrement), ! (NOT), ~ (compliment), & (address of), * (dereference)īinary operators − arithmetic, logical and relational operators except !Ĭ language is rich in built-in operators and provides the following types of operators − They need one, two or three operands respectively. An operator needs one or more operands for the operation to be performed.ĭepending on how many operands are required to perform the operation, operands are called as unary, binary or ternary operators. By definition, an operator performs a certain operation on operands. NewString = newString + chars.charAt(foundAt) window.An operator is a symbol that tells the compiler to perform specific mathematical or logical functions. newString = newString + chars.charAt(foundAt) Įlse if((chars.indexOf(data.charAt(i)) < 0))įoundAt = ((chars.indexOf(data.charAt(0 + i)) + delta)) % chars.length window.alert(foundAt) function getChars(data,delta)įoundAt = (chars.indexOf(data.charAt(i)) + delta) window.alert(foundAt) I've been working on this last part for like 2 hours now. This is an assignment for class so if possible please keep it to just modulus. I want to be able to give my function ('A', -1) or any negative number and have it return 'Z'. A problem arises however if the chars.charAt(chars.getIndexOf(data.charAt(i))) ever equals a number less than 0. SO if given getchars('H',-2), the function is supposed to return F. delta is the number of letters you have to move forward or backwards to get the real letter. I'm trying to loop through the alphabet using modulus. I've been stuck on this last part of my assignment for the longest time.
