Compile the program with debug flags and use gdb to debug the program. Set a

breakpoint somewhere before the line that computes the value of the input angle in

radians $($line $16).$ Run the program and step the code from the breakpoint until after the

value of the angle in radians has been computed. Use gdb$\text{'}$s print command to report

the value of the input angle in radians when an input angle of $20$ degrees, $1$ st index $=$

$1\mathrm{.}33,$ and $2$ nd index $=1\mathrm{.}0$ are specified.

Add the following comments to the very beginning of the file:

$//$ EE $1301$

$//$ HW $0$

$//$ Your name

$\frac{\frac{?}{?}}{?}$ Your x$.500$ ID

$//$ Angle value

Replace "Your name" and "Your $x\mathrm{.}500$ ID$"$ with your actual name and ID respectively.

Replace "Angle value" with the decimal value reported by gdb in part $2.$

When you are done, name the source code file username$\_$hw$0.$cpp$.$ Here, you replace

username with your $x\mathrm{.}500$ ID$.$ For example, if your university email address is

smithx$1234$@umn.edu, your file should be named smithx$1234\_$hw$0.$cpp$.$

Autograder:

$(4$ pts$)$ Functionality $-$ add $"$in degrees" in the cout statement$($s$).$

Manual Grading

$(3$ pts$)$ Debugger $-$ find the angle in radians, add it to the header comments

$(3$ pts$)$ Coding Style $-$ header and comments with your name, etc.
