• Logic: scanf jab %s format specifier use karta hai, toh woh input tab tak read karta hai jab tak use koi Whitespace (Space, Tab, ya Newline) nahi milta.

• Execution: Input hai "CS 2023".

  • scanf ne "CS" read kiya.

  • Jaise hi usne Space dekha, usne read karna band kar diya.

• Output: Isliye P ka output sirf CS hoga.

2. Code Q: gets ka behavior

gets(s);

• Logic: gets() function puri line read karta hai jab tak use Newline (Enter key) nahi milta. Yeh Spaces ko bhi input ka part maanta hai.

• Execution: Input hai "CS 2023".

  • gets ne pura text padha kyunki beech mein space allow hota hai.

• Output: Isliye Q ka output CS 2023 hoga.
