Final answer:
The student is asked to create a function named right_align that takes a constant pointer to a source string and two other parameters, to right-align the text within the string by determining the necessary number of leading spaces.
Step-by-step explanation:
The question asks to write a function called right_align that will right-align text within a string. The function should take three parameters, one of which is a constant pointer to a source string (a character array indicating the first character of the string). While the question does not provide complete details, the general idea is to manipulate the string so that the text appears right-aligned when printed or displayed in a fixed-width context.
To accomplish this, the function must calculate the length of the string and then determine how many spaces to prepend so that the text aligns to the right. This involves measuring the width of the display or desired field and padding the string with spaces accordingly. For example, if the display width is 20 characters and the string is 15 characters long, five spaces would be added to the beginning of the string.
This function would be useful in programming scenarios where text formatting is essential, such as generating reports, creating command-line interfaces, or building text-based user interfaces. The implementation of this function would involve using string manipulation techniques available in the programming language being used.
