please help me i m making program which takes a number from user and then make greates 3 digit number from the digits of that number
ex. if user type 57149 then output should be 975 because this is the greatest number that can be formed by digits. i tried below code but when i type number nothing is shown
above program even not printing the digits of number. so i didnt type further but once i get code to separate digits i will sort the array and will print first 3 numbers because we want 3 digit largest numberCode:#include <stdio.h> #include <stdlib.h> int main() { int a[20],n,no,i,cnt=0; printf("Enter a no."); scanf("%d",&no); n=no; while(no!=0) { no=n/10; cnt++; } for(i=0;i<cnt;i++) { a[i]=n%10; n=n/10; if(n==0) break; } for(i=0;i<cnt;i++) printf("%d\n",a[i]); return 0; }
but first someone correct this code so it can separate digits please help me
thanks
