expand the code below with the following questions #include #include int cent50 = 0; int cent20 = 0; int cent10 = 0; int cent05 = 0; //Function definition void calculateChange(int change) {     if(change > 0) {          if(change >= 50) {             change -= 50;             cent50++;         }         else if(change >= 20) {            change -= 20;             cent20++;         }         else if(change >= 10) {             change -= 10;             cent10++;         }          else if(change >= 05) {            change -= 05;             cent05++;         }         calculateChange(change);     } } //Define the function void printChange() {     if(cent50)         printf("\n50 Cents : %d coins",  cent50);      if(cent20)         printf("\n20 Cents : %d coins",  cent20);      if(cent10)         printf("\n10 Cents : %d coins", cent10);     if(cent05)         printf("\n05 Cents : %d coins", cent05);          cent50 = 0; cent20 = 0; cent10 = 0; cent05 = 0; } //Function's definition int TakeChange() {     int change;     printf("\nEnter the amount : ");     scanf("%d", &change);     return change; } //main function int main() { //call the function int change = TakeChange(); //use while-loop to repeatedly ask for input to the user while(change != -1)     {     if((change % 5)==0)     {      if(change >= 5 && change <=95 ){       calculateChange(change); //Calculate coins   }   else {    printf("\nPlease Enter the value between 5 and 95:");   }    }  else  {   printf("\nPlease Enter the valid value:");  } //Print coins printChange(); printf("\nEnter the amount to continue or Enter -1 to exit: "); scanf("%d", &change);      } return 0; }   The program takes two inputs at a time (this is to be read from a file; see below). The name of a person, and the coin value as an integer in the range 5 to 95 (this data should be encapsulated using the above mentioned struct). You can assume that the data in the input file will have names that are one word strings, coin values that are always evenly divisible by 5 (integer division), and these two fields are space separated. An example input is: Jane 30 This input line indicates that 30 cents change is to be given to Jane. Output change values need to be in multiples of 50, 20, 10 and 5 cents. The program should aim to give as much of the higher valued coins as possible. A poor solution for an input of 30 cents is to give six 5 cent coins. A better solution is to give a 20 cent coin and a 10 cent coin. Input to the program comes from a data file called coins.txt (this should be obtained from command line when invoking the program). There should be 10 input lines like the example above. Each record is to be stored in a struct; an array of such structs is to store all data read from the file (i.e. all 10 records). It is possible to have the same name repeated in the data file but the coin values should be different. When the name is the same, it would mean the same individual. In such a case, your program would need to add up the coin amounts to obtain a total amount for that individual (this would occur after all records have been stored into your data structure, but before computing the change to be given). Note that in this scenario, the total amount for an individual may end up being over 100 or 200 or more cents. Once your program has read in the data from coins.txt, it will close coins.txt first, and then show a console screen menu as illustrated below. The program will continue to show the menu and execute the menu options until "Exit" is selected by entering the value 2 at the menu prompt. 1. Enter name 2. Exit When the user enters the value 1 at the menu prompt, your program will ask for a name. As an example, if the user enters the name Jane (as in the example input above), the program will output: Customer: Jane 30 cents Change: 20 cents: 1 10 cents: 1 Page 4 of 12 Change values of 0 are not shown for this screen output. If the user enters a name at menu option 1 (eg: Donald), which is non-existent in the file and therefore not in the array of records, your program will print: Name: Donald Not found After processing the output for menu option 1, the menu is re-displayed. If the user enters 2 to exit, your program will write the name, coin, and change data (in comma separated value – CSV – format) to a file called change.csv. After writing the data to the file your program will close the file and exit. Each data line in change.csv will be in the format: name of person,total coin value,number of 50 cent coins, number of 20 cent coins,number of 10 cent coins,number of 5 cent coins So for example, in change.csv, the data line for Jane will look like the following (each value separated by a comma and the line terminated by newline): Jane,30,0,1,1,0 So in the example output, Jane has 30 cents in one 20 cent coin and one 10 cent coin. Though there are no 50 or 5 cent coins, the value 0 must be included in correct position. As input of the same name indicates the same individual the output data file change.csv cannot have repeated names. Your solution  should be modular in design.
