标题:
来一发近100个C言语基本算法案例(低级篇)
使用gcc或g++进行编译,使用gdb进行调试;
上面这些C言语基本算法案例都是经由测试和考证过了的,接待列位利用。
本文是该系列的第一篇,都是一些绝对低级的算法,很合适刚入手下手学C言语的同砚。
1、C言语打印一条语句

/*CProgramtoprintasentence.*/#include<stdio.h>intmain(){printf("CProgramming");/*printf()printsthecontentinsidequotation*/return0;}
复制代码
输入:
CProgramming
复制代码
2、C言语打印用户输出的一个整数
源代码:
#include<stdio.h>intmain(){intnum;printf("Enterainteger:");scanf("%d",&num);/*Storingaintegerenteredbyuserinvariablenum*/printf("Youentered:%d",num);return0;}
复制代码
输入:

但不会命令而成为高手也是不可能的.这就好比学英语,什么语法都不懂,只捧着单词手册背单词是学不会英语的,但是没有单词词汇量英语水平也提不高的。

最后一部分:算是高级一些的主题,总感觉书的这一部分翻译的不太好,读起来完全没有前面几章顺畅,像多重继承什么的,如果觉得太难理解,看的时候放一放,改天等你用到的时候,再来看看是怎么回事。

用的vector,而很少使用了数组。当然在我现在的能力范围内,还很难驾驭vector,毕竟数组当年也是我的最爱,相比于更加难缠的指针控制来说。
