clear;
clc;
A =input('Enter the Code: ');
if A>=0 && A~=inf
B = A;
else
disp('Invalid Code');
while A<0 && A==inf
A =input('Enter the Code: ');
if A>=0 && A~=inf
B = A;
break;

cond=1;
while cond==1
A=input('Enter the Code: ');
if A>=0 && A~=inf
B=A
cond=0;
else
disp('Invalid Code');
end
end
Or
A=input('Enter the Code: ');
while A<0 || A==inf
disp('Invalid Code');
A=input('Enter the Code: ');
end
B=A;
