Thus you haveto allocate memory (using malloc()) to read the input into, and ifit is not big enough, must use realloc() to extend it. You are notallowed to allocate more than 10 bytes in one allocation or extendyour segment by more than 10 bytes in one call to realloc().Do not forget to deallocate the memory before exiting the function!Note that this part of the code is the same as in InsertStudent()and DeleteStudent(), so you can either copy it or write a functionthat would do it for all three.If the student is not found in the array students, a warning messagestudent xxx not in the Class List is displayed on the screen andthe function term
