Question

Given a code segment

for(i=1; i<10; i++) 

cout<<i; 

1. Rewrite the code using do….while loop 

2. What will be the output when i = 0? 

Give reason.

Answer 1

1. i = 1; 

do{

cout<<i;i++;

}while(i<10);

2. When i = 0, it will execute one more time. ie. the for loop execute 9 times but here this loop executes 10 times.
