FAQs on Lecture 22 Preprocessor Command #define #undef in C Language Hindi Video Lecture - C Programming for Beginners: From Zero to Hero (in Hindi) - Back-End Programming
| 1. #define प्रीप्रोसेसर कमांड क्या है? |  |
| 2. #undef प्रीप्रोसेसर कमांड क्या करता है? | |
उत्तर: #undef प्रीप्रोसेसर कमांड C भाषा में एक प्रीप्रोसेसर डिरेक्टिव है जो पहले से परिभाषित नाम को अवरोधित करती है। यह उपयोगकर्ता द्वारा परिभाषित नामों को रद्द करने की सुविधा प्रदान करता है जो बाद में प्रोग्राम के अन्य हिस्सों में इस्तेमाल नहीं किए जाएंगे।
| 3. #define और #undef का उपयोग किसलिए किया जाता है? | |
उत्तर: #define और #undef प्रीप्रोसेसर कमांड उपयोगकर्ता को नाम स्ट्रिंग के साथ एक मैक्रो परिभाषित करने की सुविधा प्रदान करते हैं। यह उपयोगकर्ता को प्रोग्राम के भौतिक और वैश्विक नामों को परिभाषित करने में मदद करता है जो बाद में प्रोग्राम के अन्य हिस्सों में इस्तेमाल किए जा सकते हैं।
| 4. #define कमांड के उदाहरण क्या हैं? | |
उत्तर: एक उदाहरण के रूप में, हम एक संक्षेप मैक्रो को परिभाषित कर सकते हैं:
#define PI 3.14
इसके बाद, हम इसे पूरे प्रोग्राम में उपयोग कर सकते हैं जैसे:
float area = PI * radius * radius;
| 5. #undef कमांड के उदाहरण क्या हैं? | |
उत्तर: एक उदाहरण के रूप में, हम एक पहले से परिभाषित मैक्रो को रद्द कर सकते हैं:
#undef PI
इसके बाद, हम इसे पूरे प्रोग्राम में उपयोग नहीं कर सकते हैं और कोई त्रुटि उत्पन्न हो सकती है।
