10035 - Primary Arithmetic

[Jan]

Try giving 111 and 799 as input.

[rezaee]

#include <iostream.h>
int main(void)
{int unsigned long a,b;
int s,z;
int unsigned long q[10],d[10];

while(cin>>a>>b)
{if((a==0)&&(b==0))return 0;
else{for(int i=1;i<=9;i++)
{q=0;d=0;}

for(int j=9;j>=1;j--)

{{q[j]=a%10;a=a/10;}{d[j]=b%10;b=b/10;}}
s=0;

for(int k=9;k>=1;k--)

{z=q[k]+d[k];
q[k-1]=q[k-1]+z/10;
if(z>=10)s++;
}
if(s!=0)cout<<s<<" "<<"carry operation."<<endl;
else cout<<"No carry operation."<<endl;}}


}


plz help[/b]

rezaee, your code doesn't pass sample input.

Your output:

No carry operation.
3 carry operation.
1 carry operation.

Sample output:

No carry operation.
3 carry operations.
1 carry operation.

You need plural form of 'operation' if number of operations is more than 1.[/code]

please tell me where is wrong
I have tried many times,but I didn't find wrong.
Thx

=============================================
#include <iostream>

using namespace std;

int test(int n1, int n2)
{
int times=0;
int r_n1,r_n2;
while(n1!=0 || n2!=0)
{
r_n1 = n1 % 10;
r_n2 = n2 % 10;
n1/=10;
n2/=10;
if(r_n1+r_n2 >=10)
{
++times;
n1+=1;
}
}
return times;
}

int main()
{
int num1,num2;
while(cin >> num1 >> num2)
{
if(num1==0 && num2==0)
break;
int times=test(num1,num2);
if(times==0)
cout << "No carry operation." << endl;
else if(times==1)
cout << "1 carry operation." << endl;
else
cout << times << " carry operations." << endl;
}
return 0;
}

Help me , please!

Code: Select all

while(1) 
{ 
gets(num1); 
gets(num2);

Your program will never stop taking inputs even when the end of file is reached.

Change it to:

Code: Select all

while ( gets(num1) != NULL )
gets(num2);

[Waddle]

But I have this:

if( num1[0]==48&&num2[0]==48 )
break;

if i followed what you say, it became "Compile Error".

Did you run your code with your PC?

Each line of input contains two unsigned integers less than 10 digits

gets() reads one line.

ADD: Don't open a new thread if it already exist for the problem.

code removed after got AC....

// here is my code. whats the wrong??????????????????????

#include<stdio.h>
#include<string.h>



void main()

I can't understand what is the wrong actually I did in this code. Please help me . My code is as follows:

Code: Select all

/* p10035 */
/* Primary Arithmetic */

#include<stdio.h>
#include<math.h>
void main()
{
	int n1,n2,r1,r2,s,sum; 
	while(scanf("%d%d",&n1,&n2)!=EOF)
	{
		if(n1==0&&n2==0)
			break;
		s=0;
		while((n1>0)||(n2>0))
		{
			r1=n1%10;
			n1=n1/10;
			r2=n2%10;
			n2=n2/10;
			sum=r1+r2;
			if(sum>9)
				s++;

		}
		if(s==0)
			printf("No carry operation.\n");
		else if(s==1)
			printf("1 carry operation.\n");
		else
			printf("%d carry operations.\n",s);
	}
}
