while 循环: while 循环是一种控制流语句,它允许根据给定的布尔条件重复执行代码。 while 循环可以被认为是一个重复的 if 语句。语法: while(booleancondition) { loop statements... } 流程图: 例子: C实现 #include<stdio.h> intmain() { inti=5; while(i<10){ printf("GFG "); i++; } return0;...
while loop can run indefinitely C. for loop is more complex D. none of the above 相关知识点: 试题来源: 解析 B。本题考查 for 循环和 while 循环的主要区别。while 循环可以根据条件无限运行,而 for 循环通常有明确的循环次数限制。选项 A 不准确,不能说 for 循环总是更快。选项 C 不准确,不一定...
A. For loop is used for definite iterations while while loop is for indefinite iterations. B. For loop is faster than while loop. C. While loop can only be used with numbers while for loop can be used with any data type. D. There is no difference. ...
While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to execute a block of code at least once and then repeatedly execute it if a specific condition is true. What Is A For Loop In C++? A for loop in C++ language...
structure: for(declearation; condition; postLoopCounter) { //Code } The while loop structure: while(condition) { //Code } In terms of effeciency, there doesnt seem to be much difference between for and while loops. But, obviously, the for loops make our code shorter, and easily debug-...
where 'i' is the loop variable The 'do-while' loop can be implemented (in C) as: inti=5; do { printf("%d",i); i--; }while(i>=0); where 'i' is the loop variable. Answer and Explanation:1 Both for loop and while loop can run multiple statements in successive repetition effic...
Q #2) What is the difference between for loop and while loop? Answer:Afor loopis aniterator based loop, which steps through the items of iterable objects likelists,tuples, etc. While awhile loopis acondition-based loop, that executes a block of statements repeatedly as long as its condit...
1、For循环使用场景: (1)主要用来遍历/循环 序列、集合和字典 (2)循环使用 else 语句 在 python 中,for … else 表示这样的意思,for 中的语句和普通的没有区别,else 中的语句会在循环正常执行完(即 for 不是通过 break 跳出而中断的)的情况下执行,while … else 也是一样。 ** 2、while循环用法 ** ...
Difference Between while and do...while LoopThe while loop differs from the do-while loop in one important way — with a while loop, the condition to be evaluated is tested at the beginning of each loop iteration, so if the conditional expression evaluates to false, the loop will never ...
A loop is used for executing a block of statements repeatedly until a given condition returns false. C For loop This is one of the most frequently used loop in C programming. Syntax of for loop: for (initialization; condition test; increment or decrement
