11777 - Automate the Grades

Post by @mjad » Sat Apr 23, 2011 10:43 am

please help me

Code: Select all

#include<stdio.h>

int main() {
    int ks =0,term1,term2,term3, term4, at1,at2,at3,total, min ,n;
    //freopen("input.txt", "r",stdin);

    scanf("%d", &n);
    for( ; n > 0; n--) {
        total = 0;
        ks++;
        scanf("%d%d%d%d%d%d%d", &term1, &term2, &term3, &term4, &at1, &at2,&at3);
        total = term1+term2+term3+term4;
        min = at1;
        min = min < at2 ? min : at2;
        min = min < at3 ? min : at3;

        total = total + (( at1 + at2 + at3 - min) / 2.0);
        if( total >= 90)
            printf("Case %d: %c\n",ks,'A');
        else  if( total >= 80)
            printf("Case %d: %c\n",ks,'B');
        else if( total >= 7)
            printf("Case %d: %c\n",ks,'C');
        else if( total >= 6)
            printf("Case %d: %c\n",ks,'D');
        else
            printf("Case %d: %c\n",ks,'F');
    }
    return 0;

Re: 11777 why no AC?

Post by robot » Thu Apr 28, 2011 7:49 pm

please check ur code condition
else if( total >= 7) ---> else if( total >= 70)
printf("Case %d: %c\n",ks,'C');
else if( total >= 6) ----> else if( total >= 60)
printf("Case %d: %c\n",ks,'D');

why it gives wrong answer


#include<stdio.h>
int main()
{
int a,b,c,d,e,f,g,i,t,sum,total;
scanf("%d",&t);
for(i=1;i<=t;i++)
{
scanf("%d%d%d%d%d%d%d",&a,&b,&c,&d,&e,&f,&g);
if(e<f&&e<g||e==f&&f==g)
sum=(f+g)/2;
else
{
if(f<e&&f<g||e==f&&f==g)
sum=(e+g)/2;
else
{
if(g<e&&g<f||e==f&&f==g)
sum=(e+f)/2;
}
}
total=a+b+c+d+sum;
if(total>=90)
printf("Case %d: %c\n",i,'A');
else if(total>=80&&total<90)
printf("Case %d: %c\n",i,'B');
else if(total>=70&&total<80)
printf("Case %d: %c\n",i,'C');
else if(total>=60&&total<70)
printf("Case %d: %c\n",i,'D');
else if(total<60)
printf("Case %d: %c\n",i,'F');
}
return 0;
}

The third case of the sample input is: 20 20 30 10 18 0 0. Your code prints A, it should be B. 20+20+30+10+(18+0)/2=89.

You're not printing the case number correctly if they get an F.
