Question

I have the question and the answers can someone explain the concepts to solve these problems and explain why the answers are what they are 

consider the decleration below

 

struct rec (char name[20]; float salary: } item, recs[10],"temp; Write the C statement(s) to do each of the following: 1. Read from the keyboard a value for the salary of the variable item. scanf("%f",&item.salary); 2. Assign to the name field of item the string "Schemp". strcpy(item.new, "Schemp"); 3. Assign to the 2nd character in the name field of the first element of recs the letter B. recs[0].name [1] = 'B'; 4. Assuming that the address of a properly allocated variable of type struct rec has been stored in temp, assign to the salary field of the variable the value 1000. temp -> salary = 1000.; 5. Declare fto be a pointer to a function that returns an integer and has a single argument of type struct rec.
