简单的猜数2

1.无限猜数版

1.1 

#include 
#include 
#include 

int main()
{
    int magic;
    int guess;
    unsigned int seed;
    int counter;

    srand(time(NULL));

    counter=0;
    magic=rand()%100+1;
    //printf("%dn",magic);答案

    do{
    printf("Please guess a number:");
    scanf("%d",&guess);
    counter++;
    if(magic>guess)
    {
        printf("Wrong.Too small.n");
    }
    if(magic 
1.2
 
#include 
#include 
#include 

int main()
{
    int magic;
    int guess;
    unsigned int seed;
    int counter;

    srand(time(NULL));

    counter=0;
    magic=rand()%100+1;
    //printf("%dn",magic);答案

    do{
    printf("Please guess a number:");
    scanf("%d",&guess);
    counter++;
    if(magic>guess)
    {
        printf("Wrong.Too small.n");
    }
    if(magic 
2.限制猜数次数版
 
10次
 
#include 
#include 
#include 

int main()
{
    int magic;
    int guess;
    unsigned int seed;
    int counter;

    srand(time(NULL));

    counter=0;
    magic=rand()%100+1;
    printf("%dn",magic);

    do{
    printf("Please guess a number:");
    scanf("%d",&guess);
    counter++;
    if(magic>guess)
    {
        printf("Wrong.Too small.n");
    }
    if(magic 
3.错了重来版
 
#include 
#include 
#include 

int main()
{
    int magic;
    int guess;
    unsigned int seed;
    int counter;
    char ch;

    srand(time(NULL));

    do{
        counter=0;
        magic=rand()%100+1;
        //printf("%dn",magic);答案

    do{
    printf("Please guess a number:");
    scanf("%d",&guess);
    counter++;
    if(magic>guess)
    {
        printf("Wrong.Too small.n");
    }
    if(magic 
ch的%c前要有一个空格。把前面的回车消除掉。
 
 
4.好好输入版 
 
以上如果输入的不是数字会产生错误。
 
输入q。
 
 
防止输入非法字符。
 
printf("Please guess a number:");
    a=scanf("%d",&guess);

    while(a!=1)
    {
        while(getchar()!='n');3
        printf("Please guess a number properly:");
        a=scanf("%d",&guess);
    }
 
 完整↓
 
#include 
#include 
#include 

int main()
{
    int magic;
    int guess;
    unsigned int seed;
    int counter;
    char ch;
    int a;

    srand(time(NULL));

    do{
        counter=0;
        magic=rand()%100+1;
        //printf("%dn",magic);答案

    do{
    printf("Please guess a number:");
    a=scanf("%d",&guess);

    while(a!=1)
    {
        while(getchar()!='n');3
        printf("Please guess a number properly:");
        a=scanf("%d",&guess);
    }

    counter++;
    if(magic>guess)
    {
        printf("Wrong.Too small.n");
    }
    if(magic
