do you feel your code Beginner, C, URI 12 comments

Before seeing the solution make sure that you tried enough. Don’t paste the whole code, just find out the logic. If you stuck in trouble, just inform me on comment.

#include <stdio.h>
int main()
{
    double a,b,c,d,e,f,g,h=1,x=1,y=1,z=1;
    for(h=1;;h=1,x=1,y=1,z=1)
    {
        scanf("%lf",&a);
        if(a<0 || a>10)
        {
            printf("nota invalida\n");

        printf("media = %.2lf\n",c);
        printf("novo calculo (1-sim 2-nao)\n");

why did you use the variables x,y and z ? And i don't understand this increment, can you explain too?

why my code is shown wrong........everything is looking clear and acceptable........but it is showing wrong..

#include
int main()
{
int i,X=0;
double a,c=0;
for(i=0;;i++)
{
scanf("%lf",&a);
if(a>=0&&a<=10)
{
c=c+a;
X++;
}
else
{
printf("nota invalida\n");
}
if(X==2)
{
printf("media = %.2lf\n",c/2);
X=0;
{
c=0;
break;
}

}

}
for(i=0;;i++)
{
printf("novo calculo (1-sim 2-nao)\n");
scanf("%lf",&a);
if(a==1)
{

for(i=0;;i++)
{
scanf("%lf",&a);
if(a>=0&&a<=10)
{
c=c+a;
X++;
}
else
{
printf("nota invalida\n");
}
if(X==2)
{
printf("media = %.2lf\n",c/2);
X=0;
break;
}
}

}
else if(a==2)
break;
}

return 0;
}

note: goto statement make your code inefficient. :)
#include
int main()
{
float x,sum=0.0;
int y=0,t,l;
l:
while(1)
{
if(y==2)
{
printf("media = %.2f\n",sum/2.00);
printf("novo calculo (1-sim 2-nao)\n");
while(scanf("%d",&t)==1)
{
if(t<1 || t>2)
{
printf("novo calculo (1-sim 2-nao)\n");
continue;
}
if(t==1)
{
y=0;
sum=0;
goto l;
}
else
goto m;
}
m:
break;
}
scanf("%f",&x);
if(x>=0.0 && x<=10.0)
{
y++;
sum=sum+x;
}
else
printf("nota invalida\n");
}
return 0;
}

its more simple

#include
int main()
{
float score,sum=0,count=0,com;
while(1)
{
if(count==2)
break;
scanf("%f",&score);
if(score>=0&&score<=10)
{
count++;
sum = sum + score;
}
else
printf("nota invalida\n");
}
printf("media = %.2f\n",sum/2);

while(1)
{
printf("novo calculo (1-sim 2-nao)\n");
scanf("%f",&com);
if(com==2)
break;
if(com!=1&&com!=2)
continue;
if(com==1)
{
float score,sum=0,count=0,com;
while(1)
{
if(count==2)
break;
scanf("%f",&score);
if(score>=0&&score<=10)
{
count++;
sum = sum + score;
}
else
printf("nota invalida\n");
}
printf("media = %.2f\n",sum/2);

}
}
return 0;
}

class Program
{
static void Main(string[] args)
{

{
bool a, b; double soma = 0.0, media = 0.0, n1, n2; int x;

do
{

do
{
n1 = double.Parse(Console.ReadLine(), CultureInfo.InvariantCulture);
if (n1 > 0.0 && n1 <= 10.0)
{
a = true;
soma = n1;
}
else
{
a = false;
Console.WriteLine("nota invalida");
}
} while (a == false);

do
{
n2 = double.Parse(Console.ReadLine(), CultureInfo.InvariantCulture);
if (n2 > 0.0 && n2 <= 10.0)
{
b = true;
soma = n1 + n2;
}
else
{
b = false;
Console.WriteLine("nota invalida");
}
} while (b == false);

media = soma / 2.0;
Console.WriteLine("media = " + media.ToString("F2", CultureInfo.InvariantCulture));

do
{
Console.WriteLine("novo calculo (1-sim 2-nao)");
x = int.Parse(Console.ReadLine());
} while (x < 1 || x > 2);

} while (x != 2 || x == 1);
}

}
}

eu encadeei alguns "do" pra dar certo em C#.

Isn't it is the easiest way to solve in C.
#include

int main()
{
double a,b=0,c=0,s=0;
int x;
while(scanf("%lf",&a))
{
if(a>=0&&a<=10)
{
b++;
s+=a;
}
else printf("nota invalida\n");
if(b==2)
{
printf("media = %.2lf\n",s/2);
s=0;
printf("novo calculo (1-sim 2-nao)\n");
while(scanf("%d",&x))
{
if(x==1)
{
b=0;
break;
}
else if(x==2)
{
c=x;
break;
}
else printf("novo calculo (1-sim 2-nao)\n");
}
if(c==2) break;
}
}
return 0;
}//end of line
