FIND OUT GENERIC ROOT OF A NUMBER By C PROGRAM


C program for generic root

#include<stdio.h>
int main(){

long int num,sum,r;
printf("\nEnter a number:-");
scanf("%ld",&num);

while(num>10){
sum=0;
while(num){
r=num%10;
num=num/10;
sum+=r;
}
if(sum>10)
num=sum;
else
break;
}
printf("\nSum of the digits in single digit is: %ld",sum);
return 0;
}


C code for calculation of generic root in one line

#include <stdio.h>
int main(){         
int num,x;
printf("Enter any number: ");
scanf("%d",&num);
printf("Generic root: %d",(x=num%9)?x:9);
return 0;
}

Sample output:
Enter any number: 731
Generic root: 2

Meaning of generic root:
It sum of digits of a number unit we don't get a single digit. For example:
Generic root of 456: 4 + 5 + 6 = 15 since 15 is two digit numbers so 1 + 5 = 6
So, generic root of 456 = 6

there is an easier way to solve this...

This program prints the sum if it is 10
but 10 should be as 1+0=1 for the single digit sum


int sumofdigits(int num)
{
int sum=0;
int r;
while(num>9)
{
sum=0;
while(num)
{
r=num%10;
num/=10;
sum+=r;
}
if(sum>9)
num=sum;
}
return sum;
}
void main()
{
int num;
printf("Enter the number:");
scanf("%d",&num);
printf("%d",sumofdigits(num));
}

One logic may be like this:
(num-1)%9 +1;

int r,num=90,sum=0;
if(num>=10)
{
while(num!=0)
{
r=num%10;
num=num/10;
sum+=r;
}
printf("sum=%d",sum);
}
else
printf("sum=%d",num);
return 0;
}
