Assignment operator:
- • The assignment operator “=” is used to assign a value.
- • The assignment statements are used to designate a value to a variable.
Augmented assignment operator:
The operators such as “+”, “-”, “/”, “*” and “%” are used combine with the assignment operators is called as augmented assignment operator.

7. Long-Distance CallsA long-distance provider charges the following rates for telephone calls:
Rate Category Rate per MinuteDaytime (6:00 a.m. through 5:59 p.m.) $0.07Evening (6:00 p.m. through 11:59 p.m.) $0.12Off-Peak (midnight through 5:59 a.m.) $0.05Write a GUI application that allows the user to select a rate category (from a set of radio buttons), and enter the number of minutes of the call into an Entry widget. An info dialog box should display the charge for the call.
Name and Address
The Name and Address Problem
Write a GUI program that displays your name and address when a button is clicked. The program’s window should appear as the sketch on the left side of Figure 13-61 when it runs. When the user clicks the Show Info button, the program should display your name and address, as shown in the sketch on the right of the figure.
Exercise 1 Function and Structure [30 pts]
Please debug the following program and answer the following questions. There is a cycle in a linked
list if some node in the list can be reached again by continuously following the next pointer.
#include
typedef struct node {
int value;
struct node *next;
} node;
int 11_has_cycle (node *first)
if (first
==
node *head =

NULL) return 0;
first;
while (head->next != NULL) {
}
if (head
first) {
return 1; }
head = head->next;
return 0;
void test ll_has_cycle () {
int i;
node nodes [6];
for (i = 0; i < 6; i++) {
