C语言简单代码

例一：//按"1"、"2"控制

#include"stdio.h"

#include"conio.h"

voiddelay(intx)

{inty;

while(x--)

for(y=0;y<125;y++)

{;}

}

voidpout(inti)

{

if(i==1)

{

printf("%c",26);

delay(1000000);

printf("\b%c",0);

}

if(i==2)

{

printf("\b%c",0);

printf("%c",27);

delay(1000000);

printf("\b%c\b\b",0);

}

}

intmain()

{

inta=1;

while(1)

{

if(kbhit())

{

a=getch()-48;

}

pout(a);

}

return0;

}

例二：猜一个1~到100的数

#include<iostream>

#include<cstdlib>

#include<ctime>

usingnamespacestd;

intmain()

{

srand(time(0));//生成随机数生成器种子

inttheNumber=rand()%100+1;//1-100的随机数

inttries=0,guess;

cout<<"\tWecometoGuessMyNumber\n\n";

do

{

cout<<"Enteraguess:";

cin>>guess;

++tries;

if(guess>theNumber)

cout<<"Toohigh!\n\n";

if(guess<theNumber)

cout<<"Toolow!\n\n";

}while(guess!=theNumber);

cout<<"\nThat'sit!Yougotitin"<<tries<<"guess!\n";

return0;

}
