Question

Write a C program accepts an integer and prints the integer after removing 0's at last.​

Answer 1

$\texttt{\textsf{\large{\underline{Solution}:}}}$

The given co‎‎de is written in C.

#include <stdio.h>

int main() {

   int n;

   printf("Enter a number: ");

   scanf("%d",&n);

   while(n%10==0)

       n/=10;

   printf("The number after removing zeros at last is: %d",n);

   return 0;

}

$\texttt{\textsf{\large{\underline{Explanation}:}}}$

• If a number is divisible by 10, then it must have 0 at its end. Here, the loop iterates till n%10==0 is true i.e., it iterates only when the number is divisible by 10. After each iteration, number is divided by 10 so as to remove the zeros.
