In Java, or C, the expression is simply:

i == j

If the two are equal, this expression will evaluate to true; if not, it will evaluate to false.

Still have questions?  ### You use the operator to reverse the meaning of a Boolean expression?

The NOT operator. E.g., NOT TRUE evaluates to FALSE while NOT FALSE evaluates to TRUE.

### What is flag controlled while loop?

A while loop evaluates a conditional expression at the start of each iteration. If the conditional expression evaluates false, execution passes to the statement that immediately follows the body of the loop. If the conditional expression evaluates true, the body of the loop executes one iteration. When the end of the loop is reached, or a continue statement is encountered within the body of the loop, control passes back to the while statement where the conditional expression is re-evaluated. If a break statement is encountered within the body of the loop, the loop terminates and control passes to the next statement. If a return statement is encountered within the body of the loop, the loop terminates and control passes to the calling function.while (expression) {// repeats until the expression evaluates false}The braces are optional when the body of the loop is a simple statement. Compound statements must be enclosed in braces.A flag-controlled while loop has a simple conditional expression that evaluates a Boolean value:bool x;// ...while (x==true) { // flag-controlled loop// ...}}The above loop can also be written without the equality operator:while (x) { // flag-controlled loop // ...}Moreover, any integral type (such as int or char) will implicitly convert to a bool such that non-zero values evaluate true and zero evaluates false. As such, any integral type can be used in a flag-controlled loop.

### What is if in C?

If is a keyword that introduces a conditional expression. If the expression evaluates true, the statement or statement block that follows is executed, otherwise control is passed to the line following the statement or statement block, which may be another conditional expression. if( expression_1 ) { // do something when expression_1 is true } else if( expression_2) { // do something when expression_1 is false but expression_2 is true } else { // do something when both expression_1 and expression_2 are false }

### What is the conditional operators in c language?

The conditional operator is also known as ternary operator. It is called ternary operator because it takes three arguments. The conditional operator evaluates an expression returning a value if that expression is true and different one if the expression is evaluated as false.Syntax:condition ? result1 : result2If the condition is true, result1 is returned else result2 is returned.

### What is a comparative operator?

Comparative operators are used to compare the logical value of one object with another and thus establish the rank (ordering) of those objects. There are six comparative operators in total: p&lt;q : evaluates true when p is less than q p&gt;q : evaluates true when p is greater than q p&lt;=q : evaluates true when p is less than or equal to q p&gt;=q : evaluates true when p is greater than or equal to q p!=q : evaluates true when p is not equal to q p==q : evaluates true when p is equal to q

Yes, any expression that evaluates non-zero is implicitly true.

### Can you Compare while and do-while?

The 'while' statement evaluates its expression at the beginning of the loop, while a 'do while' statement evaluates its expression at the end of the loop. The 'while' statement might execute no times. The 'do while' statement will execute at least one time. It depends on what you want to do, and on how you want to use the side effects, if any, of the expressions in the expression. (Before or after)

### What is a while?

The while keyword is used to create a while loop, which tests a boolean expression and executes the block of statements associated with the loop.If the expression evaluates to true, this continues until the expression evaluates to false.This keyword can also be used to create a do-while loop.Syntax:do{statements;}while(condition);

### What is it called when there is an equation that is always true?

an identity? maybe a tautology? Comment by mgately: In the field of discrete mathematics (simplified the study of logic) any expression which always evaluates to true is in fact called a tautology. While less cool sounding, an expression which always evaluates to false is just called a contradiction.

Yes.

### Is 10 equals 120 an expression or an equation?

If a statement includes an "equals" sign ( = ) then the statement is an equation. By the way . . . it may or may not be a true statement. "10 equals 120" is not true.

### What is the format of if statement in c plus plus?

Syntax:if (expression)statement;[elsestatement;]The expression must evaluate to a boolean value, where zero is false and all non-zero values are true. The statement (including the optional else statement) may be simple or compound, and may include a nested if statement. When the expression evaluates true, the first statement is invoked. If an else statement is provided, it is only executed when the expression evaluates false. After the appropriate statement is invoked, execution passes to the statement that immediately follows the entire if statement.

### What is an arithmetic IF in FORTRAN programming?

Unlike a logical IF where the control expression is Boolean and has two branches depending on whether the expression evaluates true or false, the control expression of an arithmetic IF is a numeric expression (such as x+y) and has three branches depending on whether that expression evaluates negative, zero or positive. In languages that do not provide native support for arithmetic IF (such as C++), we can implement arithmetic IF using logical IF as follows, where z holds the result of the arithmetic expression (such as z=x+y): if (z&lt;0) { // negative path } else if (z==0) { // zero path } else { // positive path }
