I get the following info from user
-Grid size
-Number of steps
-Percent chance of walking up, down, left and right (totally 100%)


Need some help setting this up,
So first get the info from them, then I would do a for loop for total number of steps they gave me, generate random up,down,left,right.

When they hit a boundary, the walking stops.
This is the code I was given. How do i find the random number with percentage changes they gave?

Believe I am suppose to set 3 boundary meeting functions


r = random();
if(r < Left) {
x = x-1;
} else if(r <Left+Right) {
x = x+1;
} else if(r<Left+Right+Up) {
y = y+1;
} else {
y = y-1;
}



e/ He says to have 3 random walking boundry functions (they give us up,left, right percentage values, we assume its down if its not one of the three)

I c, to get the random number just generate one between 1 and 100 then compare it to the up,down,left and right percentages.



still not sure where I incorporate these boundary checking functions in

if x > x_max...
if x < x_min....
etc

for(int i = 0 ; i < totalSteps; i++){

r = random();
if(r < Left) {
x = x-1;
} else if(r <Left+Right) {
x = x+1;
} else if(r<Left+Right+Up) {
y = y+1;
} else {
y = y-1;
}

if(x>=maxX || x<= minX || y>=maxY || y<=minY){
break;
}
}
