This lesson is called variables in envelopes.
इस पाठ का नाम है लिफाफे में वेरिएबल।
We're going to learn how we can build sentences when we're still missing pieces of information.
हम सीखेंगे कि पर्याप्त जानकारी ना होने पर भी हम कैसे वाक्यों का निर्माण कर सकते है।
Most of us are already familiar with the idea of filling in a blank.
हम में से अधिकांश पहले से ही एक 'रिक्त स्थान' को भरने के विचार से परिचित हैं।
We do it when we're putting our name on our homework.
हम ऐसा तब करते हैं जब हम अपना नाम अपने होमवर्क पर लिख रहे होते हैं।
Sometimes, there's more than one blank that needs to be filled out, and in that case,
कभी कभी एक से ज्यादा रिक्त स्थान होते हैं जिन्हें भरना होता है। इस मामले मे, हम रिक्त स्थान पर एक लेबेल लगाते है
we give the blank a label so that we know which piece of information goes where.
जिससे हमे पता चलता है की हर एक जानकारी कहां जा रही है।
Variables are placeholders for pieces of information that can change.
वेरिएबल जानकारी के टुकड़ों के लिए प्लेसहोल्डर हैं जो बदल सकते हैं।
By using a variable for the missing information, we can continue working on whatever we were doing,
उस गुम जानकारी के वेरिएबल को उपयोग करके, हम जो भी कर रहे थे उसको जारी रख सकते हैं
and let someone else fill in information later.
किसी और को बाद में उस गुम हुए जानकारी को भरने दीजिए।
In software, we use variables a lot.
सॉफ्टवेयर में हम वेरिएबल का उपयोग बहुत ज्यादा करते हैं।
We use variables as placeholders for name, email address, and even username.
हम नाम, ईमेल एड्रैस और यहां तक ​​कि यूसरनेम के लिए प्लेसहोल्डर के रूप में वेरिएबल का उपयोग करते हैं।
That way, we can let the program know where those details will appear
इस तरीके से हम प्रोग्राम को बताते हैं कि कहां वो विवरण मिलेंगे,
after the user fills them in.
उपयोगकर्ता द्वारा उन्हें भरने के बाद।
We use variables all the time in our work.
हम हर समय वेरिएबल का उपयोग करते हैं।
Any time you need to store a piece of information for later, we use a variable. Let's say we
किसी भी समय अगर आप बाद के लिए जानकारी को संग्रहित करना चाहते हैं, तो हम एक वेरिएबल का उपयोग करते हैं।
Let's say we need to count the number of times the user has tweeted. Every time that user tweets, we'll add one to that number.
जैसे, हम गिनना चाहते हैं कितनी बार एक उपयोगकर्ता ट्वीट करता है हर बार जब उपयोगकर्ता ट्विट करेगा, तो उसमें संख्या 1 जोड़ दी जाएगी
And every time the user deletes a tweet, we'll decrease that number by one.
और जब उपयोगकर्ता एक ट्वीट डिलीट कर देगा तो उस संख्या से 1 कम हो जाएगा।
Anytime we need to know how many times that user has tweeted,
किसी भी समय अगर हमको जानना है कि उपयोगकर्ता ने कितनी बार ट्वीट किया है
we'll just look at that variable.
हम बस उस वेरिएबल को देखेंगे। Subtitles by the Amara.org community
