How many keywords in cpp

We cannot use them as variables in programming. In this section, we are going to discuss some of them with the help of some examples. If: This keyword is used to check the condition. If the condition becomes true, it executes the statement following if. If the condition becomes false, the statement following the else will be executed. Based on the cases, it executes the statement. In the first output, the entered number is among the cases, so it executes the statement flowing the match cases.

In the second output, we can see that, the entered number does not match the cases, hence it executes the statement follows the default keyword. First, it checks the condition, if condition matches, statements the following while will be executed. Working of do is the same, the only difference does first execute the statement and then check the condition, on the other hand, the whole first check condition then executes the statements.

It is a loop control statement that executes the loop until the given condition matches. Based on the condition, it breaks the loop. A keyword break can also be used with a switch statement to break the loop. It is exactly the opposite of the break statement.

Continue Statement will continue the execution of the loop, it only skips the line where it is mentioned. In the program given below, we create two labels even and odd to transfer the flow of control.

A variable that is declared as const remains constant. The value of the constant variable cannot be changed. In the first program, you can see that the value of i has been changed. In the second program when we are going to change the value of constant, be it throws the error. It declares the all the variables in one group be following the struct keyword. After that creating an object of the struct, all the variables are retrieved. From cppreference. Keywords Escape sequences.
