Question :

Write a C function which prints a frequency histogram of words in a given sentence.

The words in the given string may contain a mixture of lower and upper case letters in which case your function should be able to identify them and treat as the same words.

For example, the words "Happy", "happy" and "HAPPY" are all the same. You can assume that all words are separated by single spaces and each word can contain at most 10 characters.

Each line of your output histogram should contain a unique word in a column that is 10 characters wide, followed by a number of "+" signs equal to total occurrence of that word in the given sentence. The function should have the following prototype:
void printFrequencyHistogram(char * sentence);

Sample input strings and outputs are as follows.
char sentence1[] = "I am the ONE and only one and I am who I am";
printFrequencyHistogram(sentence1); // should print as below:

I +++
am +++
the +
one ++
and ++
only +
who +
