# Check if two numbers have same number of digits

Given two integers **A** and **B**, the task is to check whether both the numbers have equal number of digits.

**Examples:**

Input:A = 12, B = 1

Output:No

Input:A = 20, B = 99

Output:Yes

**Approach:** While both the numbers are > 0, keep dividing both the numbers by 10. Finally, check if both the numbers are 0. If any one of them is not 0 then they had unequal number of digits.

Below is the implementation of the above approach:

## C++

`// C++ implementation of the approach ` `#include <bits/stdc++.h> ` `using` `namespace` `std; ` ` ` `// Function that return true if A and B ` `// have same number of digits ` `bool` `sameLength(` `int` `A, ` `int` `B) ` `{ ` ` ` `while` `(A > 0 && B > 0) { ` ` ` `A = A / 10; ` ` ` `B = B / 10; ` ` ` `} ` ` ` ` ` `// Both must be 0 now if ` ` ` `// they had same lengths ` ` ` `if` `(A == 0 && B == 0) ` ` ` `return` `true` `; ` ` ` `return` `false` `; ` `} ` ` ` `// Driver code ` `int` `main() ` `{ ` ` ` `int` `A = 21, B = 1; ` ` ` ` ` `if` `(sameLength(A, B)) ` ` ` `cout << ` `"Yes"` `; ` ` ` `else` ` ` `cout << ` `"No"` `; ` ` ` ` ` `return` `0; ` `} ` |
