One-Line while Loops. As with an if statement, a while loop can be specified on one line. If there are multiple statements in the block that makes up the loop body, they can be separated by semicolons (; ): Python. >>> n = 5 >>> while n > 0: n -= 1; print(n) 4 3 2 1 0. This only works with simple statements though. A while loop is a command in computer programming that executes another set of commands repeatedly until a certain condition is met.

And in asm, use the do {}while () loop structure whenever possible, for the same reason compilers do: code runs faster with fewer instructions inside the loop. (Usually peeling the run-zero-times check is better than jumping to the bottom of the loop like you're doing here in your while loop.) – Peter Cordes.The total time complexity of the algorithm can be calculated by multiplying the number of iterations of each loop by the time complexity of each iteration and taking the maximum of all possible combinations. For example, consider the following code: for i in range(n): for j in range(m): # some constant time operation.The do - while loop is one of the most often used types of loops in C. In C, do and while keywords are used together to form a loop. The other looping keywords are while and for.
