<Codesignal> evenDigitsOnly

Easy

Check if all digits of the given integer are even.

Example

• For n = 248622, the output should be
  evenDigitsOnly(n) = true;
• For n = 642386, the output should be
  evenDigitsOnly(n) = false.

Input/Output

• [execution time limit] 0.5 seconds (c)

• [input] integer n

  Guaranteed constraints:
  1 ≤ n ≤ 10^9.

• [output] boolean

  • true if all digits of n are even, false otherwise.

[C] Syntax Tips

// Prints help message to the console
// Returns a string
char * helloWorld(char * name) {
    char * answer = malloc(strlen(name) + 8);
    printf("This prints to the console when you Run Tests");
    strcpy(answer, "Hello, ");
    strcat(answer, name);
    return answer;
}

Solution

bool evenDigitsOnly(int n)
{
	while(n>0)
	{
		if(n%2==1)
			return false;
		n/=10;
	}

	return true;
}
