With +* the current line being that cout statement, Step Into again. +* 6) What happened? Where are we now? What is all of this nasty +* looking code? +* 7) Remember, stepping into a predefined routine takes you to the +* code for that routine. If the debugger can't find the code it +* will show the assembly code for that routine. +* 8) How do we get out of this mess? Use the "Step Out" tool. +* 9) In Visual Studio you will be taken back to the same cout +* statement. Use the Step Over tool to take you to the next +* line. +* 10) Step over the next cout statement. Now look at the console +* window. What was printed? +* Enter percent raise: +* 11) Select Stop Debugging either from the Debug menu or from your +* toolbar. +* +* Debugging Exercise 2 +* +* 1) With the program stopped, run to Breakpoint 1 by selecting +* the Start Debugging menu option, toolbar icon or press F5. +* 2) Step over the cout. +* 3) Step over the cin.

What is the value of money? +* 123.449997 +* 7) Hover your mouse pointer over raise. What is its value? +* .1 +* 8) Step over the calculation. Notice the watch on money is now +* red. This designates that the variable just changed its value. +* 9) What happened to our money? I thought a raise was supposed +* to increase our money? Stop debugging and fix the calculation. +* +* Debugging Exercise 3 +* +* 1) Choose Disable All Breakpoints from the Debug menu. +* 2) With the cursor on the calculation, Run to Cursor. Remember +* that the Run to Cursor tool can be accessed by right clicking +* in the code window and choosing the correct menu option. +* 3) Step over the calculation and verify that this time +* you end up with more money than before the raise. +* 4) Stop debugging. Now run the entire program by choosing the menu +* option Start Without Debugging. +* +********************************************************************/ + +#include <iostream> +#include <iomanip> +using std::cout; +using std::cin; +using std::endl; + +int main() +{ + float money = 123.45F; + float raise; + + cout << "You have $"; + cout << money << endl; + + // Breakpoint 1 + // Put a breakpoint on the following line + cout << "Enter percent raise: "; + cin >> raise; + + money = money + money * raise; + + cout << "After your raise you have $"; + cout << money << endl; + + return 0; +}
