‘’fprintf‘’ cannot be used in a loop？

i just want to use 'fprintf' to print some calculating results,can't it be exculated in the loop?

codes are as this

syms a b c d
x=a+b;
y=c+d;



for i=0:4;
   
fprintf('equation%d=%d;',i,x^2+y^2)

end

results are as this

Error using fprintf. 
There is no function defined for the 'sym' input. 
Error get_the_equation_use_fprintf (line 25). 
Fprintf

 ('equation%d=%d;',i, x ^ 2 + y ^ 2)

thanks a lot!!!
