Question

Write a program that accepts an input string from the user, and determines

how many times a user-specified character appears within the string. (Hint:

Look up the 's' option of the input function using the MATLAB Help

Browser.)

Actually you have to get 2 things from the user:

The user-specified input string to search in

The user-specified character to search for (in order to count how many times it occurs)

If the user enters a string instead of a single character you should just use the first character of the string.

Example Run #1
     Enter a string to search: Look for me please
     Enter a character to look for: e
     e was found 3 times in Look for me please

Example Run #2
            Enter a string to search: This is another test

Enter a character to look for: stop

s was found 3 times in This is another test

Example Run #3
            Enter a string to search: This is another test

Enter a character to look for: z

z was found 0 times in This is another test
