/* Code generated by RoboBlockly v2.0 */ /* Problem Statement: Add two numbers a + b on a number line. Move the robot tick mark along the number line, first to the red line, and then to the green line with the two preplaced driveDistance blocks. Refresh to try another problem.*/ #include <chplot.h> #include <linkbot.h> CPlot plot; CLinkbotI robot; double radius = 1.75; // Sample: Perform 3 + 4 plot.noStrokeColor(); plot.fillColor("#009900"); plot.rectangle(0, 32, 18, 6); plot.strokeWidth(3); plot.text("Perform 3 + 4", PLOT_TEXT_LEFT, 1, 33); robot.traceColor("red", 4); robot.driveDistance(3, radius); robot.traceColor("blue", 4); robot.driveDistance(4, radius); robot.delaySeconds(3); printf("3 + 4 = 7.

Problem Statement: Look on the grid, given a + b. Modify the first Drive-Forward block to move the robot forward by a units and then modify the second Drive-Forward block to move the robot by another b units. Finally, use the robot's final position to answer "What's a + b?" in the answer prompt. Refresh to try another problem. Look at Hint or Solution for example |
