    Question about Eclipse Platform

    How exactly do I compile and run C++ code in eclipse as though it were in pico? I've wrote code that I know works, just a simple "Hello World" program, but I can't figure out how to make the one file program run!

    C/C++ C++ How do I call a specific line from an input file?

    just flip through the papers until I find what I want? Haha I don't know! Would I input everything, then use my if statements to find the line? Or just use the if statement from the get-go to find the line in the document, and only input that line into the rest of my code?

    C/C++ C++ How do I call a specific line from an input file?

    Alright, so my current class assignment is to create a program that will read several accounts, whether or not its a savings, the amount in the acocunt, then make calculations for interest and fines based on that info. The setup for the input file is like this: account checking/savings amount...

    Comp Sci Efficient C++ Data Read/Write Program for Employee Pay Increase Calculation

    Alright, so basicly I'm writing a program that will copy three people's first and last name, current pay, and pay increase %. Then, write it to a file that gives their name, and new pay after the increase has been applied to the current pay. When I launch the program, then open the output file...

    Converting to component form help.

    Let A = (4.6 m, 20^{}o south of east) How do I write this in compnent form? I know if it were (4.6m, North) is would simply be (0,4.6), but otherwise, how would I calculate this?

    Solving Particle Trajectory: Speed & Direction at t=4.5s

    Alright, so i don't know why I wasnt getting the right answer before(i was taking the derivatives), but I took the derivatives for x and y, then used the sqrt(x^2+y^2) to get part one. Then y=cos^-1(x/v) for part two.

    What Are the Solutions to bx^2 + cx + a = 0 for Any Constants a, b, and c?

    for part 'b', you would want to use the quadratic formula.

    Solving Particle Trajectory: Speed & Direction at t=4.5s

    A particle's trajectory is described by x=((1/2)t^3 - 2t^2) and y=((1/2)t^2-2t) , where t is in s. What is the particle's speed at t= 4.5 s? What is the particle's direction of motion, measured as an angle from the x-axis, at t=4.5 s? I keep geting the wrong answers >:0 , how do I go...
