Division of Large Numbers in C Program
Solution:
#include<stdio.h>
#include<math.h>
#include<stdlib.h>
#include<string.h>
#define MAX 10000
char * division(char [],unsigned long);
int main(){
char a[MAX];
unsigned long b;
char *c;
printf("Enter the divdend : ");
scanf("%s",a);
printf("Enter the divisor : ");
scanf("%lu",&b);
c = division(a,b);
printf("\nQuotient of the division : ");
printf("%s",c);
return 0;
}
char * division(char a[],unsigned long b){
static char c[MAX];
int la;
int i,k=0,flag=0;
unsigned long temp=1,reminder;
la=strlen(a);
for(i=0;i<=la;i++){
a[i] = a[i] - 48;
}
temp = a[0];
reminder = a[0];
for(i=1;i<=la;i++){
if(b<=temp){
c[k++] = temp/b;
temp = temp % b;
reminder = temp;
temp =temp*10 + a[i];
flag=1;
}
else{
reminder = temp;
temp =temp*10 + a[i];
if(flag==1)
c[k++] = 0;
}
}
for(i=0;i<k;i++){
c[i]=c[i]+48;
}
c[i]= '\0';
printf("Remainder of division: %lu ",reminder);
return c;
}
