C program to find the lowest digit of a number?

Answer 1

#include<stdio.h>

#include<conio.h>

void main()

{

int n,d[10],i,k,s;

clrscr();

printf("enter the number..:");

scanf("%d",&n);

for(i=0,t=n;t>0;i++)

{

d[i]=t%10;

t=t/10;

}

k=i;

s=d[0];

for(i=1;i<k;i++)

{

if(d[i]<s)

s=d[i];

}

printf("\n The smallest digit is...%d",s);

getch();

}

Answer 2

#include <stdio.h>

int main()

{

int input;

printf ("Enter a number ");

scanf ("%d", &input);

int digit = 0;

while (1)

{

if ( (input % 10 > 0) (input /10 > 0) )

{

digit += input % 10;

input /= 10;

} else if ( digit > 9 )

{

input = digit;

digit = 0;

}

else

{

break;

}

}

printf("Your input is condensed to %d \n\n", digit);

return 1;

}

Answer 3

// returns the largest digit of num in the given base (default is base 10, decimal)int largest_digit (int num, int base=10) {

int current, digit;

current = num%base; // store least-significant digit (current largest)

while (num/=base) { // repeat until num is zero

digit=num%base; // store least-significant digit

if (current<digit) { // compare

current=digit; // update current largest

}

}

return current;

}

Example usage:

int main (void) {

int d1 = largest_digit (42); // 4

int d2 = largest_digit (123); // 3

int d3 = largest_digit (741863); // 8

int d4 = largest_digit (0xABCD, 16); // 13

return 0;

}

Note that although 13 has two digits, 13 is the decimal value of D, the largest digit in 0XABCD.
