Q2. Reverse linked list.
Ans. 
Reverse a linked list by changing the direction of its pointers.
• Create a new pointer to keep track of the previous node.

Q1. Evaluate the output of the following: #include int main(){ int a=8; if(a) printf("Hello"); else printf("World"); }
Ans. 
The output will be 'Hello' as the condition 'if(a)' will evaluate to true since 'a' is not equal to 0.
• The condition 'if(a)' will evaluate to true if 'a' is not equal to 0.

• In this case, 'a' is equal to 8 which is not equal to 0, so 'Hello' will be printed.

Q2. Predict the output of the following: #include int main() { int i; for(i=1;i<=5;printf("%d",i)) { i++; } }
Ans. 
The program will print numbers from 1 to 5 continuously without spaces.
• The for loop increments i by 1 each iteration

• The printf statement prints the value of i without a newline character

• The loop continues until i is greater than 5
