What is difference between if and if-else statement in C++?

Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.

What is the difference between simple if and if-else?

These are known as conditional statements that judge a statement on Boolean outputs of true or false. In case the “if” condition is false, then the “else if” condition is evaluated in a sequential manner till a match is found. In case all conditions fail, then the action defined in the “else” clause is executed.

What is the if statement in C++?

The C++ if statement evaluates whether an expression is true or false. If the expression evaluates to true, the program executes the code in the conditional statement; otherwise, the program does not execute the code in the conditional statement.

What is the difference between if and nested IF?

The block of code following the else statement is executed as the condition present in the if statement is false. A nested if in C is an if statement that is the target of another if statement. Nested if statements mean an if statement inside another if statement.

What is the difference between if and if?

In both cases you have a conditional sentence. What if means What will/would happen if… You are right when you say it is used in a question. If on the other hand is used to introduce a conditional clause, not necessarily a question.

What is the difference between if if and if else if?

if vs if else The if statement is a decision-making structure that consists of an expression followed by one or more statements. The if else is a decision-making structure in which the if statement can be followed by an optional else statement that executes when the expression is false.

What is difference between if else if and else?

The difference between else and else if is that else doesn’t need a condition as it is the default for everything where as else if is still an if so it needs a condition.

What is the difference between an if statement in if else statement and an IF ELSE IF statement?

The if statement is a decision-making structure that consists of an expression followed by one or more statements. The if else is a decision-making structure in which the if statement can be followed by an optional else statement that executes when the expression is false.

What is difference between if else and ELSE IF?

Conditional Statements Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.

What is an IF AND THEN statement?

A conditional statement (also called an If-Then Statement) is a statement with a hypothesis followed by a conclusion. The hypothesis is the first, or “if,” part of a conditional statement. The conclusion is the second, or “then,” part of a conditional statement. The conclusion is the result of a hypothesis.
