Consonent vowel pair

The program must accept a string S as the input. The program must print all the pairs having a consonant followed by a vowel in the string S (in the order of occurrence) as the output.

Note: The string S always contains at least one pair having a consonant followed by a vowel.

Boundary Condition(s): 2<= Length of S <= 100

Input Format:

The first line contains the string S.

Output Format:

The first line contains all the pairs having a consonant followed by a vowel separated by a space.

Example Input/Output 1:

Input:
volcano
Output:
vo ca no
Explanation:
The string “volcano” contain three pairs having a consonant followed by a vowel So the pairs vo ca and no are printed as the output.

Example Input/Output 2:

Input
TELEVISION
Output
TE LE VISI

	int u=strlen(a);
	for (int i=0;i<u;i++)

	{

			printf("%c%c ",a[i],a[i+1]);
