for loop vs while loop
- by Atul
We can use for loop and while loop for same purpose.
in what means they effect our code if I use for instead of while? same question arises between if-else and switch-case? how to decide what to use?
for example which one you would prefer?
This code:
int main()
{
int n;
cin>>n;
for(int i=0;i<n;i++)
{
do_something();
}
return 0;
}
Or this code:
int main()
{
int n,i=0;
cin>>n;
while(i<n)
{
do_something();
i++;
}
return 0;
}
if using for or while loop does not effect the code by any means then may I know What was the need to make 2 solution for same problem?
