There is not much difference between for and while loops. the for loops can be called a enhanced form of while loops. The for loop structure: for(declearation; condition; postLoopCounter) { //Code } The while loop structure: while(condition) { //Code } In terms of effeciency, there ...
C语言基础——循环性结构 (1)while表达式 while(表达式) {循环语句组} (2) 在循环体中,循环变量要有变化,并且使得循环条件可以为假。以跳出循环,避免出现“死循环”。(3) 循环变量要有初值。 (4)do—while语句 do {循环语句组} while(表达式); 注意:(1)do—while语句是先执行语句序列一次,后判断表达式...
Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? What is a key difference between a do/while loop and a while loop? A do/while loop will execute the code block at least once, even if the condition is false. A do/while loop ...
