This repeats until the condition becomes false. Do while loops check the condition after the block of code is executed. This control structure can be known as a post-test loop. This means the do-while loop is an exit-condition loop. However a while loop will test the condition before the code within the block is executed.
Pascal has two forms of the while loop, while and repeat. While repeats one statement (unless enclosed in a begin-end block) as long as the condition is true. The repeat statement repetitively executes a block of one or more statements through an until statement and continues repeating unless the condition is false. The main difference between ...
The following is a C-style While loop. It continues looping while x does not equal 3, or in other words it only stops looping when x equals 3. However, since x is initialized to 0 and the value of x is never changed in the loop, the loop will never end (infinite loop).
To ward off dementia, older adults may want to spend more time reading, praying, crafting, listening to music and engaging in other mentally stimulating behaviors, a new study says.
A California man died and a Good Samaritan is facing serious injuries after being attacked by dogs last week. According to a statement from the San Diego Humane Society obtained by USA TODAY, the ...
For another example, the while rule can be used to formally verify the following strange program to compute the exact square root x of an arbitrary number a —even if x is an integer variable and a is not a square number:
Steps that older adults can take to reduce their risk of falls and fractures include getting screened for osteoporosis, especially for women 65 and older, Rao said, and getting regular exercise.
In the C programming language, Duff's device is a way of manually implementing loop unrolling by interleaving two syntactic constructs of C: the do-while loop and a switch statement. Its discovery is credited to Tom Duff in November 1983, when Duff was working for Lucasfilm and used it to speed up a real-time animation program.
