Statement 1 sets a variable before the loop starts:int i = 0 Statement 2 defines the condition for the loop to run:i < 5. If the condition is true, the loop will start over again, if it is false, the loop will
Inside the main() function, we declare four variables: n to store the number of terms in the Fibonacci series, t1 initialized to 0 (the first term of the series), t2 initialized to 1 (the second term), and t3 to hold the next term in the series. Next, we use cout statement to ...
StatementList 2 2 is omitted in a forever loop, we is omitted in a forever loop, we get a get a test-at-the-bottom test-at-the-bottom or or post-test post-test loop: loop: for (;;) { StatementList 1 if (Expression) break; ...
While Loop with break Statement You can break the while loop abruptly usingbreakstatement.breakstatement ends the execution of the wrapping loop. In the following example, we shall write a while loop that prints numbers from1to10. But, then we include a break statement such that wheniis4, we...
In the above code snippet, we declare and initialize a variable i with the value of 1. We then make use of a while loop to print some statements. A test expression (i<5) is checked, and the control moves to the first statement. We use the cout statement inside the while loop to ...
Like a ‘while’ statement, except that it tests the condition at the end of the loop body. nested loops You can use one or more loop inside any another ‘while’, ‘for’ or ‘do..while’ loop. https://www.tutorialspoint.com/cplusplus/cpp_loop_types.htm...
The expression statement used as loop-statement establishes its own block scope, distinct from the scope of init-clause, unlike in C++: for (int i = 0; ; ) { long i = 1; // valid C, invalid C++ // ... }It is possible to enter the body of a loop using goto. When entering ...
except that names declared in the for-init-statement are in the same declarative-region as those declared in the condition [...] 这意味着for-init-statement和statement的作用域相同*,下面的代码会导致错误 for(int i = 0; i < 5; i++){ int i = 10; // Invalid. // ... } 在C语言...
