If and Else statement run on second iteration of while loop

This might help you The Scanner.nextDouble method does not consume the last newline character of your input, and thus that newline is consumed in the next call to Scanner.nextLine. You're basically suffering from the same issue as noted in this post
A simple work around would be to read the value as a String and parse it to double, so to replace
double amount = reader.nextDouble();
double amount = Double.parseDouble(reader.nextLine());

A different statement for each for-loop iteration


Tag : matlab , By : Jason Jennings

seems to work fine In a 1xn array, n alphabets will be stored. That is why you see first three letters getting printed (i=1:3). Assuming all the statements do not have the same length, you could save A,B,C in a cell array. Then access it as usual.
v={A;B;C};
for i = 1:size(v,1) %always try to use size(v,1) instead of hard-coding.
   fprintf('%s',v{i,1})
end
v=[A;B;C];
for i = 1:size(v,1) %always try to use size(v,1) instead of hard-coding.
   fprintf('%s',v(i,:))
end

Statement-terminator (;) operator after iteration statement: Ends the iteration statement itself, or an invisible empty

will be helpful for those in need From a grammar standpoint, it terminates the statement. That's a pretty odd way to think about it though. while loops must have a body, so if you just write
while(true)
while (true) i++;
while (true) ;

it statement inside loop iteration for each expect statement, mocha

it fixes the issue I have this array of objects. ,
You might want to use forEach instead of map.
const expect = require('chai').expect;

describe('links', function() {
  let links = [
    { 
     url: 'some url 1',
     status: 200 
    },
    {
     url: 'some url 2',
     status: 200 
    }
  ]

  links.forEach(function(property) {
    it('link array to contain url string', function() {
      expect(property).to.have.property('url').to.be.a('string');
    });
    it('link array to contain status number', function() {
      expect(property).to.have.property('status').to.be.a('number');
    });
  });
});
> mocha



  links
    √ link array to contain url string
    √ link array to contain status number
    √ link array to contain url string
    √ link array to contain status number


  4 passing (14ms)
before(function() {
  it('will NOT work here', function() { });
});

it('will work here', function() {
  it('will NOT work here', function() { });      
});
describe('links', function() {

  let links = [];

  before(function() {
    links = [
      { 
       url: 'some url 1',
       status: 200 
      },
      {
       url: 'some url 2',
       status: 200 
      }
    ];
  });

  // This won't work...
  links.forEach(function(property) {
    // .. since links is still an empty array when this runs
    it('should...', function() { /* ... */ });
  });

});

Using for loop iteration with If statement


Tag : python , By : Praetoriansentry

wish helps you It is printed multiple times, because there are multiple times where the current value does not match. A simple way to fix this is to use a flag, like so:
value_found = False 

for x in range(len(regs)):
    rex = regs[x]
    if re.match(rex,hostname):
        print (dev[x],'Regex matched')
        value_found = True
        break

if not value_found:
    print('wrong_format')

For loop statement not reading if statement to continue to next iteration

seems to work fine You seem to be comparing the value incorrectly. You are trying to compare a string "5" to an integer 5.
if item.data["position"] == '5':
print(1 == "1")
print(1 == 1)
