1for(inti=1;i<=10;++i)2{3输出若干空格4输出若干M5换行6} 略加思考,列出在第i行,其空格数,M数与i的关系为: 即第i行的空格数为i-1个,M数为21-2i。即在第i行输出空格和输出M字符的内循环分别为: 1for(intj =1; j <= i; ++j)2cout <<"";3for(intk =1; k <=21-2* i; ++k)4c...
In programming, a loop is used to repeat a block of code until the specified condition is met. C programming has three types of loops: for loop while loop do...while loop We will learn about for loop in this tutorial. In the next tutorial, we will learn about while and do...while...
Let’s take a look at the example: First you must always initialize the counter before the while loop starts ( counter = 1). Then the while loop will run if the variable counter is smaller then the variable “howmuch”. If the input is ten, then 1 through 10 will be printed on the...
1. " For" loops execute blocks of code over and over again. 2. It is clear to a developer exactly how many times the loop will execute before the loop starts. 3. The Syntax of the for loop is almost same to other programming languages. For loop repetition statement Here are some exam...

C语言:‘for‘ loop initial declarations are only allowed in C99 mode 求最大公约数之 穷举法 mistake: because: 只允许在C99模式下使用‘for’循环初始化声明 solution:不在for()中初始化生命变量

使用gcc编译代码是报出 error: 'for' loop initial declarations are only allowed in C99 mode note: use option -std=c99 or -std=gnu99 to compile your code 错误，这是因为在gcc中直接在for循环中初始化了增量：这是因为gcc基于c89标准，换成C99标准就可以在for循环内定义i变量了：gcc src....
