While loop

Program which writes freecprograms five(5) times.

#include<iostream.h>

int main()
{
int i=0;
while(i<5)
{
i++;
cout<<"freecprograms"<<endl;
}
}

Do While loop

It is very similar to the while loop shown above. The only difference being, in a 'while' loop, the condition is checked beforehand, but in a 'do while' loop, the condition is checked after one execution of the loop as we explained you in our C basic tutorial.

lets write the above program using do while loop.

#include <iostream.h>
int main()
{
int i=0;
do
{
i++;
cout<<"freecprograms"<<endl;
}

while(i<5);
}

For Loop

Lets print the numbers 1 to 5, using a for loop.

#include<iostream.h>

int main()

{

for(int k=1;k<=5;k++)

cout<<k<<endl;

}
