MySQL创建存储过程,实现累加运算,计算 1+2+…+n 等于多少。具体的代码如下 1、实现计算1+2+3+…+n的和 DELIMITER // CREATE PROCEDURE sp_add_sum_num(IN n INT) BEGIN DECLARE i INT; DECLARE sum INT; SET i = 1; SET sum = 0;WHILE i <= n DO SET
一、题目; 二、N-S流程图; 三、运行结果; 四、源代码; # define _CRT_SECURE_NO_WARNINGS# include <stdio.h>int main(){//初始化变量值;int i = 0;int j = 0;int n = 5;int result = 0;int sum = 0;//运算;for (i = 1; i <= n; i++)
