A little programming help...

I am not quite as adept in programming as in mathematics, so I was just wondering if any of you could possibly help me with writing a program, preferably in C++, that will solve the below equation for all values of x generated by an array of values for y, and then store the values of x obtained somewhere for use in a scatter-plot:

y=(pi)^x,

Any help would not only be a great assest for cutting down the time of the research I am working on, but would be greatly appreciated as well. Thank you in advance!

double y[100],x[100];
for (int i=0; i<100; ++i) {
y[i]=(double)4*i/100;
x[i]=log(y[i])/log(M_PI);
}
