I want to repeat my input command and the if-else statement. The input has to be positive and must include 0 and not include inf.

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;
else
    disp('Invalid Code');
end
    end
end

For some reason the code is not repeating.

Answer 1

[KALYAN ACHARJYA]

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;
