Pleade solving manually. Write a function that takes a string $($i$.$e$.,$ a char array$)$ as input and returns the number of words within it$.$ Assume that words are delimited by the blank space character $\text{'},$ Assume that the input array ends with the EOS $($end$-$of$-$string$)$ character with value $0.$ Code against multiple spaces delimiting the same two words. Code against a completely empty string, in which case your code should return $0.$

Do not use the string library string. $h$ in your answer.

Examples: word count for "hello world" is $2,$ same for $"$ hello world" is still $2,$ same for $""$ is $0.$

The signature of your function will be as shown below.

int countNumWords$($char$*$ arr$)$
