help to solve my problem

hey hi...i was supposed to read a 4 digit number and then find tje sum of its digts.....tell me what went wrong.....keep it too simple.....

Code:

#include<stdio.h>
main()
{
int num,a,b,c,d,e;
printf("enter the number");
scanf("%d",&num);
a=(num/1000);
b=num/100;
c=num/10;
d=num%1000;
e=a+b+c+d;
printf("\n%d",&a);
printf("\n%d",&b);
printf("\n%d",&c);
printf("\n%d",&d);
printf("the sum is %d",&e);
return(0);
}

 

Hi!

1. You use address of variables when you print numbers (&).
2. Take any number and try to calculate manually using your formula. It doesn't work.

Try to use loop to calculate the sum.

 

i think this would help u :-

Code:

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int num;
int a,b,c,d,e,f,g,h;
printf("enter a no");
scanf("%d",&num);
a=num/1000;
printf("d is %d \n",a);
b=num/100;
e=b%10;
printf("e is %d \n",e);
c=num/10;
f=c%10;
printf("b is %d \n ",f);
d=num%1000;
g=d%10;
printf("a is % d \n",g);
h=a+e+f+g;
printf ("the sum is%d ",h);
getch();
}

 

hello... it is the solution for your problem...

Code:

#include<stdio.h>
#include<conio.h>
void main(void)
{
clrscr();
float num,a,b,c,d,e;
printf("enter the number");
scanf("%f", &num);
a= num/1000;
b=num/100;
c=num/10;
d=num/1000;
e=a+b+c+d;
printf("\n%1f", a);
printf("\n%1f", b);
printf("\n%1f", c);
printf("\n%1f", d);
printf("\nthe sum is %f", e);
getch();
}

 

Code:

#include<stdio.h>
#include<conio.h>
void main(void)
{
clrscr();             
             int num,a,b,c,d,e;

	printf("enter a 4 digit number : ");  //1234
	
	scanf("%d",&num);

	a=num/1000;                                       //1
	b=(num - (a*1000))/100;                       //(1234 - 1*1000)/100 = 234/100 = 2
	c=(num - (a*1000) - (b*100))/10;          //(1234 - 1*1000 - 2*100)/10 = 34/10 = 3 
	d=(num - (a*1000) - (b*100) - (c*10))/1; //(1234 - 1*1000 - 2*100 - 3*10)/1 = 34/1 = 1

	e=a+b+c+d;
	
	printf("\n%d",a);
	printf("\n%d",b);
	printf("\n%d",c);
	printf("\n%d",d);
	printf("\nthe sum is %d\n",e);

            return 0;
}

 

its the solution.......!!!

Code:

#include<stdio.h>
#include<conio.h>
void main(void)
{
int a,b,c,d,e,num;
clrscr();
printf("enter a 4 digit number : ");
scanf("%d",&num);
a=num/1000;
b=(num - (a*1000))/100;
c=(num - (a*1000) - (b*100))/10;
d=(num - (a*1000) - (b*100) - (c*10))/1;

e=a+b+c+d;

printf("\n%d",a);
printf("\n%d",b);
printf("\n%d",c);
printf("\n%d",d);
printf("\nthe sum is %d\n",e);

getch();
}
