For example, to get the factorial of n where n is in int. The result is the final value of fac.

long fac=1;
int i=1;
while ( i<=n ) { // the condition for execution of the loop
fac *= i; // the previous factorial (factorial of i-1)is multiplied by the current i
i++; // i has one increment
}

long fac=1;
int i=1;
do{
fac *= i; // the previous factorial (factorial of i-1)is multiplied by the current i
i++; // i has one increment
}while ( i<=n ) // the condition for execution of the loop

long fac=1;
for (int i=1; i<=n; i++) // the control variable i is initiated with 1
fac = fac*i; // the previous factorial (factorial of i-1)is multiplied by the current i
