Q3. Evaluate the output of the following: #include int main(){ int a=8; if(a) printf("Hello"); else printf("World"); }
The output will be 'Hello' as the condition 'if(a)' will evaluate to true since 'a' is not equal to 0.

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
