The precise form of the promptis Enter Student Name whose marks are to be edited:Then this function reads the name from standard input.But it must be able to read any name of any size!! 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 terminates. If it is found, the students name followedby : and his/her five marks are displayed (again, 1 must be shownas a space, as in ShowClass()). Let us assume that the student inquestion has marks 10,1,20,15,5Then the function displays a prompt to the user forthe first mark to leave the 1st mark 10 unchanged pressenterotherwise type the new mark and pressenter and reads the user39。 scanf(%d,%d,%d,%d,%d,amp。 i++) { buf[++j] = getchar()。看了書后，最后都一一解決了。}/*endwhile*/return buf。while(1) { for(i = 0。,39。students[i]!=NULL。 return。 marks1[i]=marksx[i]。 printf(Enter Student Name to be deleted from Class List:\n)。free((void*) name)。 marks1[0][0]=marks1[0][1]=marks1[0][2]=marks1[0][3]=marks1[0][4]=0。}/*endwhile*/return 0。fflush(stdout)。N次排序 先進(jìn)行n1次比大小，找到最小的，與第一個(gè)交換，再進(jìn)行n2次。程序由七個(gè)子函數(shù)(creat、edit、extra、imdelete、print、save、)和一個(gè)主函數(shù)（main）組成。 編輯學(xué)生成績基本想法：先讀取要編輯的學(xué)生姓名，然后與所有的學(xué)生姓名進(jìn)行比較，判斷是否在名單內(nèi)，若不在，就輸出不在，否則 就再讀取該學(xué)生的5個(gè)成績到 marks 三、編碼實(shí)現(xiàn)include include include void InsertStudent(char*** students,int*** marks)。menu) != 1){ printf(incorrect entry)。int** marks1。 *marks = marks1。marks1[i][0]=marks1[i][1]=marks1[i][2]=marks1[i][3]=marks1[i][4]=0。 n
