Class Test 3. Question 1

Transcription

1 Class Test 3 Question 1 Create a windows forms application in CSEC that asks the user for his name and age that he/she will be this year. Calculate the year the user was born in and use a messagebox to greet the user and display the year he/she was born in. See figure 1 for example. Only the first label s position is hardcoded, positions of all the rest of the labels, textboxes and buttons should be relative to the first label. Meaning if I change the position of the first label, all the rest of the controls will alter their position to fit with the new position of the first label. See figure 2. Figure 1 Figure 2 Question 2 Create a windows forms application in CSEC that asks the user for the total amount of cents. Calculate the amount of R5, R2, R1, 50c, 20c, 10c, 5c and remaining 1c coins that will go into the total amount of cents inputted by the user. See Figure 3 as an example. Again only the first label s position is allowed to be hardcoded, the rest of the controls positions are linked to the first label or each other.
