1.

#include <stdio.h>

int main()

{

int a;

scanf("%d",&a);

int ans=60*60*1.2/a;

printf("%d",ans);

}

2.進階題：區間測速-超速之王

#include <stdio.h>

int main()

{

int a=0,b=9999;

for(int i=1;i<=10;i++)

{

int c;

scanf("%d",&c);

if(c<b)

{

a=i;

b=c;

}

}

int ans=60*60*1.2/b;

printf("%d %d",a,ans);

}

3.UVA10929：You can say 11

#include <stdio.h>

#include <string.h>

int main()

{

char b[1001];

while(scanf("%s",b)==1)

{

long int e=strlen(b);

if(b[0]=='0')break;

int c=0,d=0;

for(int i=0;i<e;i++)

{

if(i%2==0)c+=b[i]-'0';

else d+=b[i]-'0';

}

if(c%11==d%11)printf("%s is a multiple of 11.\n",b);

else printf("%s is not a multiple of 11.\n",b);

}

}

4.老師複習每個技巧, 技巧: 把字母,變成數值 印出來

#include <stdio.h>

int main()

{

    char c;

    scanf("%c",&c);

    printf("%c %d\n",c,c);

    printf("%d\n",c-'0');

}

5.老師複習每個技巧, 技巧: 字串的迴圈怎麼寫, 老師的示範, 做一次

#include <stdio.h>

int main()

{

    char a[30]="ha ha ha";

    for(int i=0;a[i]!=0;i++)

    {

        char c=a[i];

        printf("==%c==%d==\n",c,c);

    }

}
