  2. Why would you use an assignment in a condition?

    The reason is: Performance improvement (sometimes) Less code (always) Take an example: There is a method someMethod() and in an if condition you want to check whether the return value of the method is null. If not, you are going to use the return value again. If(null != someMethod()){. String s = someMethod();

  3. Is doing an assignment inside a condition considered a code smell?

    Doing a call like GetCurrentStrings() once outside a while loop, and then calling it inside the loop, is a very common, well understood, accepted as best practice pattern. ... C++ culture is more accepting of assignment-in-condition than the other languages, and implicit boolean conversions are actually used in some idioms, e.g. type queries: ...

  4. while loop in C

    Working of while Loop. We can understand the working of the while loop by looking at the above flowchart: STEP 1: When the program first comes to the loop, the test condition will be evaluated. STEP 2A: If the test condition is false, the body of the loop will be skipped program will continue. STEP 2B: If the expression evaluates to true, the body of the loop will be executed.

  5. C

    Guess the output of this while loop. #include <stdio.h> int main() { int var=1; while (var <=2) { printf("%d ", var); } } The program is an example of infinite while loop. Since the value of the variable var is same (there is no ++ or - operator used on this variable, inside the body of loop) the condition var<=2 will be true forever and the ...

  6. C

    In C, while is one of the keywords with which we can form loops. The while loop is one of the most frequently used types of loops in C. The other looping keywords in C are for and do-while. The while loop is often called the entry verified loop, whereas the do-while loop is an exit verified loop. The for loop, on the other hand, is an automatic ...

  7. C while and do...while Loop

    The do..while loop is similar to the while loop with one important difference. The body of do...while loop is executed at least once. Only then, the test expression is evaluated. The syntax of the do...while loop is: do {. // the body of the loop.

  8. The while loop in C

    The while loop. Syntax: // body of while loop. statement 1; statement 2; Just like the if-else statement, the while loop starts with a condition. First, the condition is evaluated, if it is true then the statements in the body of the while are executed. After executing the body of the while loop, the condition is checked again, if it is still ...

  9. While Loop

    The term loop comes from the circular looping motion that occurs when using flowcharting. The basic form of the while loop is as follows: initialization of the flag. while the answer to the question is true then do. some statements or action. some statements or action. some statements or action. update the flag.

  10. Assignment Operators in C

    Simple assignment operator. Assigns values from right side operands to left side operand. C = A + B will assign the value of A + B to C. +=. Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A. -=.

  11. While loop in Programming

    While loop is a fundamental control flow structure in programming, enabling the execution of a block of code repeatedly as long as a specified condition remains true. While loop works by repeatedly executing a block of code as long as a specified condition remains true. It evaluates the condition before each iteration, executes the code block if the condition is true, and terminates when the ...

  12. Combined assignment operator in a while loop condition in C

    The test is purposely obfuscated. Here are the steps: --x > -10 always decrements x and compares the resulting value to -10, breaking from the loop if x reaches -10 or below. if x >= -10 from the previous test, (x -= 2) further decreases the value of x by 2 and tests whether the resulting value is non zero.

  13. C While Loop

    The while loop loops through a block of code as long as a specified condition is true: Syntax. while (condition) { // code block to be executed} In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5: Example. int i = 0;

  14. C while Loop

    Code language: C++ (cpp) How it works: The while statement first evaluates the expression.If the result is non-zero (true), the while statement executes the statement within its body.This cycle continues until the expression becomes zero (or false).. The while statement re-checks the expression at the beginning of each iteration before executing the statement.

  15. C

    There are mainly two types of loops in C Programming: Entry Controlled loops: In Entry controlled loops the test condition is checked before entering the main body of the loop. For Loop and While Loop is Entry-controlled loops. ... In this expression, we assign a loop variable or loop counter to some value. for example: int i=1;

  16. Loops in C: For, While, Do While looping Statements [Examples]

    1. While Loop. In while loop, a condition is evaluated before processing a body of the loop. If a condition is true then and only then the body of a loop is executed. 2. Do-While Loop. In a do…while loop, the condition is always executed after the body of a loop. It is also called an exit-controlled loop. 3.

  17. Loop programming exercises and solutions in C

    C supports three looping statements. for loop; while loop; do…while loop; In this exercise we will practice lots of looping problems to get a strong grip on loop. This is most recommended C programming exercise for beginners. Always feel free to drop your queries, suggestions, hugs or bugs down below in the comments section. I always look ...

  18. while loop

    attr - (since C++11) any number of attributes condition - any expression which is contextually convertible to bool or a declaration of a single variable with a brace-or-equals initializer.This expression is evaluated before each iteration, and if it yields false, the loop is exited.If this is a declaration, the initializer is evaluated before each iteration, and if the value of the declared ...

  22. Understanding Do While Loop in C#

    Understanding Do While Loop in C#. Sreenath Kappoor. May 28, 2024. 6. 0. 0. In a do-while loop, the condition is indeed checked after the code block has been executed. This ensures that the code block is executed at least once, even if the condition is initially false. Do While loop always executes the code and then checks the condition.
